Signal/Connection Descriptions Power POWER Table 1-2 Power Inputs Power Name VCCP Description PLL Power--VCCP provides isolated power for the Phase Lock Loop (PLL). The voltage should be well-regulated and the input should be provided with an extremely low impedance path to the VCC power rail. Quiet Power--VCCQ provides isolated power for the internal processing logic. This input must be tied externally to all other chip power inputs. The user must provide adequate external decoupling capacitors. Address Bus Power--VCCA provides isolated power for sections of the address bus I/O drivers. This input must be tied externally to all other chip power inputs. The user must provide adequate external decoupling capacitors.

VCCA VCCD VCCS GROUND Table 1-3 Grounds Ground Name GNDP Description PLL Ground--GNDP is ground dedicated for PLL use. The connection should be provided with an extremely low-impedance path to ground. VCCP should be bypassed to GNDP by a 0.47 F capacitor located as close as possible to the chip package. Quiet Ground--GNDQ provides isolated ground for the internal processing logic. This connection must be tied externally to all other chip ground connections.

Signal/Connection Descriptions Clock and PLL signals CLOCK AND PLL SIGNALS Note: While the PLL on this DSP is identical to the PLL described in the DSP56000 Family Manual, two of the signals have not been implemented externally. Specifically, there is no PLOCK signal or CKOUT signal available. Therefore, the internal clock is not directly accessible and there is no external indication that the PLL is locked. These signals were omitted to reduce the number of pins and allow this DSP to be put in a smaller, less expensive package. Table 1-4 Clock and PLL Signals Freescale Semiconductor, Inc... Signal Name EXTAL Signal Type Input State during Reset Input Signal Description External Clock/Crystal--This input should be connected to an external clock source. If the PLL is enabled, this signal is internally connected to the on-chip PLL. The PLL can multiply the frequency on the EXTAL pin to generate the internal DSP clock. The PLL output is divided by two to produce a four-phase instruction cycle clock, with the minimum instruction time being two PLL output clock periods. If the PLL is disabled, EXTAL is divided by two to produce the four-phase instruction cycle clock. PLL Filter Capacitor--This input is used to connect a highquality (high "Q" factor) external capacitor needed for the PLL filter. The capacitor should be as close as possible to the DSP with heavy, short traces connecting one terminal of the capacitor to PCAP and the other terminal to VCCP. The required capacitor value is specified in Table 2-6 on page 2-6. Note: When short lock time is critical, low dielectric absorption capacitors such as polystyrene, polypropylene, or teflon are recommended. PCAP Input Input If the PLL is not used (i.e., it remains disabled at all times), there is no need to connect a capacitor to the PCAP pin. It may remain unconnected, or be tied to either Vcc or GND. PINIT Input Input PLL Initialization (PINIT)--During the assertion of hardware reset, the value on the PINIT line is written into the PEN bit of the PCTL register. When set, the PEN bit enables the PLL by causing it to derive the internal clocks from the PLL voltage controlled oscillator output. When the bit is cleared, the PLL is disabled and the DSP's internal clocks are derived from the clock connected to the EXTAL signal. After hardware RESET is deasserted, the PINIT signal is ignored. 1-4 DSP56004/D, Rev. 3 For More Information On This Product, Go to: www.freescale.com MOTOROLA Freescale Semiconductor, Inc.

