2.0 Functional Description
4.2 8051 Microprocessor
EZ-USB FX1 (CY7C64713/4) is a full-speed highly integrated, USB microcontroller. By integrating the USB transceiver, serial interface engine (SIE), enhanced 8051 microcontroller, and a programmable peripheral interface in a single chip, Cypress has created a very cost-effective solution that provides superior time-to-market advantages. Because it incorporates the USB transceiver, the EZ-USB FX1 is more economical, providing a smaller footprint solution than USB SIE or external transceiver implementations. With EZ-USB FX1, the Cypress Smart SIE handles most of the USB protocol in hardware, freeing the embedded microcontroller for application-specific functions and decreasing development time to ensure USB compatibility. The General Programmable Interface (GPIF) and Master/ Slave Endpoint FIFO (8- or 16-bit data bus) provides an easy and glueless interface to popular interfaces such as ATA, UTOPIA, EPP, PCMCIA, and most DSP/processors. Three lead-free packages are defined for the family: 56 QFN, 100 TQFP, and 128 TQFP.
The 8051 microprocessor embedded in the FX1 family has 256 bytes of register RAM, an expanded interrupt system, three timer/counters, and two USARTs. 4.2.1 8051 Clock Frequency
FX1 has an on-chip oscillator circuit that uses an external 24MHz (100 ppm) crystal with the following characteristics: * Parallel resonant * Fundamental mode * 500-W drive level * 12-pF (5% tolerance) load capacitors. An on-chip PLL multiplies the 24-MHz oscillator up to 480 MHz, as required by the transceiver/PHY, and internal counters divide it down for use as the 8051 clock. The default 8051 clock frequency is 12 MHz. The clock frequency of the 8051 can be changed by the 8051 through the CPUCS register, dynamically. The CLKOUT pin, which can be three-stated and inverted using internal control bits, outputs the 50% duty cycle 8051 clock, at the selected 8051 clock frequency--48, 24, or 12 MHz. 4.2.2 USARTS

Applications
* DSL modems * ATA interface * Memory card readers * Legacy conversion devices * Home PNA * Wireless LAN * MP3 players * Networking The "Reference Designs" section of the cypress website provides additional tools for typical USB applications. Each reference design comes complete with firmware source and object code, schematics, and documentation. Please visit http://www.cypress.com for more information.
FX1 contains two standard 8051 USARTs, addressed via Special Function Register (SFR) bits. The USART interface pins are available on separate I/O pins, and are not multiplexed with port pins. UART0 and UART1 can operate using an internal clock at 230 KBaud with no more than 1% baud rate error. 230-KBaud operation is achieved by an internally derived clock source that generates overflow pulses at the appropriate time. The internal clock adjusts for the 8051 clock rate (48, 24, 12 MHz) such that it always presents the correct frequency for 230KBaud operation.[1] 4.2.3 Special Function Registers
Certain 8051 SFR addresses are populated to provide fast access to critical FX1 functions. These SFR additions are shown in Table 4-1. Bold type indicates non-standard, 4.1 USB Signaling Speed enhanced 8051 registers. The two SFR rows that end with "0" and "8" contain bit-addressable registers. The four I/O ports FX1 operates at one of the three rates defined in the USB A-D use the SFR addresses used in the standard 8051 for Specification Revision 2.0, dated April 27, 2000: ports 0-3, which are not implemented in FX1. Because of the * Full speed, with a signaling bit rate of 12 Mbps. faster and more efficient SFR addressing, the FX1 I/O ports are not addressable in external RAM space (using the MOVX FX1 does not support the low-speed signaling mode of 1.5 instruction).

4.3 I2C Bus 4.4 Buses
FX1 supports the I2C bus as a master only at 100/400 KHz. SCL and SDA pins have open-drain outputs and hysteresis inputs. These signals must be pulled up to 3.3V, even if no I2C device is connected.

This patented two-step process, called ReNumeration, happens instantly when the device is plugged in, with no hint that the initial download step has occurred. Two control bits in the USBCS (USB Control and Status) register control the ReNumeration process: DISCON and RENUM. To simulate a USB disconnect, the firmware sets DISCON to 1. To reconnect, the firmware clears DISCON to 0. Before reconnecting, the firmware sets or clears the RENUM bit to indicate whether the firmware or the Default USB Device will handle device requests over endpoint zero: if RENUM = 0, the Default USB Device will handle device requests; if RENUM = 1, the firmware will.

