2 MC56F827xx signal and pin descriptions
After reset, each pin is configured for its primary function (listed first). Any alternative
functionality, shown in parentheses, must be programmed through the GPIO module
peripheral enable registers (GPIOx_PER) and the SIM module GPIO peripheral select
(GPSx) registers. All GPIO ports can be individually programmed as an input or output
(using bit manipulation).
• PWMA_FAULT0, PWMA_FAULT1, and similar signals are inputs used to disable
selected PWMA outputs, in cases where the fault conditions originate off-chip.
For the MC56F827xx products, which use 64-pin LQFP, 48-pin LQFP and 32-pin
packages:

7.3 ESD handling ratings
Although damage from electrostatic discharge (ESD) is much less common on these
devices than on early CMOS circuits, use normal handling precautions to avoid exposure
to static discharge. Qualification tests are performed to ensure that these devices can
withstand exposure to reasonable levels of static without suffering any permanent
damage.
All ESD testing is in conformity with AEC-Q100 Stress Test Qualification. During the
device qualification ESD stresses were performed for the human body model (HBM), the
machine model (MM), and the charge device model (CDM).
All latch-up testing is in conformity with AEC-Q100 Stress Test Qualification.
A device is defined as a failure if after exposure to ESD pulses, the device no longer
meets the device specification. Complete DC parametric and functional testing is
performed as per the applicable device specification at room temperature followed by hot
temperature, unless specified otherwise in the device specification.

3. All 5 volt tolerant digital I/O pins are internally clamped to VSS through a ESD protection diode. There is no diode
connection to VDD. If VIN greater than VDIO_MIN (= VSS–0.3 V) is observed, then there is no need to provide current
limiting resistors at the pads. If this limit cannot be observed, then a current limiting resistor is required.
4. I/O is configured as push-pull mode.
8 General
8.1 General characteristics
The device is fabricated in high-density, low-power CMOS with 5 V–tolerant TTLcompatible digital inputs, except for the RESET pin which is 3.3V only. The term “5 V–
tolerant” refers to the capability of an I/O pin, built on a 3.3 V–compatible process
technology, to withstand a voltage up to 5.5 V without damaging the device.
5 V–tolerant I/O is desirable because many systems have a mixture of devices designed
for 3.3 V and 5 V power supplies. In such systems, a bus may carry both 3.3 V– and 5 V–
compatible I/O voltage levels (a standard 3.3 V I/O is designed to receive a maximum
voltage of 3.3 V ± 10% during normal operation without causing damage). This 5 V–
tolerant capability therefore offers the power savings of 3.3 V I/O levels combined with
the ability to receive 5 V levels without damage.
Absolute maximum ratings in Table 5 are stress ratings only, and functional operation at
the maximum is not guaranteed. Stress beyond these ratings may affect device reliability
or cause permanent damage to the device.
Unless otherwise stated, all specifications within this chapter apply over the temperature
range of -40°C to 105°C ambient temperature over the following supply ranges:
VSS=VSSA=0V, VDD=VDDA=3.0V to 3.6V, CL≤50 pF, fOP=50MHz.
CAUTION
This device contains protective circuitry to guard against
damage due to high static voltage or electrical fields. However,
normal precautions are advised to avoid application of any
voltages higher than maximum-rated voltages to this highimpedance circuit. Reliability of operation is enhanced if
unused inputs are tied to an appropriate voltage level.

8.5.2 Thermal attributes
This section provides information about operating temperature range, power dissipation,
and package thermal resistance. Power dissipation on I/O pins is usually small compared
to the power dissipation in on-chip logic and voltage regulator circuits, and it is userdetermined rather than being controlled by the MCU design. To account for PI/O in power
calculations, determine the difference between actual pin voltage and VSS or VDD and
multiply by the pin current for each I/O pin. Except in cases of unusually high pin current
(heavy loads), the difference between pin voltage and VSS or VDD is very small.
See Thermal design considerations for more detail on thermal design considerations.