Signal/Connection Descriptions Interrupt and Mode Control INTERRUPT AND MODE CONTROL The interrupt and mode control signals select the DSP's operating mode as it comes out of hardware reset and receives interrupt requests from external sources after reset. Table 1-7 Interrupt and Mode Control Signals Signal Name Signal Type Input State during Reset Signal Description Freescale Semiconductor, Inc... MODA Input (MODA) Mode Select A--This input signal has three functions: * * * to work with the MODB and MODC signals to select the DSP's initial operating mode, to allow an external device to request a DSP interrupt after internal synchronization, and to turn on the internal clock generator when the DSP is in the Stop processing state, causing the DSP to resume processing. MODA is read and internally latched in the DSP when the processor exits the Reset state. The logic state present on the MODA, MODB, and MODC pins selects the initial DSP operating mode. Several clock cycles after leaving the Reset state, the MODA signal changes to the external interrupt request IRQA. The DSP operating mode can be changed by software after reset. IRQA External Interrupt Request A (IRQA)--The IRQA input is a synchronized external interrupt request. It may be programmed to be level-sensitive or negative-edgetriggered. When the signal is edge-triggered, triggering occurs at a voltage level and is not directly related to the fall time of the interrupt signal. However, as the fall time of the interrupt signal increases, the probability that noise on IRQA will generate multiple interrupts also increases. While the DSP is in the Stop mode, asserting IRQA gates on the oscillator and, after a clock stabilization delay, enables clocks to the processor and peripherals. Hardware reset causes this input to function as MODA. MOTOROLA DSP56004/D, Rev. 3 For More Information On This Product, Go to: www.freescale.com 1-7 Freescale Semiconductor, Inc. Signal/Connection Descriptions Interrupt and Mode Control Table 1-7 Interrupt and Mode Control Signals (Continued) Signal Name MODB Signal Type Input State during Reset Signal Description Input (MODB) Mode Select B--This input signal has two functions: * * to work with the MODA and MODC signals to select the DSP's initial operating mode, and to allow an external device to request a DSP interrupt after internal synchronization. Freescale Semiconductor, Inc... MODB is read and internally latched in the DSP when the processor exits the Reset state. The logic state present on the MODA, MODB, and MODC pins selects the initial DSP operating mode. Several clock cycles after leaving the Reset state, the MODB signal changes to the external interrupt request IRQB. The DSP operating mode can be changed by software after reset. IRQB External Interrupt Request B (IRQB)--The IRQB input is a synchronized external interrupt request. It may be programmed to be level-sensitive or negative-edgetriggered. When the signal is edge-triggered, triggering occurs at a voltage level and is not directly related to the fall time of the interrupt signal. However, as the fall time of the interrupt signal increases, the probability that noise on IRQB will generate multiple interrupts also increases. Hardware reset causes this input to function as MODB. 1-8 DSP56004/D, Rev. 3 For More Information On This Product, Go to: www.freescale.com MOTOROLA Freescale Semiconductor, Inc. Signal/Connection Descriptions Interrupt and Mode Control Table 1-7 Interrupt and Mode Control Signals (Continued) Signal Name MODC Signal Type Input, edgetriggered State during Reset Signal Description Input (MODC) Mode Select C--This input signal has two functions: * * to work with the MODA and MODB signals to select the DSP's initial operating mode, and to allow an external device to request a DSP interrupt after internal synchronization. Freescale Semiconductor, Inc... MODC is read and internally latched in the DSP when the processor exits the Reset state. The logic state present on the MODA, MODB, and MODC pins selects the initial DSP operating mode. Several clock cycles after leaving the Reset state, the MODC signal changes to the Non-Maskable Interrupt request, NMI. The DSP operating mode can be changed by software after reset. NMI Non-Maskable Interrupt Request--The NMI input is a negative-edge-triggered external interrupt request. This is a level 3 interrupt that can not be masked out. Triggering occurs at a voltage level and is not directly related to the fall time of the interrupt signal. However, as the fall time of the interrupt signal increases, the probability that noise on NMI will generate multiple interrupts also increases. Hardware reset causes this input to function as MODC. input active RESET--This input causes a direct hardware reset of the processor. When RESET is asserted, the DSP is initialized and placed in the Reset state. A Schmitt-trigger input is used for noise immunity. When the reset signal is deasserted, the initial DSP operating mode is latched from the MODA, MODB, and MODC signals. The DSP also samples the PINIT signal and writes its status into the PEN bit of the PLL Control Register. When the DSP comes out of the Reset state, deassertion occurs at a voltage level and is not directly related to the rise time of the RESET signal. However, the probability that noise on RESET will generate multiple resets increases with increasing rise time of the RESET signal. For proper hardware reset to occur, the clock must be active, since a number of clock ticks are required for proper propagation of the hardware Reset state.