USB Boot Methods
I2C
During the power-up sequence, internal logic checks the port for the connection of an EEPROM whose first byte is either 0xC0 or 0xC2. If found, it uses the VID/PID/DID values in the EEPROM in place of the internally stored values (0xC0), or it boot-loads the EEPROM contents into internal RAM (0xC2). If no EEPROM is detected, FX1 enumerates using internally stored descriptors. The default ID values for FX1 are VID/PID/DID (0x04B4, 0x6473, 0xAxxx where xxx=Chip revision).[2] Table 4-2.

Interrupt System
INT2 Interrupt Request and Enable Registers
Because the FX1's configuration is soft, one chip can take on the identities of multiple distinct USB devices. When first plugged into USB, the FX1 enumerates automatically and downloads firmware and USB descriptor tables over the USB cable. Next, the FX1 enumerates again, this time as
Note: 2.
FX1 implements an autovector feature for INT2 and INT4. There are 27 INT2 (USB) vectors, and 14 INT4 (FIFO/GPIF) vectors. See EZ-USB Technical Reference Manual (TRM) for more details.
The I2C bus SCL and SDA pins must be pulled up, even if an EEPROM is not connected. Otherwise this detection method does not work properly.

4.8.2 USB-Interrupt Autovectors The main USB interrupt is shared by 27 interrupt sources. To save the code and processing time that normally would be required to identify the individual USB interrupt source, the FX1 provides a second level of interrupt vectoring, called Autovectoring. When a USB interrupt is asserted, the FX1 pushes the program counter onto its stack then jumps to address 0x0043, where it expects to find a "jump" instruction to the USB Interrupt service routine. The FX1 jump instruction is encoded as shown in Table 4-3. If Autovectoring is enabled (AV2EN = 1 in the INTSETUP register), the FX1 substitutes its INT2VEC byte. Therefore, if Table 4-3.

Just as the USB Interrupt is shared among 27 individual USBinterrupt sources, the FIFO/GPIF interrupt is shared among 14 individual FIFO/GPIF sources. The FIFO/GPIF Interrupt, like the USB Interrupt, can employ autovectoring. Table 4-4 shows the priority and INT4VEC values for the 14 FIFO/GPIF interrupt sources.

If Autovectoring is enabled (AV4EN = 1 in the INTSETUP register), the FX1 substitutes its INT4VEC byte. Therefore, if the high byte ("page") of a jump-table address is preloaded at location 0x0054, the automatically-inserted INT4VEC byte at 0x0055 will direct the jump to the correct address out of the 14 addresses within the page. When the ISR occurs, the FX1 pushes the program counter onto its stack then jumps to address 0x0053, where it expects to find a "jump" instruction to the ISR Interrupt service routine.

4.9.1
Reset and Wakeup
Reset Pin
The input pin, RESET#, will reset the FX1 when asserted. This pin has hysteresis and is active LOW. When a crystal is used with the CY7C64713/4 the reset period must allow for the stabilization of the crystal and the PLL. This reset period should be approximately 5 ms after VCC has reached 3.0 Volts. If the crystal input pin is driven by a clock signal the internal PLL stabilizes in 200 s after VCC has reached 3.0V[3]. Figure 4-2 shows a power on reset condition and a reset applied during operation. A power on reset is defined as the time reset is asserted while power is being applied to the circuit. A powered reset is defined to be when the FX1 has previously been powered on and operating and the RESET# pin is asserted. Cypress provides an application note which describes and recommends power on reset implementation and can be found on the Cypress web site. While the application note discusses the FX2, the information provided applies also to the FX1. For more information on reset implementation for the FX2 family of products visit the http://www.cypress.com.
Note: 3. If the external clock is powered at the same time as the CY7C64713/4 and has a stabilization wait period, it must be added to the 200 s.

