MCF5271 Integrated Microprocessor Hardware Specification
by: Microcontroller Solutions Group
The MCF5271 family is a highly integrated implementation of the ColdFire® family of reduced instruction set computing (RISC) microprocessors. This document describes pertinent features and functions of the MCF5271 family. The MCF5271 family includes the MCF5271 and MCF5270 microprocessors. The differences between these parts are summarized below in Table 1. This document is written from the perspective of the MCF5271 and unless otherwise noted, the information applies also to the MCF5270. The MCF5271 family combines low cost with high integration on the popular version 2 ColdFire core with over 144 (Dhrystone 2.1) MIPS at 150 MHz. Positioned for applications requiring a cost-sensitive 32-bit solution, the MCF5271 family features a 10/100 Ethernet MAC and optional hardware encryption to ensure the application can be connected and protected. In addition, the MCF5271 family features an enhanced multiply accumulate unit (eMAC), large on-chip memory (64 Kbytes SRAM, 8 Kbytes configurable cache), and a 32-bit SDR SDRAM memory controller.

Features Signal Descriptions
For a detailed feature list see the MCF5271 Reference Manual (MCF5271RM).
This section describes signals that connect off chip, including a table of signal properties. For a more detailed discussion of the MCF5271 signals, consult the MCF5271 Reference Manual (MCF5271RM).
4.1
Signal Properties
Table 4 lists all of the signals grouped by function. The “Dir” column is the direction for the primary function of the pin. Refer to Section 6, “Mechanicals/Pinouts and Part Numbers,” 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.

Refers to pin’s primary function. All pins which are configurable for GPIO have a pullup enabled in GPIO mode with the exception of PBUSCTL[7], PBUSCTL[4:0], PADDR, PBS, PSDRAM. 2 If JTAG_EN is asserted, these pins default to Alternate 1 (JTAG) functionality. The GPIO module is not responsible for assigning these pins.

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 MCF5271. 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.

0 Time Notes: 1. VDD should not exceed OVDD or VDDPLL by more than 0.4 V at any time, including power-up. 2. Recommended that VDD should track OVDD/VDDPLL up to 0.9 V, then separate for completion of ramps. 3. Input voltage must not be greater than the supply voltage (OVDD, VDD, or VDDPLL) 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
5.2.1.1
Power Up Sequence
If OVDD is powered up with VDD at 0 V, then the sense circuits in the I/O pads cause all pad output drivers connected to the OVDD to be in a high impedance state. There is no limit on how long after OVDD powers up before VDD must power up. VDD should not lead the OVDD or VDDPLL 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 ms or slower rise time for all supplies. 2. VDD and OVDD/VDDPLL should track up to 0.9 V, then separate for the completion of ramps with OVDD 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 is powered down first, then sense circuits in the I/O pads cause all output drivers to be in a high impedance state. There is no limit on how long after VDD powers down before OVDD/VDDPLL must power down. VDD should not lag OVDD or VDDPLL going low by more than 0.4 V during power down or there

Design Recommendations
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 to 0 V. 2. Drop OVDD/VDDPLL supplies.
5.3
• •
Decoupling
Place the decoupling caps 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
5.4
•
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 7, “Electrical Characteristics.”
5.5
•
Pull-up Recommendations
Use external pull-up resistors on unused inputs. See pin table.
5.6
• • • • • • • •
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.

Table 3. 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 MCF5271. 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.

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 VSS and OVDD. 5 Power supply must maintain regulation within operating OVDD 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.

θJMA and Ψjt parameters are simulated in conformance with EIA/JESD Standard 51-2 for natural convection. Motorola 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. Per JEDEC JESD51-6 with the board horizontal. 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.

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.

Refer to Table 10 for additional PLL specifications. Refer to the MCF5271 signals section for pins having weak internal pull-up devices. This parameter is characterized before qualification rather than 100% tested. 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. See High Speed Signal Propagation: Advanced Black Magic by Howard W. Johnson for design guidelines. Current measured at maximum system clock frequency, all modules active, and default drive strength with matching load. All functional non-supply pins are internally clamped to VSS and their respective 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. 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 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.

All values given are initial design targets and subject to change. 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. 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 τ) Tref, where Tref = 1/Fref_crystal = 1/Fref_ext = 1/Fref_1:1, and τ = 1.57x10-6 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 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)

Note: Output numbers depend on the value programmed into the IFDR; an IFDR programmed with the maximum frequency (IFDR = 0x20) results in minimum output timings as shown in Table 17. 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 17 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.
Figure 15 shows timing for the values in Table 16 and Table 17.