Signal/Connection Descriptions Serial Host Interface (SHI) SERIAL HOST INTERFACE (SHI) The Serial Host Interface (SHI) has five I/O signals, which may be configured to operate in either SPI or I2C mode. Table 1-8 lists the SHI signals. Table 1-8 Serial Host Interface (SHI) signals Signal Name Signal Type Input or Output State during Reset Tri-stated Signal Description Freescale Semiconductor, Inc... SCK SPI Serial Clock (SCK)--The SCK signal is an output when the SPI is configured as a master, and a Schmitttrigger input when the SPI is configured as a slave. When the SPI is configured as a master, the SCK signal is derived from the internal SHI clock generator. When the SPI is configured as a slave, the SCK signal is an input, and the clock signal from the external master synchronizes the data transfer. The SCK signal is ignored by the SPI if it is defined as a slave and the Slave Select (SS) signal is not asserted. In both the master and slave SPI devices, data is shifted on one edge of the SCK signal and is sampled on the opposite edge where data is stable. Edge polarity is determined by the SPI transfer protocol. I2C Serial Clock (SCL)--SCL carries the clock for bus transactions in the I2C mode. SCL is a Schmitt-trigger input when configured as a slave, and an open-drain output when configured as a master. SCL should be connected to VCC through a pull-up resistor. The maximum allowed internally generated bit clock frequency is Fosc/4 for the SPI mode and Fosc/6 for the I2C mode where Fosc is the clock on EXTAL. The maximum allowed externally generated bit clock frequency is Fosc/3 for the SPI mode and Fosc/5 for the I2C mode. This signal is tri-stated during hardware reset, software reset, or individual reset (no need for external pull-up in this state).

Signal/Connection Descriptions Serial Host Interface (SHI) Table 1-8 Serial Host Interface (SHI) signals (Continued) Signal Name Signal Type Input or Output State during Reset Tri-stated Signal Description MISO Freescale Semiconductor, Inc... SPI Master-In-Slave-Out (MISO)--When the SPI is configured as a master, MISO is the master data input line. The MISO signal is used in conjunction with the MOSI signal for transmitting and receiving serial data. This signal is a Schmitt-trigger input when configured for the SPI Master mode, an output when configured for the SPI Slave mode, and tri-stated if configured for the SPI Slave mode when SS is deasserted. I2C Serial Data and Acknowledge (SDA)--In I2C mode, SDA is a Schmitt-trigger input when receiving and an open-drain output when transmitting. SDA should be connected to VCC through a pull-up resistor. SDA carries the data for I2C transactions. The data in SDA must be stable during the high period of SCL. The data in SDA is only allowed to change when SCL is low. When the bus is free, SDA is high. The SDA line is only allowed to change during the time SCL is high in the case of Start and Stop events. A high-to-low transition of the SDA line while SCL is high is an unique situation, and is defined as the Start event. A low-to-high transition of SDA while SCL is high is an unique situation, and is defined as the Stop event. Note: This line is tri-stated during hardware reset, software reset, or individual reset (no need for external pull-up in this state). SDA Input or Output MOSI Input or Output Tri-stated SPI Master-Out-Slave-In (MOSI)--When the SPI is configured as a master, MOSI is the master data output line. The MOSI signal is used in conjunction with the MISO signal for transmitting and receiving serial data. MOSI is the slave data input line when the SPI is configured as a slave. This signal is a Schmitt-trigger input when configured for the SPI Slave mode. I2C Slave Address 0 (HA0)--This signal uses a Schmitttrigger input when configured for the I2C mode. When configured for I2C Slave mode, the HA0 signal is used to form the slave device address. HA0 is ignored when the SHI is configured for the I2C Master mode. Note: This signal is tri-stated during hardware reset, software reset, or individual reset (no need for external pull-up in this state). HA0 Input MOTOROLA DSP56004/D, Rev. 3 For More Information On This Product, Go to: www.freescale.com 1-11 Freescale Semiconductor, Inc. Signal/Connection Descriptions Serial Host Interface (SHI) Table 1-8 Serial Host Interface (SHI) signals (Continued) Signal Name Signal Type Input State during Reset Tri-stated Signal Description SS Freescale Semiconductor, Inc... SPI Slave Select (SS)--This signal is an active low Schmitt-trigger input when configured for the SPI mode. When configured for the SPI Slave mode, this signal is used to enable the SPI slave for transfer. When configured for the SPI Master mode, this signal should be kept deasserted. If it is asserted while configured as SPI master, a bus error condition will be flagged. I2C Slave Address 2 (HA2)--This signal uses a Schmitt-trigger input when configured for the I2C mode. When configured for the I2C Slave mode, the HA2 signal is used to form the slave device address. HA2 is ignored in the I2C Master mode. If SS is deasserted, the SHI ignores SCK clocks and keeps the MISO output signal in the high-impedance state. Note: This signal is tri-stated during hardware reset, software reset, or individual reset (no need for external pull-up in this state). HA2 Input HREQ Input or Output Tri-stated Host Request--This signal is an active low Schmitttrigger input when configured for the Master mode, but an active low output when configured for the Slave mode. When configured for the Slave mode, HREQ is asserted to indicate that the SHI is ready for the next data word transfer and deasserted at the first clock pulse of the new data word transfer. When configured for the Master mode, HREQ is an input and when asserted by the external slave device, it will trigger the start of the data word transfer by the master. After finishing the data word transfer, the master will await the next assertion of HREQ to proceed to the next transfer. Note: This signal is tri-stated during hardware, software, individual reset, or when the HREQ[1:0] bits (in the HCSR) are cleared (no need for external pull-up in this state). 1-12 DSP56004/D, Rev. 3 For More Information On This Product, Go to: www.freescale.com MOTOROLA Freescale Semiconductor, Inc.