The 8051 puts itself and the rest of the chip into a power-down mode by setting PCON.0 = 1. This stops the oscillator and PLL. When WAKEUP is asserted by external logic, the oscillator restarts, after the PLL stabilizes, and then the 8051 receives a wakeup interrupt. This applies whether or not FX1 is connected to the USB. The FX1 exits the power-down (USB suspend) state using one of the following methods: * USB bus activity (if D+/D- lines are left floating, noise on these lines may indicate activity to the FX1 and initiate a wakeup). * External logic asserts the WAKEUP pin * External logic asserts the PA3/WU2 pin. The second wakeup pin, WU2, can also be configured as a general purpose I/O pin. This allows a simple external R-C network to be used as a periodic wakeup source. Note that WAKEUP is by default active low.
This mode implements the internal 16-KByte block of RAM (starting at 0) as combined code and data memory. When external RAM or ROM is added, the external read and write strobes are suppressed for memory spaces that exist inside the chip. This allows the user to connect a 64-KByte memory without requiring address decodes to keep clear of internal memory spaces. Only the internal 16 KBytes and scratch pad 0.5 KBytes RAM spaces have the following access: * USB download * USB upload * Setup data pointer * I2C interface boot load. 4.10.3 External Code Memory, EA = 1
The bottom 16 KBytes of program memory is external, and therefore the bottom 16 KBytes of internal RAM is accessible only as data memory.

Figure 4-5. Endpoint Configuration Endpoints 0 and 1 are the same for every configuration. Endpoint 0 is the only CONTROL endpoint, and endpoint 1 can be either BULK or INTERRUPT. The endpoint buffers can be configured in any 1 of the 12 configurations shown in the vertical columns. In full-speed, BULK mode uses only the first 64 bytes of each buffer, even though memory exists for the allocation of the isochronous transfers in BULK mode the unused endpoint buffer space is not available for other operations. An example endpoint configuration would be: EP2--1023 double buffered; EP6--64 quad buffered (column 8). 4.12.5 Default Alternate Settings are controlled by FIFO control signals (such as IFCLK, SLCS#, SLRD, SLWR, SLOE, PKTEND, and flags). The usable size of these buffers depend on the USB transfer mode as described in Section 4.12.2. In operation, some of the eight RAM blocks fill or empty from the SIE, while the others are connected to the I/O transfer logic. The transfer logic takes two forms, the GPIF for internally generated control signals, or the slave FIFO interface for externally controlled transfers. 4.13.2 Master/Slave Control Signals

The FX1 endpoint FIFOS are implemented as eight physically distinct 256x16 RAM blocks. The 8051/SIE can switch any of the RAM blocks between two domains, the USB (SIE) domain and the 8051-I/O Unit domain. This switching is done virtually instantaneously, giving essentially zero transfer time between "USB FIFOS" and "Slave FIFOS." Since they are physically the same memory, no bytes are actually transferred between buffers.

