Hardware Design Considerations
3.1
Analog Power Filtering
To further enhance noise isolation, an external filter is strongly recommended for the analog VDD pins (VDD_A_PLL,
VDD_RTC). The filter shown in Figure 2 should be connected between the board IVDD and the analog pins. The resistor and
capacitors should be placed as close to the dedicated analog VDD pin as possible. The 10-Ω resistor in the given filter is required.
Do not implement the filter circuit using only capacitors. The analog power pins draw very little current. Concerns regarding
voltage loss across the 10-ohm resistor are not valid.

Supply Voltage Sequencing
Figure 4 shows situations in sequencing the I/O VDD (EVDD), SDRAM VDD (SDVDD), PLL VDD (PVDD), and internal
logic/core VDD (IVDD).

Time
Notes:
1
Input voltage must not be greater than the supply voltage (EVDD, SDVDD, IVDD, or PVDD) by more than 0.5V
at any time, including during power-up.
2
Use 50 V/millisecond or slower rise time for all supplies.
Figure 4. 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
1.8V) and EVDD are specified relative to IVDD.

Pin Assignments and Reset States
3.3.1
Power-Up Sequence
If EVDD/SDVDD are powered up with the 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 power up. The rise times on the power supplies should be slower than 50 V/millisecond to avoid turning on the internal
ESD protection clamp diodes.
3.3.2
Power-Down Sequence
If IVDD/PVDD 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 PVDD power down before EVDD or SDVDD must power down. There are no
requirements for the fall times of the power supplies.

Pin Assignments and Reset States
4.1
Signal Multiplexing
The following table lists all the MCF5445x pins grouped by function. The Dir 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 MCF5445x signals, consult the MCF54455 Reference Manual (MCF54455RM).
NOTE
In this table and throughout this document, a single signal within a group is designated
without square brackets (i.e., FB_AD23), while designations for multiple signals within a
group use brackets (i.e., FB_AD[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 default to their GPIO functionality. See Table 3 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).
Serial boot must select 0-bit boot port size to enable the GPIO mode on these pins.
When the PCI is enabled, all PCI bus pins come up configured as such. This includes the PCI_GNT and PCI_REQ lines, which have
GPIO. The IRQ1/PCI_INTA signal is a special case. It comes up as PCI_INTA when booting as a PCI agent and as GPIO when booting
as a PCI host.
For the 360 TEPBGA, booting with PCI disabled results in all dedicated PCI pins being safe-stated. The PCI_GNT and PCI_REQ lines
and IRQ1/PCI_INTA come up as GPIO.
GPIO functionality is determined by the edge port module. The pin multiplexing and control module is only responsible for assigning
the alternate functions.
Depends on programmed polarity of the USB_VBUS_OC signal.
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 pin multiplexing and control module is not
responsible for assigning these pins.

Electrical Characteristics
This document contains electrical specification tables and reference timing diagrams for the MCF54455 microprocessor. This
section contains detailed information on DC/AC electrical characteristics and AC timing specifications.
The electrical specifications are preliminary and 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 Table 8. Absolute maximum ratings are stress ratings only, and functional
operation at the maximum 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., 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 the external EVDD load shunts current greater
than maximum injection current. This is the greatest risk when the MPU is not consuming power (ex; no clock). The 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.

IVDD and PVDD should be at the same voltage. PVDD should have a filtered input. Please see the PLL section of this
specification for an example circuit. There are three PVDD inputs, one for each PLL. A filter circuit should used on each
PVDD input.
Worst-case tristate leakage current with only one I/O pin high. Since all I/Os share power when high, the leakage current
is distributed among them. With all I/Os high, this spec reduces to ±2 μA min/max.
Refer to the MCF54455 Reference Manual signals description chapter for pins having weak internal pull-up devices.
This parameter is characterized before qualification rather than 100% tested.
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. Ensure the external VDD load shunts current greater
than the maximum injection current. This is 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,
the system clock is not present during the power-up sequence until the PLL has attained lock.
ClockTiming Specifications
The clock module configures the device for one of several clocking methods. Clocking modes include internal phase-locked
loop (PLL) clocking with an external clock reference or an external crystal reference supported by an internal crystal amplifier.
The PLL can also be disabled, and an external oscillator can directly clock the device.
The specifications in Table 9 are for the CLKIN input pin (EXTAL input driven by an external clock reference). The duty cycle
specification is based on an acceptable tolerance for the PLL, which yields 50% duty-cycle internal clocks to all on-chip
peripherals. The MCF5445x devices use the input clock signal as its synchronous bus clock for PCI. A poor duty cycle on the
input clock, may affect the overall timing margin to external devices. If negative edge logic is used to interface to PCI, providing
a 50% duty-cycle input clock aids in simplifying overall system design.

