For a more detailed discussion of the MCF523x signals, consult the MCF5235 Reference Manual (MCF5235RM). 2.1 Signal Properties NOTE In this table and throughout this document a single signal within a group is designated without square brackets (i.e., A24), while designations for multiple signals within a group use brackets (i.e., A[23:21]) and is meant to include all signals within the two bracketed numbers when these numbers are separated by a colon. NOTE The primary functionality of a pin is not necessarily its default functionality. Pins that are muxed with GPIO will default to their GPIO functionality. Table 2. MCF523x Signal Information and Muxing Table 2 lists all of the signals grouped by function. The "Dir" column is the direction for the primary function of the pin.

There are four modes of operation: RUN, WAIT, DOZE, and STOP. The system enters a low power mode when the user programs the low power bits (LPMD) in the LPCR (Low Power Control Register) in the CIM before the CPU core executes a STOP instruction. This idles the CPU with no cycles active. The LPMD bits indicate to the system and clock controller to power down and stop the clocks appropriately. During STOP mode, the system clock is stopped low. A wakeup event is required to exit a low power mode and return back to RUN mode. Wakeup events consist of any of the following conditions. See the following sections for more details. 1. Any type of reset. 2. Assertion of the BKPT pin to request entry into Debug mode. 3. Debug request bit in the BDM control register to request entry into debug mode. 4. Any valid interrupt request. 3.2.1 RUN Mode RUN mode is the normal system operating mode. Current consumption in this mode is related directly to the frequency chosen for the system clock. MCF523x Integrated Microprocessor Hardware Specification, Rev. 1.3 16 Preliminary Freescale Semiconductor Design Recommendations 3.2.2 WAIT Mode WAIT mode is intended to be used to stop only the CPU core and memory clocks until a wakeup event is detected. In this mode, peripherals may be programmed to continue operating and can generate interrupts, which cause the CPU core to exit from WAIT mode. 3.2.3 DOZE Mode DOZE mode affects the CPU core in the same manner as WAIT mode, but with a different code on the CIM LPMD bits, which are monitored by the peripherals. Each peripheral defines individual operational characteristics in DOZE mode. Peripherals which continue to run and have the capability of producing interrupts may cause the CPU to exit the DOZE mode and return to the RUN mode. Peripherals which are stopped will restart operation on exit from DOZE mode as defined for each peripheral. 3.2.4 STOP Mode STOP mode affects the CPU core in the same manner as the WAIT and DOZE modes, but with a different code on the CCM LPMD bits. In this mode, all clocks to the system are stopped and the peripherals cease operation. STOP mode must be entered in a controlled manner to ensure that any current operation is properly terminated. When exiting STOP mode, most peripherals retain their pre-stop status and resume operation. 3.2.5 Peripheral Shut Down Most peripherals may be disabled by software in order to cease internal clock generation and remain in a static state. Each peripheral has its own specific disabling sequence (refer to each peripheral description for further details). A peripheral may be disabled at anytime and will remain disabled during any low power mode of operation. 4 4.1 * * * Design Recommendations Layout Use a 4-layer printed circuit board with the VDD and GND pins connected directly to the power and ground planes for the MCF523x. See application note AN1259 System Design and Layout Techniques for Noise Reduction in processor-Based Systems. Match the PC layout trace width and routing to match trace length to operating frequency and board impedance. Add termination (series or therein) to the traces to dampen reflections. Increase the PCB impedance (if possible) keeping the trace lengths balanced and short. Then do cross-talk analysis to separate traces with significant parallelism or are otherwise "noisy". Use 6 mils trace and separation. Clocks get extra separation and more precise balancing. MCF523x Integrated Microprocessor Hardware Specification, Rev. 1.3 Freescale Semiconductor Preliminary 17 Design Recommendations 4.2 * Power Supply 33 F, .1 F and .01 F across each power supply 4.3 * * Decoupling Place the decoupling caps as close to the pins as possible, but they can be outside the footprint of the package. .1 F and .01 F at each supply input 4.4 * Buffering Use bus buffers on all data/address lines for all off-board accesses and for all on-board accesses when excessive loading is expected. See Section 6, "Preliminary Electrical Characteristics." 4.5 * Pull-up Recommendations Use external pull-up resistors on unused inputs. See pin table. 4.6 * * * * * * * * Clocking Recommendations Use a multi-layer board with a separate ground plane. Place the crystal and all other associated components as close to the EXTAL and XTAL (oscillator pins) as possible. Do not run a high frequency trace around crystal circuit. Ensure that the ground for the bypass capacitors is connected to a solid ground trace. Tie the ground trace to the ground pin nearest EXTAL and XTAL. This prevents large loop currents in the vicinity of the crystal. Tie the ground pin to the most solid ground in the system. Do not connect the trace that connects the oscillator and the ground plane to any other circuit element. This tends to make the oscillator unstable. Tie XTAL to ground when an external oscillator is clocking the device. 4.7 4.7.1 4.7.1.1 Interface Recommendations SDRAM Controller SDRAM Controller Signals in Synchronous Mode Table 4 shows the behavior of SDRAM signals in synchronous mode. MCF523x Integrated Microprocessor Hardware Specification, Rev. 1.3 18 Preliminary Freescale Semiconductor Design Recommendations Table 4. Synchronous DRAM Signal Connections Signal SD_SRAS Description Synchronous row address strobe. Indicates a valid SDRAM row address is present and can be latched by the SDRAM. SD_SRAS should be connected to the corresponding SDRAM SD_SRAS. Do not confuse SD_SRAS with the DRAM controller's SD_CS[1:0], which should not be interfaced to the SDRAM SD_SRAS signals. Synchronous column address strobe. Indicates a valid column address is present and can be latched by the SDRAM. SD_SCAS should be connected to the corresponding signal labeled SD_SCAS on the SDRAM. DRAM read/write. Asserted for write operations and negated for read operations. Row address strobe. Select each memory block of SDRAMs connected to the MCF523x. One SD_CS signal selects one SDRAM block and connects to the corresponding CS signals. Synchronous DRAM clock enable. Connected directly to the CKE (clock enable) signal of SDRAMs. Enables and disables the clock internal to SDRAM. When CKE is low, memory can enter a power-down mode where operations are suspended or they can enter self-refresh mode. SD_CKE functionality is controlled by DCR[COC]. For designs using external multiplexing, setting COC allows SD_CKE to provide command-bit functionality. Column address strobe. For synchronous operation, BS[3:0] function as byte enables to the SDRAMs. They connect to the DQM signals (or mask qualifiers) of the SDRAMs. Bus clock output. Connects to the CLK input of SDRAMs. SD_SCAS DRAMW SD_CS[1:0] SD_CKE BS[3:0] CLKOUT 4.7.1.2 Address Multiplexing Table 5 shows the generic address multiplexing scheme for SDRAM configurations.

