MCF523x Integrated
Microprocessor
Hardware Specification
by: Microcontroller Solutions Group
The MCF523x is a family of highly-integrated 32-bit
microcontrollers based on the V2 ColdFire
microarchitecture. Featuring a 16 or 32 channel eTPU,
64 Kbytes of internal SRAM, a 2-bank SDRAM
controller, four 32-bit timers with dedicated DMA, a 4
channel DMA controller, up to 2 CAN modules, 3
UARTs and a queued SPI, the MCF523x family has been
designed for general purpose industrial control
applications. It is also a high-performance upgrade for
users of the MC68332. This document provides an
overview of the MCF523x microcontroller family, as
well as detailed descriptions of the mechanical and
electrical characteristics of the devices.
The MCF523x family is based on the Version 2 ColdFire
reduced instruction set computing (RISC)
microarchitecture operating at a core frequency of up to
150 MHz and bus frequency up to 75 MHz.

Signal Descriptions
This section describes signals that connect off chip, including a table of signal properties. For a more
detailed discussion of the MCF523x signals, consult the MCF5235 Reference Manual (MCF5235RM).
4.1
Signal Properties
Table 2 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
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 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.

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 1. 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.

Design Recommendations
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
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.

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
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.”
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.

SDRAM Controller
5.7.1.1
SDRAM Controller Signals in Synchronous Mode
Table 3 shows the behavior of SDRAM signals in synchronous mode.
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 SD_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.
DRAMW
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 MCF523x. One
SD_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[3:0]
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.
CLKOUT
Bus clock output. Connects to the CLK input of SDRAMs.
5.7.1.2
Address Multiplexing
See the SDRAM controller module chapter in the MCF5235 Reference Manual for details on address
multiplexing.

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.

FlexCAN
The FlexCAN module interface to the CAN bus is composed of 2 pins: CANTX and CANRX, which are
the serial transmitted data and the serial received data. The use of an external CAN transceiver to interface
to the CAN bus is generally required. The transceiver is capable of driving the large current needed for the
CAN bus and has current protection, against a defective CAN bus or defective stations.

Functional operating conditions are given in DC Electrical Specifications. 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.
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).
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 OVDD.
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. 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.

Electrical Characteristics
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.

Refer to Table 10 for additional PLL specifications.
Refer to the MCF5235 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.

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.