SAI Receiver Section Table 1-9 Serial Audio Interface (SAI) Receiver signals Freescale Semiconductor, Inc... Signal Name SDI0 Signal Type Input State during Reset Tri-stated Signal Description Serial Data Input 0--While in the high impedance state, the internal input buffer is disconnected from the pin and no external pull-up is necessary. SDI0 is the serial data input for receiver 0. Note: This signal is high impedance during hardware or software reset, while receiver 0 is disabled (R0EN = 0), or while the DSP is in the Stop state. SDI1 Input Tri-stated Serial Data Input 1--While in the high impedance state, the internal input buffer is disconnected from the pin and no external pull-up is necessary. SDI1 is the serial data input for receiver 1. Note: This signal is high impedance during hardware or software reset, while receiver 1 is disabled (R1EN = 0), or while the DSP is in the Stop state. SCKR Input or Output Tri-stated Receive Serial Clock--SCKR is an output if the receiver section is programmed as a master, and a Schmitt-trigger input if programmed as a slave. While in the high impedance state, the internal input buffer is disconnected from the pin and no external pull-up is necessary. Note: SCKR is high impedance if all receivers are disabled (individual reset) and during hardware or software reset, or while the DSP is in the Stop state.

Signal/Connection Descriptions Serial Audio Interface (SAI) SAI Transmitter Section Table 1-10 Serial Audio Interface (SAI) Transmitter signals Signal Name SDO0 Signal Type Output State during Reset Driven High Signal Description Serial Data Output 0 (SDO0)--SDO0 is the serial output for transmitter 0. SDO0 is driven high if transmitter 0 is disabled, during individual reset, hardware reset, and software reset, or when the DSP is in the Stop state. Serial Data Output 1 (SDO1)--SDO1 is the serial output for transmitter 1. SDO1 is driven high if transmitter 1 is disabled, during individual reset, hardware reset and software reset, or when the DSP is in the Stop state. Serial Data Output 2 (SDO2)--SDO2 is the serial output for transmitter 2. SDO2 is driven high if transmitter 2 is disabled, during individual reset, hardware reset and software reset, or when the DSP is in the Stop state. Serial Clock Transmit (SCKT)--This signal provides the clock for the SAI. SCKT can be an output if the transmit section is configured as a master, or a Schmitt-trigger input if the transmit section is configured as a slave. When the SCKT is an output, it provides an internally generated SAI transmit clock to external circuitry. When the SCKT is an input, it allows external circuitry to clock data out of the SAI. Note: SCKT is high impedance if all transmitters are disabled (individual reset), during hardware reset, software reset, or while the DSP is in the Stop state. While in the high impedance state, the internal input buffer is disconnected from the pin and no external pull-up is necessary. Freescale Semiconductor, Inc...

WST is used to synchronize the data word and select the left/right portion of the data sample. Note: WST is high impedance if all transmitters are disabled (individual reset), during hardware or software reset, or while the DSP is in the Stop state. While in the high impedance state, the internal input buffer is disconnected from the pin and no external pull-up is necessary.