To use the tables, find the one that corresponds to the number of column address lines on the SDRAM and to the port size as seen by the MCF523x, which is not necessarily the SDRAM port size. For example, if two 1M x 16-bit SDRAMs together form a 2M x 32-bit memory, the port size is 32 bits. Most SDRAMs likely have fewer address lines than are shown in the tables, so follow only the connections shown until all SDRAM address lines are connected. Table 6.

This section contains detailed information on power considerations, DC/AC electrical characteristics, and AC timing specifications of MCF5235. The electrical specifications are preliminary and are from previous designs or design simulations. These specifications may not be fully tested or guaranteed at this early stage of the product life cycle, however for production silicon these specifications will be met. Finalized specifications will be published after complete characterization and device qualifications have been completed. NOTE The parameters specified in this processor document supersede any values found in the module specifications. 6.1 Maximum Ratings Table 26.

Absolute Maximum Ratings are stress ratings only, and functional operation at the maxima is not guaranteed. Continued operation at these levels may affect device reliability or cause permanent damage to the device. 2 This device contains circuitry protecting against damage due to high static voltage or electrical fields; however, it is advised that normal precautions be taken 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 VSS or OVDD). 3 Input must be current limited to the value specified. To determine the value of the required current-limiting resistor, calculate resistance values for positive and negative clamp voltages, then use the larger of the two values. 4 All functional non-supply pins are internally clamped to V SS and OVDD. 5 Power supply must maintain regulation within operating OV DD range during instantaneous and operating maximum current conditions. If positive injection current (Vin > OVDD) is greater than IDD, the injection current may flow out of OVDD and could result in external power supply going out of regulation. Insure external OVDD load will shunt current greater than maximum injection current. This will be the greatest risk when the processor is not consuming power (ex; no clock).Power supply must maintain regulation within operating OVDD range during instantaneous and operating maximum current conditions. 6.2 Thermal Characteristics Table 27.

