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 2 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 3 should be
connected between the board EVDD and the USBVDD pin. The resistor and capacitors should be placed as close to the dedicated
USBVDD pin as possible.

ADC Power Filtering
To minimize noise, an external filters is required for the ADCVDD power pin. The filter shown in Figure 4 should be connected
between the board EVDD and the ADCVDD pin. The resistor and capacitors should be placed as close to the dedicated ADCVDD
pin as possible.

Supply Voltage Sequencing
The relationship between SDVDD and EVDD is non-critical during power-up and power-down sequences. Both SDVDD (2.5V
or 3.3V) and EVDD are specified relative to IVDD.
3.4.1
Power Up Sequence
If EVDD/SDVDD are powered up with IVDD at 0 V, then the sense circuits in the I/O pads will 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 will be 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.
3.4.2
Power Down Sequence
If IVDD/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 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 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.
2.
Drop IVDD/PLLVDD to 0 V.
Drop EVDD/SDVDD supplies.

Signal Multiplexing
The following table lists all the MCF5227x pins grouped by function. The direction column is the direction for the primary
function of the pin only. Refer to Section 4, “Pin Assignments and Reset States,” for package diagrams. For a more detailed
discussion of the MCF5227x signals, consult the MCF52277 Reference Manual (MCF52277RM).
NOTE
In this table and throughout this document a single signal within a group is designated
without square brackets (i.e., FB_A23), while designations for multiple signals within a
group use brackets (i.e., FB_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. Most pins that
are muxed with GPIO will default to their GPIO functionality. See Table 5 for a list of the
exceptions.

Pull-ups are generally only enabled on pins with their primary function, except as noted.
Refers to pin’s primary function.
Enabled only in oscillator bypass mode (internal crystal oscillator is disabled).
GPIO functionality is determined by the edge port module. The GPIO module is only responsible for assigning the alternate functions.
Pull-up when DREQ controls the pin.
The 176 LQFP device only supports a 12-bit LCD data bus.
DSPI or SBF signal functionality is controlled by RESET. When asserted, these pins are configured for serial boot; when negated, the
pins are configured for DSPI.
Pull-up when the serial boot facility (SBF) controls the pin.
If JTAG_EN is asserted, these pins default to alternate 1 (JTAG) functionality. The GPIO module is not responsible for assigning these
pins.

Electrical Characteristics
This document contains electrical specification tables and reference timing diagrams for the MCF5227x microprocessor. This
section contains detailed information on DC/AC electrical characteristics and AC timing specifications.
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.

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 (e.g., either 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, 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. Insure external EVDD 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 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

The average chip-junction temperature (TJ) in °C can be obtained from:

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.

External Interface Timing Specifications
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 66MHz. 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.

Electrical Characteristics
All processor bus timings are synchronous; that is, input setup/hold and output delay are given in respect to the rising edge of
a reference clock, FB_CLK. The FB_CLK frequency may be the same as the internal system bus frequency or an integer divider
of that frequency.
The following timing numbers indicate when data will be latched or driven onto the external bus, relative to the Flexbus output
clock, FB_CLK. All other timing relationships can be derived from these values.

The FlexBus supports programming an extension of the address hold. Please consult the device 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.

The SDRAM controller supports accesses to main SDRAM memory from any internal master. It supports either standard
SDRAM or double data rate (DDR) SDRAM, but it does not support both at the same time.
5.7.2.1
SDR SDRAM AC Timing Specifications
The following timing numbers indicate when data will be 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 still be 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

Please see the PLL chapter of the device 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.
SD_SDR_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_SDR_DQS will only pulse during a read cycle and one pulse will occur for each
data beat.
SD_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. SD_DQS will only pulse during a read cycle and one pulse will occur for each data
beat.
The SD_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.
Since a read cycle in SDR mode still uses the DQS circuit within the device, it is critical that the data valid window be centered
1/4 clk after the rising edge of DQS. Ensuring that this happens will result in successful SDR reads. The input setup spec is
provided as guidance.

The frequency of operation is either 2x or 4x the FB_CLK frequency of operation. FlexBus and SDRAM clock operate at the
same frequency as the internal bus clock.
SD_CLK is one SDRAM clock in ns.
Pulse-width high plus pulse-width low cannot exceed minimum or maximum clock period.
Command output valid should be one-half 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 device’s output setup should be larger
than the input setup of the DDR memories. If it is not larger, then the input setup on the memory will be 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_DATA[7:0] is relative MEM_DQS[0].
The first data beat will be valid before the first rising edge of DQS and after the DQS write preamble. The remaining data beats
will be 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_DATA[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.

SSI Timing Specifications
This section provides the AC timings for the SSI in master (clocks driven) and slave modes (clocks input). All timings are given
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.

SSI_BCLK can be derived from SSI_CLKIN or a divided version of SYSCLK. If the SYSCLK is used, the minimum
divider is 6. If the SSI_CLKIN input is used, the programmable dividers must be set to ensure that SSI_BCLK does
not exceed 4 x fSYS.

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 29. 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 29
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.