Each GPIO line can be configured individually as disconnected, open-drain output, standard output, or an input. Note: Hardware reset or software reset configures all the GPIO lines as disconnected (external circuitry connected to these pins may need pullups until the pins are configured for operation). Freescale Semiconductor, Inc... ON-CHIP EMULATION (OnCETM) PORT There are four signals associated with the OnCE port controller and its serial interface. Table 1-12 On-Chip Emulation Port Signals Signal Name DSI Signal Type Input State during Reset Output, Driven Low Signal Description Debug Serial Input (DSI)--The DSI signal is the signal through which serial data or commands are provided to the OnCE port controller. The data received on the DSI signal will be recognized only when the DSP has entered the Debug mode of operation. Data must have valid TTL logic levels before the serial clock falling edge. Data is always shifted into the OnCE port Most Significant Bit (MSB) first. Operating Status 0 (OS0)--When the DSP is not in the Debug mode, the OS0 signal provides information about the DSP status if it is an output and used in conjunction with the OS1 signal. When switching from output to input, the signal is tri-stated. Note: If the OnCE port is in use, an external pull-down resistor should be attached to the DSI/OS0 signal. If the OnCE port is not in use, the resistor is not required. OS0 Output 1-16 DSP56004/D, Rev. 3 For More Information On This Product, Go to: www.freescale.com MOTOROLA Freescale Semiconductor, Inc. Signal/Connection Descriptions On-Chip Emulation (OnCETM) Port Table 1-12 On-Chip Emulation Port Signals (Continued) Signal Name DSCK Signal Type Input State during Reset Output, Driven Low Signal Description Debug Serial Clock (DSCK)--The DSCK/OS1 signal, when an input, is the signal through which the serial clock is supplied to the OnCE port. The serial clock provides pulses required to shift data into and out of the OnCE port. Data is clocked into the OnCE port on the falling edge and is clocked out of the OnCE port on the rising edge. Operating Status 1 (OS1)--If the OS1 signal is an output and used in conjunction with the OS0 signal, it provides information about the DSP status when the DSP is not in the Debug mode. The debug serial clock frequency must be no greater than 1/8 of the processor clock frequency. The signal is tri-stated when it is changing from input to output. Note: If the OnCE port is in use, an external pull-down resistor should be attached to the DSCK/OS1 pin. If the OnCE port is not in use, the resistor is not required. Freescale Semiconductor, Inc... OS1 Output DSO Output Driven High Debug Serial Output (DSO)--The DSO line provides the data contained in one of the OnCE port controller registers as specified by the last command received from the command controller. The Most Significant Bit (MSB) of the data word is always shifted out of the OnCE port first. Data is clocked out of the OnCE port on the rising edge of DSCK. The DSO line also provides acknowledge pulses to the external command controller. When the DSP enters the Debug mode, the DSO line will be pulsed low to indicate that the OnCE port is waiting for commands. After receiving a read command, the DSO line will be pulsed low to indicate that the requested data is available and the OnCE port is ready to receive clock pulses in order to deliver the data. After receiving a write command, the DSO line will be pulsed low to indicate that the OnCE port is ready to receive the data to be written; after the data is written, another acknowledge pulse will be provided. Note: During hardware reset and when idle, the DSO line is held high. MOTOROLA DSP56004/D, Rev. 3 For More Information On This Product, Go to: www.freescale.com 1-17 Freescale Semiconductor, Inc. Signal/Connection Descriptions On-Chip Emulation (OnCETM) Port Table 1-12 On-Chip Emulation Port Signals (Continued) Signal Name DR Signal Type Input State during Reset Input Signal Description Debug Request (DR)--The debug request input provides a means of entering the Debug mode of operation. This signal, when asserted (pulled low), will cause the DSP to finish the current instruction being executed, to save the instruction pipeline information, to enter the Debug mode, and to wait for commands to be entered from the debug serial input line. While the DSP is in the Debug mode, the user can reset the OnCE port controller by asserting DR, waiting for an acknowledge pulse on DSO, and then deasserting DR. It may be necessary to reset the OnCE port controller in cases where synchronization between the OnCE port controller and external circuitry is lost. Asserting DR when the DSP is in the Wait or the Stop mode, and keeping it asserted until an acknowledge pulse in the DSP is produced, puts the DSP into the Debug mode. After receiving the acknowledge pulse, DR must be deasserted before sending the first OnCE port command. For more information, see Methods Of Entering The Debug Mode in the DSP56000 Family Freescale Semiconductor, Inc... Manual. Note: If the OnCE port is not in use, an external pull-up resistor should be attached to the DR line. 1-18 DSP56004/D, Rev. 3 For More Information On This Product, Go to: www.freescale.com MOTOROLA Freescale Semiconductor, Inc. SECTION 2 SPECIFICATIONS INTRODUCTION Freescale Semiconductor, Inc... The DSP56004 is fabricated in high density CMOS with Transistor-Transistor Logic (TTL) compatible inputs and outputs. MAXIMUM RATINGS CAUTION This device contains circuitry protecting against damage due to high static voltage or electrical fields; however, normal precautions should be taken to avoid exceeding maximum voltage ratings. Reliability is enhanced if unused inputs are tied to an appropriate logic voltage level (e.g., either GND or VCC). Note: In the calculation of timing requirements, adding a maximum value of one specification to a minimum value of another specification does not yield a reasonable sum. A maximum specification is calculated using a worst case variation of process parameter values in one direction. The minimum specification is calculated using the worst case for the same parameters in the opposite direction. Therefore, a "maximum" value for a specification will never occur in the same device that has a "minimum" value for another specification; adding a maximum to a minimum represents a condition that can never exist.