At any given time, some RAM blocks are filling/emptying with USB data under SIE control, while other RAM blocks are available to the 8051 and/or the I/O control unit. The RAM blocks operate as single-port in the USB domain, and dualport in the 8051-I/O domain. The blocks can be configured as single, double, triple, or quad buffered as previously shown. The I/O control unit implements either an internal-master (M for master) or external-master (S for Slave) interface. In Master (M) mode, the GPIF internally controls FIFOADR[1..0] to select a FIFO. The RDY pins (two in the 56pin package, six in the 100-pin and 128-pin packages) can be used as flag inputs from an external FIFO or other logic if desired. The GPIF can be run from either an internally derived clock or externally supplied clock (IFCLK), at a rate that transfers data up to 96 Megabytes/s (48-MHz IFCLK with 16bit interface). In Slave (S) mode, the FX1 accepts either an internally derived clock or externally supplied clock (IFCLK, max. frequency 48 MHz) and SLCS#, SLRD, SLWR, SLOE, PKTEND signals from external logic. When using an external IFCLK, the external clock must be present before switching to the external clock with the IFCLKSRC bit. Each endpoint can individually be selected for byte or word operation by an internal configuration bit, and a Slave FIFO Output Enable signal SLOE enables data of the selected width. External logic must insure that the output enable signal is inactive when writing data to a slave FIFO. The slave interface can also operate asynchronously, where the SLRD and SLWR signals act directly as strobes, rather than a clock qualifier as in synchronous mode. The signals SLRD, SLWR, SLOE and PKTEND are gated by the signal SLCS#. 4.13.3 GPIF and FIFO Clock Rates 4.14.1 Six Control OUT Signals The 100- and 128-pin packages bring out all six Control Output pins (CTL0-CTL5). The 8051 programs the GPIF unit to define the CTL waveforms. The 56-pin package brings out three of these signals, CTL0-CTL2. CTLx waveform edges can be programmed to make transitions as fast as once per clock (20.8 ns using a 48-MHz clock). 4.14.2 Six Ready IN Signals
The 100- and 128-pin packages bring out all six Ready inputs (RDY0-RDY5). The 8051 programs the GPIF unit to test the RDY pins for GPIF branching. The 56-pin package brings out two of these signals, RDY0-1. 4.14.3 Nine GPIF Address OUT Signals
Nine GPIF address lines are available in the 100- and 128-pin packages, GPIFADR[8..0]. The GPIF address lines allow indexing through up to a 512-byte block of RAM. If more address lines are needed, I/O port pins can be used. 4.14.4 Long Transfer Mode
In master mode, the 8051 appropriately sets GPIF transaction count registers (GPIFTCB3, GPIFTCB2, GPIFTCB1, or GPIFTCB0) for unattended transfers of up to 232 transactions. The GPIF automatically throttles data flow to prevent under or overflow until the full number of requested transactions complete. The GPIF decrements the value in these registers to represent the current status of the transaction.
4.15
ECC Generation
An 8051 register bit selects one of two frequencies for the internally supplied interface clock: 30 MHz and 48 MHz. Alternatively, an externally supplied clock of 5 MHz-48 MHz feeding the IFCLK pin can be used as the interface clock. IFCLK can be configured to function as an output clock when the GPIF and FIFOs are internally clocked. An output enable bit in the IFCONFIG register turns this clock output off, if desired. Another bit within the IFCONFIG register will invert the IFCLK signal whether internally or externally sourced.
The EZ-USB FX1 can calculate ECCs (Error-Correcting Codes) on data that passes across its GPIF or Slave FIFO interfaces. There are two ECC configurations: Two ECCs, each calculated over 256 bytes (SmartMediaTM Standard); and one ECC calculated over 512 bytes. The ECC can correct any one-bit error or detect any two-bit error. Note: To use the ECC logic, the GPIF or Slave FIFO interface must be configured for byte-wide operation. 4.15.1 ECC Implementation
4.14
GPIF
The two ECC configurations are selected by the ECCM bit: 4.15.1.1 ECCM = 0 Two 3-byte ECCs, each calculated over a 256-byte block of data. This configuration conforms to the SmartMedia Standard. Write any value to ECCRESET, then pass data across the GPIF or Slave FIFO interface. The ECC for the first 256 bytes of data will be calculated and stored in ECC1. The ECC for the next 256 bytes will be stored in ECC2. After the second ECC is calculated, the values in the ECCx registers will not change until ECCRESET is written again, even if more data is subsequently passed across the interface. 4.15.1.2 ECCM=1 One 3-byte ECC calculated over a 512-byte block of data. Write any value to ECCRESET then pass data across the GPIF or Slave FIFO interface. The ECC for the first 512 bytes of data will be calculated and stored in ECC1; ECC2 is unused. After the ECC is calculated, the value in ECC1 will not change
The GPIF is a flexible 8- or 16-bit parallel interface driven by a user-programmable finite state machine. It allows the CY7C64713/4 to perform local bus mastering, and can implement a wide variety of protocols such as ATA interface, printer parallel port, and Utopia. The GPIF has six programmable control outputs (CTL), nine address outputs (GPIFADRx), and six general-purpose ready inputs (RDY). The data bus width can be 8 or 16 bits. Each GPIF vector defines the state of the control outputs, and determines what state a ready input (or multiple inputs) must be before proceeding. The GPIF vector can be programmed to advance a FIFO to the next data value, advance an address, etc. A sequence of the GPIF vectors make up a single waveform that will be executed to perform the desired data move between the FX1 and the external device.