The minimum system frequency is the minimum input clock divided by the maximum low-power divider (16 MHz ÷ 32,768).
When the PLL is enabled, the minimum system frequency (fsys) is 150 MHz.
This parameter is guaranteed by characterization before qualification rather than 100% tested. Applies to external clock
reference only.
Proper PC board layout procedures must be followed to achieve specifications.
This parameter is guaranteed by design rather than 100% tested.
This specification is the PLL lock time only and does not include oscillator start-up time.
CS_PCB is the measured PCB stray capacitance on EXTAL and XTAL.
Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum fsys.
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.

RESET and Configuration Override data lines are synchronized internally. Setup and hold times must be met only if
recognition on a particular clock is required.
2 During low power STOP, the synchronizers for the RESET input are bypassed and RESET is asserted asynchronously
to the system. Thus, RESET must be held a minimum of 100 ns.

FlexBus Timing Specifications
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.
All processor bus timings are synchronous; 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 is 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.

2 Specification is valid for all FB_AD[31:0] and FB_TA.
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 PCI
controller. At the end of the read and write bus cycles the address signals are
indeterminate.

The SDRAM interface operates at the same frequency as the internal system bus.
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 (tSDCK) plus some minor adjustments for process, temperature, and
voltage variations.
This specification relates to the required input setup time of DDR memories. The microprocessor’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 is in violation.
SD_D[31:24] is relative to SD_DQS[3]; SD_D[23:16] is relative to SD_DQS[2]
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 DDR memories.
SD_D[31:24] is relative to SD_DQS[3]; SD_D[23:16] is relative to SD_DQS[2]
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.

ULPI Timing Specifications
The ULPI interface is fully compliant with the industry standard UTMI+ Low Pin Interface. Control and data timing
requirements for the ULPI pins are given in Table 15. These timings apply to synchronous mode only. All timings are measured
with respect to the clock as seen at the USB_CLKIN pin on the MCF5445x. The ULPI PHY is the source of the 60MHz clock.
NOTE
The USB controller requires a 60-MHz clock, even if using the on-chip FS/LS transceiver
instead of the ULPI interface. In this case, the 60-MHz clock can be generated by the PLL
or input on the USB_CLKIN pin.

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.

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 19. 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 19 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.

Sept 17, 2007 Initial public release.
1
Feb 15, 2008 Corrected VSS pin locations in MCF5445x signal information and muxing table for the 360 TEPBGA
package: changed “...M9, M16, M17...” to “...M9–M14, M16...”
Updated FlexBus read and write timing diagrams and added two notes before them.
Change FB_A[23:0] to FB_A[31:0] in FlexBus read and write timing diagrams.
Added power consumption section.
2
May 1, 2008 In Family Configurations table, added PCI as feature on 256-pin devices. On these devices the
PCI_AD bus is limited to 24-bits.
In Absolute Maximum Ratings table, changed RTCVDD specification from “-0.3 to +4.0” to “-0.5 to
+2.0”.
In DC Electrical Specifications table:
• Changed RTCVDD specification from 3.0–3.6 to 1.35–1.65.
• Changed High Impedance (Off-State) Leakage Current (IOZ) specification from ±1 to ±10μA, and
added footnote to this spec: “Worst-case tristate leakage current with only one I/O pin high. Since
all I/Os share power when high, the leakage current is distributed among them. With all I/Os high,
this spec reduces to ±2 μA min/max.“