The SHI inputs are: MOSI/HA0, SS/HA2, MISO/SDA, SCK/SCL, and HREQ. In order to obtain these results, all inputs must be terminated (i.e., not allowed to float). PLL signals are disabled during Stop state. Periodically sampled and not 100% tested Maximum values are derived using the methodology described in Section 4. Actual maximums are application dependent and may vary widely from these numbers. AC ELECTRICAL CHARACTERISTICS The timing waveforms in the AC Electrical Characteristics are tested with a VIL maximum of 0.5 V and a VIH minimum of 2.4 V for all pins, except EXTAL, RESET, MODA, MODB, MODC, and SHI pins (MOSI/HA0, SS/HA2, MISO/SDA, SCK/ SCL, HREQ). These pins are tested using the input levels set forth in the DC Electrical Characteristics. AC timing specifications that are referenced to a device input signal are measured in production with respect to the 50% point of the respective input signal's transition. DSP56004 output levels are measured with the production test machine VOL and VOH reference levels set at 0.8 V and 2.0 V, respectively. All output delays are given for a 50 pF load unless otherwise specified. For load capacitance greater than 50 pF, the drive capability of the output pins typically decreases linearly: 1. At 1.5 ns per 10 pF of additional capacitance at all output pins except MOSI/ HA0, MISO/SDA, SCK/SCL, HREQ 2.

For capacitor values 2 nF, asserting RESET according to this timing requirement will ensure proper processor initialization for capacitors with a C/C < 0.5%. (This is typical for ceramic capacitors.) For capacitor values > 2 nF, asserting RESET according to this timing requirement will ensure proper processor initialization for capacitors with a C/C < 0.01%. (This is typical for Teflon, polystyrene, and polypropylene capacitors.) However, capacitors with values > 2 nF with a C/C > 0.01% may require longer RESET assertion to ensure proper initialization. When using fast interrupts and IRQA and IRQB are defined as level-sensitive, then timing 22 applies to prevent multiple interrupt service. To avoid these timing restrictions, the Negative Edge-triggered mode is recommended when using fast interrupts. Long interrupts are recommended when using Level-sensitive mode.

Specifications Serial Host Interface (SHI) I2C Protocol Timing The Programmed Serial Clock Cycle, t I2CCP , is specified by the value of the HDM5- HDM0 and HRS bits of the HCKR (SHI Clock control Register). The expression for t I2CCP is: t I CCP 2 = [ Tc x 2 x ( HDM[5:0] + 1 ) x ( 7 x ( 1 - HRS ) + 1 ) ] where * HRS is the Prescaler Rate Select bit. When HRS is cleared, the fixed divide-byeight prescaler is operational. When HRS is set, the prescaler is bypassed. HDM5-HDM0 are the Divider Modulus Select bits. A divide ratio from 1 to 64 (HDM5-HDM0 = 0 to $3F) may be selected. Freescale Semiconductor, Inc... * * In I2C mode, you may select a value for the Programmed Serial Clock Cycle from (HDM5-HDM0 = 2, HRS = 1) to 6 x TC (HDM5-HDM0 = $3F, HRS = 0). 1024 x TC The DSP56004 provides an improved I2C bus protocol. In addition to supporting the 100 kHz I2C bus protocol, the SHI in I2C mode supports data transfers at up to 1000 kHz. The actual maximum frequency is limited by the bus capacitances (CL),the pullup resistors (RP), (which affect the rise and fall time of SDA and SCL, (see table below)), and by the input filters. Consideration for programming the SHI Clock Control Register (HCKR) - Clock Divide Ratio: the master must generate a bus free time greater than T172 slave when operating with a DSP56004 SHI I2C slave. The table below describes a few examples: Table 2-14 Considerations for Programming the SHI Clock control Register (HCKR) Conditions to be Considered Resulting Limitations Bus Load Master Operating Freq.

