This document describes pertinent features and functions characteristics of the MCF5275 family. The MCF5275 family includes the MCF5275, MCF5275L, MCF5274 and MCF5274L microprocessors. The differences between these parts are summarized in Table 1. This document is written from the perspective of the MCF5275 and unless otherwise noted, the information applies also to the MCF5275L, MCF5274 and MCF5274L. The MCF5275 family delivers a new level of performance and integration on the popular version 2 ColdFire core with up to 159 (Dhrystone 2.1) MIPS @ 166MHz. These highly integrated microprocessors build upon the widely used peripheral mix on the popular MCF5272 ColdFire microprocessor (10/100 Mbps Ethernet MAC and USB device) by adding a second 10/100 Mbps Ethernet MAC (MCF5274 and MCF5275) and hardware encryption (MCF5275L and MCF5275). © Freescale Semiconductor, Inc., 2006.

For a more detailed discussion of the MCF5275 signals, consult the MCF5275 Reference Manual (MCF5275RM). Table 2 lists the signals for the MCF5275 in functional group order. The “Dir” column is the direction for the primary function of the pin. Refer to Section 6, “Mechanicals/Pinouts,” for package diagrams. 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.

The GPIO module is not responsible for assigning these pins. 5 Design Recommendations 5.1 Layout • • • Use a 4-layer printed circuit board with the VDD and GND pins connected directly to the power and ground planes for the MCF5275. See application note AN1259 System Design and Layout Techniques for Noise Reduction in MCU-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 MCF5275 Integrated Microprocessor Family Hardware Specification, Rev. 2 Freescale Semiconductor Preliminary—Subject to Change Without Notice 9 Design Recommendations 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. 5.2 • Power Supply 33uF, 0.1 µF, and 0.01 µF across each power supply 5.2.1 Supply Voltage Sequencing and Separation Cautions DC Power Supply Voltage Figure 2 shows situations in sequencing the I/O VDD (OVDD), SDRAM VDD (SDVDD), PLL VDD (PLLVDD), and Core VDD (VDD). OVDD, SDVDD 3.3V Supplies Stable 2.5V 1.5V SDVDD (2.5V) VDD, PLLVDD 1 2 0 Time Notes: 1. VDD should not exceed OVDD, SDVDD or PLLVDD by more than 0.4 V at any time, including power-up. 2. Recommended that VDD/PLLVDD should track OVDD/SDVDD up to 0.9 V, then separate for completion of ramps. 3. Input voltage must not be greater than the supply voltage (OVDD, SDVDD, VDD, or PLLVDD) by more than 0.5 V at any time, including during power-up. 4. Use 1 ms or slower rise time for all supplies. Figure 2. Supply Voltage Sequencing and Separation Cautions The relationship between SDVDD and OVDD is non-critical during power-up and power-down sequences. Both SDVDD (2.5V or 3.3V) and OVDD are specified relative to VDD. 5.2.1.1 Power Up Sequence If OVDD/SDVDD are powered up with VDD at 0 V, then the sense circuits in the I/O pads will cause all pad output drivers connected to the OVDD/SDVDD to be in a high impedance state. There is no limit on how long after OVDD/SDVDD powers up before VDD must powered up. VDD should not lead the OVDD, SDVDD or PLLVDD by more than 0.4 V during power ramp-up, or there will be high current in the internal ESD protection diodes. The rise times on the power supplies should be slower than 1 µs to avoid turning on the internal ESD protection clamp diodes. The recommended power up sequence is as follows: 1. Use 1 µs or slower rise time for all supplies. MCF5275 Integrated Microprocessor Family Hardware Specification, Rev. 2 10 Preliminary—Subject to Change Without Notice Freescale Semiconductor Design Recommendations 2. VDD/PLLVDD and OVDD/SDVDD should track up to 0.9 V, then separate for the completion of ramps with OVDD/SD VDD going to the higher external voltages. One way to accomplish this is to use a low drop-out voltage regulator. 5.2.1.2 Power Down Sequence If VDD/PLLVDD are powered down first, then sense circuits in the I/O pads will cause all output drivers to be in a high impedance state. There is no limit on how long after VDD and PLLVDD power down before OVDD or SDVDD must power down. VDD should not lag OVDD, SDVDD, or PLLVDD going low by more than 0.4 V during power down or there will be undesired high current in the ESD protection diodes. There are no requirements for the fall times of the power supplies. The recommended power down sequence is as follows: 1. Drop VDD/PLLVDD to 0 V. 2. Drop OVDD/SDVDD supplies. 5.3 • • 5.4 • 5.5 • 5.6 • • • • • • • • Decoupling Place the decoupling capacitors as close to the pins as possible, but they can be outside the footprint of the package. 0.1 µF and 0.01 µF at each supply input 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 electricals. Pull-up Recommendations Use external pull-up resistors on unused inputs. See pin table. 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.

Table 3. Synchronous DRAM Signal Connections Signal Description SD_SRAS 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 SDRAM_CS[1:0], which should not be interfaced to the SDRAM SD_SRAS signals. SD_SCAS 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. SD_WE DRAM read/write. Asserted for write operations and negated for read operations. SD_CS[1:0] Row address strobe. Select each memory block of SDRAMs connected to the MCF5275. One SDRAM_CS signal selects one SDRAM block and connects to the corresponding CS signals. SD_CKE 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. BS[3:2] Column address strobe. For synchronous operation, BS[3:2] function as byte enables to the SDRAMs. They connect to the DQM signals (or mask qualifiers) of the SDRAMs. DDR_CLKOUT 5.7.1.2 Bus clock output. Connects to the CLK input of SDRAMs. Address Multiplexing See the SDRAM controller module chapter in the MCF5275 Reference Manual for details on address multiplexing. 5.7.2 Ethernet PHY Transceiver Connection The FEC supports both an MII interface for 10/100 Mbps Ethernet and a seven-wire serial interface for 10 Mbps Ethernet. The interface mode is selected by R_CNTRL[MII_MODE]. In MII mode, the 802.3 standard defines and the FEC module supports 18 signals. These are shown in Table 4. Table 4.

