Hardware Design Considerations
3.1
PLL Power Filtering
To further enhance noise isolation, an external filter is strongly recommended for PLL analog VDD pins. The filter shown in
Figure 1 should be connected between the board VDD and the PLLVDD pins. The resistor and capacitors should be placed as
close to the dedicated PLLVDD pin as possible.

3.2
USB Power Filtering
To minimize noise, external filters are required for each of the USB power pins. The filter shown in Figure 2 should be
connected between the board EVDD or IVDD and each of the USBVDD pins. The resistor and capacitors should be placed as
close to the dedicated USBVDD pin as possible.

NOTE
In addition to the above filter circuitry, a 0.01 F capacitor is also recommended in parallel
with those shown.
3.3
Supply Voltage Sequencing and Separation Cautions
The relationship between SDVDD and EVDD is non-critical during power-up and power-down sequences. SDVDD (2.5V or
3.3V) and EVDD are specified relative to IVDD.
3.3.1
Power Up Sequence
If EVDD/SDVDD are powered up with IVDD at 0 V, the sense circuits in the I/O pads cause all pad output drivers connected to
the EVDD/SDVDD to be in a high impedance state. There is no limit on how long after EVDD/SDVDD powers up before IVDD
must powered up. IVDD should not lead the EVDD, SDVDD, or PLLVDD by more than 0.4 V during power ramp-up or there is
high current in the internal ESD protection diodes. The rise times on the power supplies should be slower than 500 us to avoid
turning on the internal ESD protection clamp diodes.
3.3.2
Power Down Sequence
If IVDD/PLLVDD are powered down first, 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 IVDD and PLLVDD power down before EVDD or SDVDD must power down. IVDD should
not lag EVDD, SDVDD, or PLLVDD going low by more than 0.4 V during power down or there is 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.
2.
Drop IVDD/PLLVDD to 0 V.
Drop EVDD/SDVDD supplies.

Signal Multiplexing
The following table lists all the MCF537x pins grouped by function. The Dir column is the direction for the primary function
of the pin only. Refer to Section 7, “Package Information,” for package diagrams. For a more detailed discussion of the
MCF537x signals, consult the MCF5373 Reference Manual (MCF5373RM).
NOTE
In this table and throughout this document, a single signal within a group is designated
without square brackets (i.e., A23), 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 default to their GPIO functionality.

Refers to pin’s primary function.
Pull-up enabled internally on this signal for this mode.
The SDRAM functions of these signals are not programmable by the user. They are dynamically switched by the processor
when accessing SDRAM memory space and are included here for completeness.
Primary functionality selected by asserting the DRAMSEL signal (SDR mode). Alternate functionality selected by negating the
DRAMSEL signal (DDR mode). The GPIO module is not responsible for assigning these pins.
GPIO functionality is determined by the edge port module. The GPIO module is only responsible for assigning the alternate
functions.
If JTAG_EN is asserted, these pins default to Alternate 1 (JTAG) functionality. The GPIO module is not responsible for assigning
these pins.
Pull-down enabled internally on this signal for this mode.

Electrical Characteristics
This document contains electrical specification tables and reference timing diagrams for the MCF5373 microcontroller unit.
This section contains detailed information on power considerations, DC/AC electrical characteristics, and AC timing
specifications of MCF5373.
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 MCU document supersede any values found in the module
specifications.

Functional operating conditions are given in Section 5.4, “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 (VSS or
EVDD).
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,
and then use the larger of the two values.
All functional non-supply pins are internally clamped to VSS and EVDD.
Power supply must maintain regulation within operating EVDD range during instantaneous and
operating maximum current conditions. If positive injection current (Vin > EVDD) is greater than
IDD, the injection current may flow out of EVDD and could result in external power supply going
out of regulation. Ensure external EVDD load shunts current greater than maximum injection
current. This is the greatest risk when the MCU is not consuming power (ex; no clock). Power
supply must maintain regulation within operating EVDD 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.
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.
Thermal resistance between the die and the case top surface as measured by the cold plate method (MIL SPEC-883
Method 1012.1).
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 )

For most applications PI/O < PINT and can be ignored. An approximate relationship between PD and TJ (if PI/O is neglected) is:
K
P D = --------------------------------( T J + 273°C )
Eqn. 2
Solving equations 1 and 2 for K gives:
2
K = P D × ( T A × 273°C ) + Q JMA × P D
Eqn. 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 Equation 1 and Equation 2 iteratively
for any value of TA.

PCB_EXTAL and CPCB_XTAL are the measured PCB stray capacitances on EXTAL and XTAL, respectively.
8 Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum f
sys.
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 PLL VDD, EVDD, and VSS and variation in crystal oscillator frequency increase
the Cjitter percentage for a given interval.
9 Values are with frequency modulation disabled. If frequency modulation is enabled, jitter is the sum of Cjitter+Cmod.
10 Modulation percentage applies over an interval of 10 μs, or equivalently the modulation rate is 100 KHz.