Specifications Serial Host Interface (SHI) I2C Protocol Timing Example: for CL = 50 pF, RP = 2 k, f = 88 MHz, Bypassed Filter mode: The master, when operating with a DSP56004 SHI I2C slave with an 88 MHz operating frequency, must generate a bus free time greater than 36 ns (T172 slave). Thus, the minimum permissible tI2CCP is 56 x TC which gives a bus free time of at least 41 ns (T172 master). This implies a maximum I2C serial frequency of 1010 kHz. In general, bus performance may be calculated from the CL and RP of the bus, the Input Filter modes and operating frequencies of the master and the slave. Table 2-15 contains the expressions required to calculate all relevant performance timing for a given CL and RP. Table 2-15 SHI Improved I2C Protocol Timing Freescale Semiconductor, Inc...

SECTION 4 DESIGN CONSIDERATIONS THERMAL DESIGN CONSIDERATIONS Freescale Semiconductor, Inc... An estimation of the chip junction temperature, TJ, in C can be obtained from the equation: Equation 1: T J = T A + ( P D x R JA ) Where: TA = ambient temperature C RJA = package junction-to-ambient thermal resistance C/W PD = power dissipation in package Historically, thermal resistance has been expressed as the sum of a junction-to-case thermal resistance and a case-to-ambient thermal resistance: Equation 2: R JA = R JC + R CA Where: RJA = package junction-to-ambient thermal resistance C/W RJC = package junction-to-case thermal resistance C/W RCA = package case-to-ambient thermal resistance C/W RJC is device-related and cannot be influenced by the user. The user controls the thermal environment to change the case-to-ambient thermal resistance, RCA. For example, the user can change the air flow around the device, add a heat sink, change the mounting arrangement on the Printed Circuit Board, or otherwise change the thermal dissipation capability of the area surrounding the device on a Printed Circuit Board. This model is most useful for ceramic packages with heat sinks; some 90% of the heat flow is dissipated through the case to the heat sink and out to the ambient environment. For ceramic packages, in situations where the heat flow is split between a path to the case and an alternate path through the Printed Circuit Board, analysis of the device thermal performance may need the additional modeling capability of a system level thermal simulation tool. MOTOROLA DSP56004/D, Rev. 3 For More Information On This Product, Go to: www.freescale.com 4-1 Freescale Semiconductor, Inc. Design Considerations Thermal Design Considerations The thermal performance of plastic packages is more dependent on the temperature of the Printed Circuit Board to which the package is mounted. Again, if the estimations obtained from RJA do not satisfactorily answer whether the thermal performance is adequate, a system level model may be appropriate. A complicating factor is the existence of three common ways for determining the junction-to-case thermal resistance in plastic packages: * To minimize temperature variation across the surface, the thermal resistance is measured from the junction to the outside surface of the package (case) closest to the chip mounting area when that surface has a proper heat sink. To define a value approximately equal to a junction-to-board thermal resistance, the thermal resistance is measured from the junction to where the leads are attached to the case. If the temperature of the package case (TT) is determined by a thermocouple, the thermal resistance is computed using the value obtained by the equation (TJ - TT)/PD. Freescale Semiconductor, Inc... * * As noted above, the junction-to-case thermal resistances quoted in this data sheet are determined using the first definition. From a practical standpoint, that value is also suitable for determining the junction temperature from a case thermocouple reading in forced convection environments. In natural convection, using the junction-to-case thermal resistance to estimate junction temperature from a thermocouple reading on the case of the package will estimate a junction temperature slightly hotter than actual temperature. Hence, the new thermal metric, Thermal Characterization Parameter or JT, has been defined to be (TJ - TT)/PD. This value gives a better estimate of the junction temperature in natural convection when using the surface temperature of the package. Remember that surface temperature readings of packages are subject to significant errors caused by inadequate attachment of the sensor to the surface and to errors caused by heat loss to the sensor. The recommended technique is to attach a 40-gauge thermocouple wire and bead to the top center of the package with thermally conductive epoxy. 