An approximate relationship between PD and TJ (if PI/O is neglected) is: P D = K / ( T J + 273C ) (2) Solving equations 1 and 2 for K gives: K = PD x (TA + 273 C) + JMA x PD 2 (3) where K is a constant pertaining to the particular part. K can be determined from equation (3) by measuring PD (at equilibrium) for a known TA. Using this value of K, the values of PD and TJ can be obtained by solving equations (1) and (2) iteratively for any value of TA. 6.3 DC Electrical Specifications Table 28.

High speed interfaces require transmission line analysis to determine proper drive strength and termination. See High Speed Signal Propagation: Advanced Black Magic by Howard W. Johnson for design guidelines. 5 Current measured at maximum system clock frequency, all modules active, and default drive strength with matching load. 6 All functional non-supply pins are internally clamped to V SS and their respective VDD. 7 Input must be current limited to the value specified. To determine the value of the required current-limiting resistor, calculate resistance values for positive and negative clamp voltages, then use the larger of the two values. 8 Power supply must maintain regulation within operating V DD range during instantaneous and operating maximum current conditions. If positive injection current (Vin > VDD) is greater than IDD, the injection current may flow out of VDD and could result in external power supply going out of regulation. Insure external VDD load will shunt current greater than maximum injection current. This will be the greatest risk when the processor is not consuming power. Examples are: if no system clock is present, or if clock rate is very low which would reduce overall power consumption. Also, at power-up, system clock is not present during the power-up sequence until the PLL has attained lock. 6.4 Oscillator and PLLMRFM Electrical Characteristics Table 29.

MCF523x Integrated Microprocessor Hardware Specification, Rev. 1.3 Freescale Semiconductor Preliminary 39 Preliminary Electrical Characteristics 8 9 10 11 12 13 14 15 16 This specification applies to the period required for the PLL to relock after changing the MFD frequency control bits in the synthesizer control register (SYNCR). Assuming a reference is available at power up, lock time is measured from the time VDD and VDDSYN are valid to RSTOUT negating. If the crystal oscillator is being used as the reference for the PLL, then the crystal start up time must be added to the PLL lock time to determine the total start-up time. tlpll = (64 * 4 * 5 + 5 x ) x Tref, where Tref = 1/Fref_crystal = 1/Fref_ext = 1/Fref_1:1, and = 1.57x10-6 x 2(MFD + 2). PLL is operating in 1:1 PLL mode. Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum fsys/2. Measurements are made with the device powered by filtered supplies and clocked by a stable external clock signal. Noise injected into the PLL circuitry via VDDSYN and VSSSYN and variation in crystal oscillator frequency increase the Cjitter percentage for a given interval. Values are with frequency modulation disabled. If frequency modulation is enabled, jitter is the sum of Cjitter+Cmod. Modulation percentage applies over an interval of 10s, or equivalently the modulation rate is 100KHz. Modulation rate selected must not result in fsys/2 value greater than the fsys/2 maximum specified value. Modulation range determined by hardware design. fsys/2 = fico / (2 * 2RFD) 6.5 External Interface Timing Characteristics NOTE All processor bus timings are synchronous; that is, input setup/hold and output delay with respect to the rising edge of a reference clock.

The actual position is affected by the prescale and division values programmed into the IFDR; however, the numbers given in Table 36 are minimum values. 2 Because I2C_SCL and I2C_SDA are open-collector-type outputs, which the processor can only actively drive low, the time I2C_SCL or I2C_SDA take to reach a high level depends on external signal capacitance and pull-up resistor values. 3 Specified at a nominal 50-pF load.

The transmit outputs (ETXD[3:0], ETXEN, ETXER) can be programmed to transition from either the rising or falling edge of ETXCLK, and the timing is the same in either case. This options allows the use of non-compliant MII PHYs. Refer to the Ethernet chapter for details of this option and how to enable it. Table 38.