FlexBus
A multi-function external bus interface called FlexBus is provided with basic functionality to interface to slave-only devices up
to a maximum bus frequency of 80MHz. It can be directly connected to asynchronous or synchronous devices such as external
boot ROMs, flash memories, gate-array logic, or other simple target (slave) devices with little or no additional circuitry. For
asynchronous devices a simple chip-select based interface can be used. The FlexBus interface has six general purpose
chip-selects (FB_CS[5:0]) which can be configured to be distributed between the FlexBus or SDRAM memory interfaces.
Chip-select, FB_CS0 can be dedicated to boot ROM access and can be programmed to be byte (8 bits), word (16 bits), or
longword (32 bits) wide. Control signal timing is compatible with common ROM/flash memories.

The FlexBus supports programming an extension of the address hold. Please consult the Reference Manual
for more information.
NOTE
The processor drives the data lines during the first clock cycle of the transfer
with the full 32-bit address. This may be ignored by standard connected
devices using non-multiplexed address and data buses. However, some
applications may find this feature beneficial.
The address and data busses are muxed between the FlexBus and SDRAM
controller. At the end of the read and write bus cycles the address signals are
indeterminate.

SDRAM Bus
The SDRAM controller supports accesses to main SDRAM memory from any internal master. It supports standard SDRAM or
double data rate (DDR) SDRAM, but it does not support both at the same time.
5.7.1
SDR SDRAM AC Timing Characteristics
The following timing numbers indicate when data is latched or driven onto the external bus, relative to the memory bus clock,
when operating in SDR mode on write cycles and relative to SD_DQS on read cycles. The device’s SDRAM controller is a
DDR controller that has an SDR mode. Because it is designed to support DDR, a DQS pulse must remain supplied to the device
for each data beat of an SDR read. The processor accomplishes this by asserting a signal named SD_SDR_DQS during read
cycles. Care must be taken during board design to adhere to the following guidelines and specs with regard to the
SD_SDR_DQS signal and its usage.

The FlexBus and SDRAM clock operates at the same frequency of the internal bus clock. See the PLL chapter of the MCF5373
Reference Manual for more information on setting the SDRAM clock rate.
SD_CLK is one SDRAM clock in (ns).
Pulse width high plus pulse width low cannot exceed min and max clock period.
Pulse width high plus pulse width low cannot exceed min and max clock period.
SD_DQS is designed to pulse 0.25 clock before the rising edge of the memory clock. This is a guideline only. Subtle variation
from this guideline is expected. SD_DQS only pulses during a read cycle and one pulse occurs for each data beat.
SDR_DQS is designed to pulse 0.25 clock before the rising edge of the memory clock. This spec is a guideline only. Subtle
variation from this guideline is expected. SDR_DQS only pulses during a read cycle and one pulse occurs for each data beat.
The SDR_DQS pulse is designed to be 0.5 clock in width. The timing of the rising edge is most important. The falling edge
does not affect the memory controller.
Because a read cycle in SDR mode uses the DQS circuit within the device, it is most critical that the data valid window be
centered 1/4 clk after the rising edge of DQS. Ensuring that this happens results in successful SDR reads. The input setup
spec is provided as guidance.

SD_CLK is one SDRAM clock in (ns).
Pulse width high plus pulse width low cannot exceed min and max clock period.
Command output valid should be 1/2 the memory bus clock (SD_CLK) plus some minor adjustments for process, temperature,
and voltage variations.
This specification relates to the required input setup time of today’s DDR memories. The processor’s output setup should be
larger than the input setup of the DDR memories. If it is not larger, the input setup on the memory is in violation.
MEM_DATA[31:24] is relative to MEM_DQS[3], MEM_DATA[23:16] is relative to MEM_DQS[2], MEM_DATA[15:8] is relative to
MEM_DQS[1], and MEM_[7:0] is relative MEM_DQS[0].
The first data beat is valid before the first rising edge of DQS and after the DQS write preamble. The remaining data beats are
valid for each subsequent DQS edge.
This specification relates to the required hold time of today’s DDR memories. MEM_DATA[31:24] is relative to MEM_DQS[3],
MEM_DATA[23:16] is relative to MEM_DQS[2], MEM_DATA[15:8] is relative to MEM_DQS[1], and MEM_[7:0] is relative
MEM_DQS[0].
Data input skew is derived from each DQS clock edge. It begins with a 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 DQS clock edge. It begins with a DQS transition and ends when the first data line
becomes invalid.

for non-inverted serial clock polarity (SSI_TCR[TSCKP] = 0, SSI_RCR[RSCKP] = 0) and a non-inverted frame sync
(SSI_TCR[TFSI] = 0, SSI_RCR[RFSI] = 0). If the polarity of the clock and/or the frame sync have been inverted, all the timings
remain valid by inverting the clock signal (SSI_BCLK) and/or the frame sync (SSI_FS) shown in the figures below.

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 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.