until ECCRESET is written again, even if more data is subsequently passed across the interface 4.18.2 I2C Interface Boot Load Access At power-on reset the I2C interface boot loader will load the VID/PID/DID configuration bytes and up to 16 KBytes of program/data. The available RAM spaces are 16 KBytes from 0x0000-0x3FFF and 512 bytes from 0xE000-0xE1FF. The 8051 will be in reset. I2C interface boot loads only occur after power-on reset. 4.18.3 I2C Interface General Purpose Access
4.16
USB Uploads and Downloads
The core has the ability to directly edit the data contents of the internal 16 KByte RAM and of the internal 512-byte scratch pad RAM via a vendor-specific command. This capability is normally used when "soft" downloading user code and is available only to and from internal RAM, only when the 8051 is held in reset. The available RAM spaces are 16 KBytes from 0x0000-0x3FFF (code/data) and 512 bytes from 0xE000-0xE1FF (scratch pad data RAM).[6]
The 8051 can control peripherals connected to the I2C bus using the I2CTL and I2DAT registers. FX1 provides I2C master control only, it is never an I2C slave.
4.17
Autopointer Access
FX1 provides two identical autopointers. They are similar to the internal 8051 data pointers, but with an additional feature: they can optionally increment after every memory access. This capability is available to and from both internal and external RAM. The autopointers are available in external FX1 registers, under control of a mode bit (AUTOPTRSETUP.0). Using the external FX1 autopointer access (at 0xE67B - 0xE67C) allows the autopointer to access all RAM, internal and external to the part. Also, the autopointers can point to any FX1 register or endpoint buffer space. When autopointer access to external memory is enabled, location 0xE67B and 0xE67C in XDATA and code space cannot be used.
4.19 Compatible with Previous Generation EZ-USB FX2
The EZ-USB FX1 is fit/form/function-upgradable to the EZUSB FX2LP. This makes for a easy transition for designers wanting to upgrade their systems from full-speed to the highspeed designs. The pinout and package selection are identical, and all of the firmware developed for the FX1 will function in the FX2LP with proper addition of High Speed descriptors and speed switching code.

I2C Controller
FX1 has one I2C port that is driven by two internal controllers, one that automatically operates at boot time to load VID/PID/DID and configuration information, and another that the 8051, once running, uses to control external I2C devices. The I2C port operates in master mode only. 4.18.1 I2CI2C Port Pins
Figure 5-1 identifies all signals for the three package types. The following pages illustrate the individual pin diagrams, plus a combination diagram showing which of the full set of signals are available in the 128-, 100-, and 56-pin packages. The signals on the left edge of the 56-pin package in Figure 51 are common to all versions in the FX1 family. Three modes are available in all package versions: Port, GPIF master, and Slave FIFO. These modes define the signals on the right edge of the diagram. The 8051 selects the interface mode using the IFCONFIG[1:0] register bits. Port mode is the power-on default configuration. The 100-pin package adds functionality to the 56-pin package by adding these pins: * PORTC or alternate GPIFADR[7:0] address signals * PORTE or alternate GPIFADR[8] address signal and seven additional 8051 signals * Three GPIF Control signals * Four GPIF Ready signals * Nine 8051 signals (two USARTs, three timer inputs, INT4,and INT5#) * BKPT, RD#, WR#. The 128-pin package adds the 8051 address and data buses plus control signals. Note that two of the required signals, RD# and WR#, are present in the 100-pin version. In the 100-pin and 128-pin versions, an 8051 control bit can be set to pulse the RD# and WR# pins when the 8051 reads from/writes to PORTC.

8051 Data Bus. This bidirectional bus is high-impedance when inactive, input for bus reads, and output for bus writes. The data bus is used for external 8051 program and data memory. The data bus is active only for external bus accesses, and is driven LOW in suspend.
Program Store Enable. This active-LOW signal indicates an 8051 code fetch from external memory. It is active for program memory fetches from 0x4000-0xFFFF when the EA pin is LOW, or from 0x0000-0xFFFF when the EA pin is HIGH. Breakpoint. This pin goes active (HIGH) when the 8051 address bus matches the BPADDRH/L registers and breakpoints are enabled in the BREAKPT register (BPEN = 1). If the BPPULSE bit in the BREAKPT register is HIGH, this signal pulses HIGH for eight 12-/24-/48-MHz clocks. If the BPPULSE bit is LOW, the signal remains HIGH until the 8051 clears the BREAK bit (by writing 1 to it) in the BREAKPT register.