This section contains detailed information on power considerations, DC/AC electrical characteristics, and AC timing specifications of MCF5275. 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 appendix supersede any values found in the module specifications. 8.1 Maximum Ratings Table 7.

Absolute Maximum Ratings are stress ratings only, and functional operation at the maxima is not guaranteed. Stress beyond those listed may affect device reliability or cause permanent damage to the device. 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 O VDD). 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. All functional non-supply pins are internally clamped to VSS and O VDD. Power supply must maintain regulation within operating O VDD range during instantaneous and operating maximum current conditions. If positive injection current (Vin > O VDD) is greater than IDD, the injection current may flow out of O VDD and could result in external power supply going out of regulation. Insure external O VDD load will shunt current greater than maximum injection current. This will be the greatest risk when the MCU is not consuming power (ex; no clock).Power supply must maintain regulation within operating VDD range during instantaneous and operating maximum current conditions.

Freescale recommends the use of θJmA and power dissipation specifications in the system design to prevent device junction temperatures from exceeding the rated specification. System designers should be aware that device junction temperatures can be significantly influenced by board layout and surrounding devices. Conformance to the device junction temperature specification can be verified by physical measurement in the customer’s system using the Ψjt parameter, the device power dissipation, and the method described in EIA/JESD Standard 51-2. 2 Per JEDEC JESD51-6 with the board horizontal. 3 Thermal resistance between the die and the printed circuit board in conformance with JEDEC JESD51-8. Board temperature is measured on the top surface of the board near the package. 4 Thermal resistance between the die and the case top surface as measured by the cold plate method (MIL SPEC-883 Method 1012.1). 1 MCF5275 Integrated Microprocessor Family Hardware Specification, Rev. 2 Freescale Semiconductor Preliminary—Subject to Change Without Notice 19 Preliminary Electrical Characteristics 5 Thermal characterization parameter indicating the temperature difference between package top and the junction temperature per JEDEC JESD51-2. When Greek letters are not available, the thermal characterization parameter is written in conformance with Psi-JT. The average chip-junction temperature (TJ) in °C can be obtained from: T J = T A + ( P D × Θ JMA ) (1) Where: TA = Ambient Temperature, °C ΘJMA = Package Thermal Resistance, Junction-to-Ambient, °C/W PD = PINT + PI/O PINT = IDD × VDD, Watts - Chip Internal Power PI/O = Power Dissipation on Input and Output Pins — User Determined For most applications PI/O < PINT and can be ignored. An approximate relationship between PD and TJ (if PI/O is neglected) is: P D = K ÷ ( T J + 273°C ) (2) Solving equations 1 and 2 for K gives: K = PD × (TA + 273 °C) + ΘJMA × 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. 8.3 ESD Protection Table 9.

The specifications numbers assume no parallel termination. 5 Refer to the MCF5274 signals chapter for pins having weak internal pull-up devices. 6 This parameter is characterized before qualification rather than 100% tested. 7 pF load ratings are based on DC loading and are provided as an indication of driver strength. High speed interfaces require transmission line analysis to determine proper drive strength and termination. 8 Current measured at maximum system clock frequency, all modules active, and default drive strength with matching load. 9 All functional non-supply pins are internally clamped to VSS and their respective VDD. 10 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. 11 Power supply must maintain regulation within operating VDD 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 MCU 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. 8.5 Oscillator and Phase Lock Loop (PLLMRFM) Electrical Specifications Table 11.

All internal registers retain data at 0 Hz. “Loss of Reference Frequency” is the reference frequency detected internally, which transitions the PLL into self clocked mode. Self clocked mode frequency is the frequency that the PLL operates at when the reference frequency falls below fLOR with default MFD/RFD settings. This parameter is guaranteed by characterization before qualification rather than 100% tested. Proper PC board layout procedures must be followed to achieve specifications. Load Capacitance determined from crystal manufacturer specifications and will include circuit board parasitics. 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 VDDPLL 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 τ) x Tref, where Tref = 1/Fref_crystal = 1/Fref_ext = 1/Fref_1:1, and τ = 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 VDDPLL and VSSPLL and variation in crystal oscillator frequency increase the jitter percentage for a given interval. Based on slow system clock of 33MHz maximum frequency. Modulation percentage applies over an interval of 10µs, 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) External Interface Timing Characteristics Table 12 lists processor bus input timings. 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 reference clock is the CLKOUT output. All other timing relationships can be derived from these values.

DDR_CLKOUT operates at half the frequency of the PLLMRFM output and the ColdFire core. tCKH + tCKL must be less than or equal to tCK. D[31:24] is relative to SD_DQS3 and D[23:16] is relative to SD_DQS2. The first data beat will be valid before the first rising edge of SD_DQS and after the SD_DQS write preamble. The remaining data beats will be valid for each subsequent SD_DQS edge Data input skew is derived from each SD_DQS clock edge. It begins with a SD_DQS transition and ends when the last data line becomes valid. This input skew must include DDR memory output skew and system level board skew (due to routing or other factors). Data input hold is derived from each SD_DQS clock edge. It begins with a SD_DQS transition and ends when the first data line becomes invalid. Figure 13 shows a DDR SDRAM write cycle.

The I2C interface is designed to scale the actual data transition time to move it to the middle of the I2C_SCL low period. The actual position is affected by the prescale and division values programmed into the IFDR; however, the numbers given in Table 24 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.