4-2 DSP56004/D, Rev. 3 For More Information On This Product, Go to: www.freescale.com MOTOROLA Freescale Semiconductor, Inc. Design Considerations Electrical Design Considerations ELECTRICAL DESIGN CONSIDERATIONS CAUTION This device contains protective circuitry to guard against damage due to high static voltage or electrical fields. However, normal precautions are advised to avoid application of any voltages higher than maximum rated voltages to this high-impedance circuit. Reliability of operation is enhanced if unused inputs are tied to an appropriate logic voltage level (e.g., either GND or VCC). Freescale Semiconductor, Inc... Use the following list of recommendations to assure correct DSP operation: * * Provide a low-impedance path from the board power supply to each VCC pin on the DSP, and from the board ground to each GND pin. Use at least four 0.01-0.1 F bypass capacitors positioned as close as possible to the four sides of the package to connect the VCC power source to GND. Ensure that capacitor leads and associated printed circuit traces that connect to the chip VCC and GND pins are less than 0.5 in per capacitor lead. Use at least a four-layer Printed Circuit Board (PCB) with two inner layers for VCC and GND. Because the DSP output signals have fast rise and fall times, PCB trace lengths should be minimal. This recommendation particularly applies to the address and data buses as well as the IRQA, IRQB, and NMI pins. Maximum Printed Circuit Board (PCB) trace lengths on the order of 6 inches are recommended. Consider all device loads as well as parasitic capacitance due to PCB traces when calculating capacitance. This is especially critical in systems with higher capacitive loads that could create higher transient currents in the VCC and GND circuits. All inputs must be terminated (i.e., not allowed to float) using CMOS levels, except as noted in Section 1. Take special care to minimize noise levels on the VCCP and GNDP pins. If multiple DSP56004 devices are on the same board, check for cross-talk or excessive spikes on the supplies due to synchronous operation of the devices. * * * * * * * MOTOROLA DSP56004/D, Rev. 3 For More Information On This Product, Go to: www.freescale.com 4-3 Freescale Semiconductor, Inc. Design Considerations Power Consumption Considerations POWER CONSUMPTION CONSIDERATIONS Power dissipation is a key issue in portable DSP applications. Some of the factors which affect current consumption are described in this section. Most of the current consumed by CMOS devices is Alternating Current (AC), which is charging and discharging the capacitances of the pins and internal nodes. Current consumption is described by the formula: Equation 3: I = C x V x f Freescale Semiconductor, Inc... where: C = node/pin capacitance V = voltage swing f = frequency of node/pin toggle Example 4-1 Current Consumption For an I/O pin loaded with 50 pF capacitance, operating at 5.5 V, and with a 81 MHz clock, toggling at its maximum possible rate (20 MHz), the current consumption is: Equation 4: I = 50 x 10 - 12 x 5.5 x 20 x 10 = 5.5mA 6 The Maximum Internal Current (ICCImax) value reflects the typical possible switching of the internal buses on best-case operation conditions, which is not necessarily a real application case. The Typical Internal Current (ICCItyp) value reflects the average switching of the internal buses on typical operating conditions. For applications that require very low current consumption: * * * * * Minimize the number of pins that are switching. Minimize the capacitive load on the pins. Connect the unused inputs to pull-up or pull-down resistors. Disable unused peripherals. Disable unused pin activity. 4-4 DSP56004/D, Rev. 3 For More Information On This Product, Go to: www.freescale.com MOTOROLA Freescale Semiconductor, Inc.

Design Considerations Power-Up Considerations POWER-UP CONSIDERATIONS To power-up the device properly, ensure that the following conditions are met: * * * * Stable power is applied to the device according to the specifications in Table 2-3 (DC Electrical Characteristics). The external clock oscillator is active and stable. RESET is asserted according to the specifications in Table 2-7 (Reset, Stop, Mode Select, and Interrupt Timing). The following input pins are driven to valid voltage levels: DR, PINIT, MODA, MODB, and MODC. Freescale Semiconductor, Inc... Care should be taken to ensure that the maximum ratings for all input voltages obey the restrictions on Table 2-1 (Maximum Ratings), at all phases of the power-up procedure. This may be achieved by powering the external clock, hardware reset, and mode selection circuits from the same power supply that is connected to the power supply pins of the chip. At the beginning of the hardware reset procedure, the device might consume significantly more current than the specified typical supply current. This is because of contentions among the internal nodes being affected by the hardware reset signal until they reach their final hardware reset state. 4-6 DSP56004/D, Rev. 3 For More Information On This Product, Go to: www.freescale.com MOTOROLA Freescale Semiconductor, Inc.