Default
Description Interface Clock, used for synchronously clocking data into or out of the slave FIFOs. IFCLK also serves as a timing reference for all slave FIFO control signals and GPIF. When internal clocking is used (IFCONFIG.7 = 1) the IFCLK pin can be configured to output 30/48 MHz by bits IFCONFIG.5 and IFCONFIG.6. IFCLK may be inverted, whether internally or externally sourced, by setting the bit IFCONFIG.4 =1. INT4 is the 8051 INT4 interrupt request input signal. The INT4 pin is edgesensitive, active HIGH. INT5# is the 8051 INT5 interrupt request input signal. The INT5 pin is edgesensitive, active LOW. T2 is the active-HIGH T2 input signal to 8051 Timer2, which provides the input to Timer2 when C/T2 = 1. When C/T2 = 0, Timer2 does not use this pin. T1 is the active-HIGH T1 signal for 8051 Timer1, which provides the input to Timer1 when C/T1 is 1. When C/T1 is 0, Timer1 does not use this bit. T0 is the active-HIGH T0 signal for 8051 Timer0, which provides the input to Timer0 when C/T0 is 1. When C/T0 is 0, Timer0 does not use this bit. RXD1is an active-HIGH input signal for 8051 UART1, which provides data to the UART in all modes. TXD1is an active-HIGH output pin from 8051 UART1, which provides the output clock in sync mode, and the output data in async mode. RXD0 is the active-HIGH RXD0 input to 8051 UART0, which provides data to the UART in all modes. TXD0 is the active-HIGH TXD0 output from 8051 UART0, which provides the output clock in sync mode, and the output data in async mode. CS# is the active-LOW chip select for external memory. WR# is the active-LOW write strobe output for external memory. RD# is the active-LOW read strobe output for external memory. OE# is the active-LOW output enable for external memory. Reserved.

There is no specific timing requirement that needs to be met for asserting PKTEND pin with regards to asserting SLWR. PKTEND can be asserted with the last data value clocked into
the FIFOs or thereafter. The only consideration is that the setup time tSPE and the hold time tPEH for PKTEND must be met. Although typically there are no specific timing requirements for asserting PKTEND in relation to SLWR, there exists a specific Page 38 of 50

CY7C64713/14
corner case condition that needs attention. While using the PKTEND to commit a one byte/word packet, an additional timing requirement needs to be met when the FIFO is configured to operate in auto mode and it is desired to send two packets back to back: * A full packet (full defined as the number of bytes in the FIFO meeting the level set in AUTOINLEN register) committed automatically followed by * A short one byte/word packet committed manually using the PKTEND pin. In this particular scenario, the developer must make sure to assert PKTEND at least one clock cycle after the rising edge that caused the last byte/word to be clocked into the previous auto committed packet. Figure 10-10 below shows this scenario. X is the value the AUTOINLEN register is set to when the IN endpoint is configured to be in auto mode. Figure 10-10 shows a scenario where two packets are being committed. The first packet gets comitted automatically when the number of bytes in the FIFO reaches X (value set in AUTOINLEN register) and the second one byte/word short packet being committed manually using PKTEND. Note that there is atleast one IFCLK cycle timing between asserting PKTEND and clocking of the last byte of the previous packet (causing the packet to be committed automatically). Failing to adhere to this timing, will result in the FX2 failing to send the one byte/word short packet.

Figure 10-17. Slave FIFO Synchronous Sequence of Events Diagram Figure 10-16 shows the timing relationship of the SLAVE FIFO signals during a synchronous FIFO read using IFCLK as the synchronizing clock. The diagram illustrates a single read followed by a burst read. * At t = 0 the FIFO address is stable and the signal SLCS is asserted (SLCS may be tied low in some applications). Note: tSFA has a minimum of 25 nsec. This means when IFCLK is running at 48 MHz, the FIFO address setup time is more than one IFCLK cycle. * At = 1, SLOE is asserted. SLOE is an output enable only, whose sole function is to drive the data bus. The data that is driven on the bus is the data that the internal FIFO pointer is currently pointing to. In this example it is the first data value in the FIFO. Note: the data is pre-fetched and is driven on the bus when SLOE is asserted. * At t = 2, SLRD is asserted. SLRD must meet the setup time of tSRD (time from asserting the SLRD signal to the rising edge of the IFCLK) and maintain a minimum hold time of tRDH (time from the IFCLK edge to the de-assertion of the SLRD signal). If the SLCS signal is used, it must be asserted with SLRD, or before SLRD is asserted (i.e. the SLCS and SLRD signals must both be asserted to start a valid read condition). * The FIFO pointer is updated on the rising edge of the IFCLK, while SLRD is asserted. This starts the propagation of data from the newly addressed location to the data bus. After a propagation delay of tXFD (measured from the rising edge of IFCLK) the new data value is present. N is the first data value read from the FIFO. In order to have data on the FIFO data bus, SLOE MUST also be asserted. The same sequence of events are shown for a burst read and are marked with the time indicators of T=0 through 5. Note: For the burst mode, the SLRD and SLOE are left asserted during the entire duration of the read. In the burst read mode, when SLOE is asserted, data indexed by the FIFO pointer is on the data bus. During the first read cycle, on the rising edge of the clock the FIFO pointer is updated and increments to point to address N+1. For each subsequent rising edge of IFCLK, while the SLRD is asserted, the FIFO pointer is incremented and the next data value is placed on the data bus.

Figure 10-18. Slave FIFO Synchronous Write Sequence and Timing Diagram[17] The Figure 10-18 shows the timing relationship of the SLAVE FIFO signals during a synchronous write using IFCLK as the synchronizing clock. The diagram illustrates a single write followed by burst write of 3 bytes and committing all 4 bytes as a short packet using the PKTEND pin. * At t = 0 the FIFO address is stable and the signal SLCS is asserted. (SLCS may be tied low in some applications) Note: tSFA has a minimum of 25 ns. This means when IFCLK is running at 48 MHz, the FIFO address setup time is more than one IFCLK cycle. * At t = 1, the external master/peripheral must outputs the data value onto the data bus with a minimum set up time of tSFD before the rising edge of IFCLK. * At t = 2, SLWR is asserted. The SLWR must meet the setup time of tSWR (time from asserting the SLWR signal to the rising edge of IFCLK) and maintain a minimum hold time of tWRH (time from the IFCLK edge to the de-assertion of the SLWR signal). If SLCS signal is used, it must be asserted with SLWR or before SLWR is asserted. (i.e. the SLCS and SLWR signals must both be asserted to start a valid write condition). * While the SLWR is asserted, data is written to the FIFO and on the rising edge of the IFCLK, the FIFO pointer is incremented. The FIFO flag will also be updated after a delay of tXFLG from the rising edge of the clock. The same sequence of events are also shown for a burst write and are marked with the time indicators of T=0 through 5. Note: For the burst mode, SLWR and SLCS are left asserted for the entire duration of writing all the required data values. In this burst write mode, once the SLWR is asserted, the data on the FIFO data bus is written to the FIFO on every rising edge of IFCLK. The FIFO pointer is updated on each rising edge of IFCLK. In Figure 10-18, once the four bytes are written to the FIFO, SLWR is de-asserted. The short 4-byte packet can be committed to the host by asserting the PKTEND signal. There is no specific timing requirement that needs to be met for asserting PKTEND signal with regards to asserting the SLWR signal. PKTEND can be asserted with the last data value or thereafter. The only consideration is the setup time tSPE and the hold time tPEH must be met. In the scenario of Figure 10-18, the number of data values committed includes the last value written to the FIFO. In this example, both the data value and the PKTEND signal are clocked on the same rising edge of IFCLK. PKTEND can be asserted in subsequent clock cycles. The FIFOADDR lines should be held constant during the PKTEND assertion. Although there are no specific timing requirement for asserting PKTEND, there is a specific corner case condition that needs attention while using the PKTEND to commit a one byte/word packet. Additional timing requirements exists when the FIFO is configured to operate in auto mode and it is desired to send two packets: a full packet (full defined as the number of bytes in the FIFO meeting the level set in AUTOINLEN register) committed automatically followed by a short one byte/word packet committed manually using the PKTEND pin. In this case, the external master must make sure to assert the PKTEND pin atleast one clock cycle after the rising edge that caused the last byte/word to be clocked into the previous auto committed packet ( the packet with the number of bytes equal to what is set in the AUTOINLEN register). Refer to section 1010 for further details on this timing.

Figure 10-20. Slave FIFO Asynchronous Read Sequence of Events Diagram Figure 10-19 diagrams the timing relationship of the SLAVE FIFO signals during an asynchronous FIFO read. It shows a single read followed by a burst read. * At t = 0 the FIFO address is stable and the SLCS signal is asserted. * At t = 1, SLOE is asserted. This results in the data bus being driven. The data that is driven on to the bus is previous data, it data that was in the FIFO from a prior read cycle. * At t = 2, SLRD is asserted. The SLRD must meet the minimum active pulse of tRDpwl and minimum de-active pulse width of tRDpwh. If SLCS is used then, SLCS must be in asserted with SLRD or before SLRD is asserted. (i.e. the SLCS and SLRD signals must both be asserted to start a valid read condition.) * The data that will be driven, after asserting SLRD, is the updated data from the FIFO. This data is valid after a propagation delay of tXFD from the activating edge of SLRD. In Figure 10-19, data N is the first valid data read from the FIFO. For data to appear on the data bus during the read cycle (i.e. SLRD is asserted), SLOE MUST be in an asserted state. SLRD and SLOE can also be tied together. The same sequence of events is also shown for a burst read marked with T = 0 through 5. Note: In burst read mode, during SLOE is assertion, the data bus is in a driven state and outputs the previous data. Once SLRD is asserted, the data from the FIFO is driven on the data bus (SLOE must also be asserted) and then the FIFO pointer is incremented.

Figure 10-21. Slave FIFO Asynchronous Write Sequence and Timing Diagram[17] Figure 10-21 diagrams the timing relationship of the SLAVE FIFO write in an asynchronous mode. The diagram shows a single write followed by a burst write of 3 bytes and committing the 4-byte-short packet using PKTEND. *At t = 0 the FIFO address is applied, insuring that it meets the setup time of tSFA. If SLCS is used, it must also be asserted (SLCS may be tied low in some applications). *At t = 1 SLWR is asserted. SLWR must meet the minimum active pulse of tWRpwl and minimum de-active pulse width of tWRpwh. If the SLCS is used, it must be in asserted with SLWR or before SLWR is asserted. *At t = 2, data must be present on the bus tSFD before the de-asserting edge of SLWR. *At t = 3, deasserting SLWR will cause the data to be written from the data bus to the FIFO and then increments the FIFO pointer. The FIFO flag is also updated after tXFLG from the de-asserting edge of SLWR. The same sequence of events are shown for a burst write and is indicated by the timing marks of T = 0 through 5. Note: In the burst write mode, once SLWR is deasserted, the data is written to the FIFO and then the FIFO pointer is incremented to the next byte in the FIFO. The FIFO pointer is post incremented. In Figure 10-21 once the four bytes are written to the FIFO and SLWR is deasserted, the short 4-byte packet can be committed to the host using the PKTEND. The external device should be designed to not assert SLWR and the PKTEND signal at the same time. It should be designed to assert the PKTEND after SLWR is deasserted and met the minimum deasserted pulse width. The FIFOADDR lines are to be held constant during the PKTEND assertion.

13.0 Quad Flat Package No Leads (QFN) Package Design Notes
Electrical contact of the part to the Printed Circuit Board (PCB) is made by soldering the leads on the bottom surface of the package to the PCB. Hence, special attention is required to the heat transfer area below the package to provide a good thermal bond to the circuit board. A Copper (Cu) fill is to be designed into the PCB as a thermal pad under the package. Heat is transferred from the FX1 through the device's metal paddle on the bottom side of the package. Heat from here, is conducted to the PCB at the thermal pad. It is then conducted from the thermal pad to the PCB inner ground plane by a 5 x 5 array of via. A via is a plated through hole in the PCB with a finished diameter of 13 mil. The QFN's metal die paddle must be soldered to the PCB's thermal pad. Solder mask is placed on the board top side over each via to resist solder flow into the via. The mask on the top side also minimizes outgassing during the solder reflow process.
For further information on this package design please refer to the application note Surface Mount Assembly of AMKOR's MicroLeadFrame (MLF) Technology. This application note can be downloaded from AMKOR's website from the following URL http://www.amkor.com/products/notes_papers/MLF_AppNote _0902.pdf. The application note provides detailed information on board mounting guidelines, soldering flow, rework process, etc. Figure 13-1 below displays a cross-sectional area underneath the package. The cross section is of only one via. The solder paste template needs to be designed to allow at least 50% solder coverage. The thickness of the solder paste template should be 5 mil. It is recommended that "No Clean" type 3 solder paste is used for mounting the part. Nitrogen purge is recommended during reflow.