9.2.1 Voltage regulator specifications
The voltage regulator supplies approximately 1.2 V to the MC56F82xxx’s core logic. For
proper operations, the voltage regulator requires an external 2.2 µF capacitor on each
VCAP pin. Ceramic and tantalum capacitors tend to provide better performance
tolerances. The output voltage can be measured directly on the VCAP pin. The
specifications for this regulator are shown in Table 17.

10 Design Considerations
10.1 Thermal design considerations
An estimate of the chip junction temperature (TJ) can be obtained from the equation:
TJ = TA + (RΘJA x PD)
MC56F827xx Data Sheet, Rev. 2.1, 11/2013.
62
Freescale Semiconductor, Inc.
Design Considerations
Where,
TA = Ambient temperature for the package (°C)
RΘJA = Junction-to-ambient thermal resistance (°C/W)
PD = Power dissipation in the package (W)
The junction-to-ambient thermal resistance is an industry-standard value that provides a
quick and easy estimation of thermal performance. Unfortunately, there are two values in
common usage: the value determined on a single-layer board and the value obtained on a
board with two planes. For packages such as the PBGA, these values can be different by
a factor of two. Which TJ value is closer to the application depends on the power
dissipated by other components on the board.
• The TJ value obtained on a single layer board is appropriate for a tightly packed
printed circuit board.
• The TJ value obtained on a board with the internal planes is usually appropriate if the
board has low-power dissipation and if the components are well separated.
When a heat sink is used, the thermal resistance is expressed as the sum of a junction-tocase thermal resistance and a case-to-ambient thermal resistance:
RΘJA = RΘJC + RΘCA
Where,
RΘJA = Package junction-to-ambient thermal resistance (°C/W)
RΘJC = Package junction-to-case thermal resistance (°C/W)
RΘCA = Package case-to-ambient thermal resistance (°C/W)
RΘJC is device related and cannot be adjusted. You control the thermal environment to
change the case to ambient thermal resistance, RΘCA. For instance, you can change the
size of the heat sink, the air flow around the device, the interface material, the mounting
arrangement on printed circuit board, or change the thermal dissipation on the printed
circuit board surrounding the device.
To determine the junction temperature of the device in the application when heat
sinks are not used, the thermal characterization parameter (YJT) can be used to
determine the junction temperature with a measurement of the temperature at the top
center of the package case using the following equation:
TJ = TT + (ΨJT x PD)
Where,
TT = Thermocouple temperature on top of package (°C/W)
MC56F827xx Data Sheet, Rev. 2.1, 11/2013.
Freescale Semiconductor, Inc.
63
Design Considerations
ΨJT = hermal characterization parameter (°C/W)
PD = Power dissipation in package (W)
The thermal characterization parameter is measured per JESD51–2 specification using a
40-gauge type T thermocouple epoxied to the top center of the package case. The
thermocouple should be positioned so that the thermocouple junction rests on the
package. A small amount of epoxy is placed over the thermocouple junction and over
about 1 mm of wire extending from the junction. The thermocouple wire is placed flat
against the package case to avoid measurement errors caused by cooling effects of the
thermocouple wire.
To determine the junction temperature of the device in the application when heat
sinks are used, the junction temperature is determined from a thermocouple inserted at
the interface between the case of the package and the interface material. A clearance slot
or hole is normally required in the heat sink. Minimizing the size of the clearance is
important to minimize the change in thermal performance caused by removing part of the
thermal interface to the heat sink. Because of the experimental difficulties with this
technique, many engineers measure the heat sink temperature and then back-calculate the
case temperature using a separate measurement of the thermal resistance of the interface.
From this case temperature, the junction temperature is determined from the junction-tocase thermal resistance.
10.2 Electrical design considerations
CAUTION
This device contains protective circuitry to guard against
damage due to high static voltage or electrical fields. However,
take normal precautions 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 voltage level.
Use the following list of considerations to assure correct operation of the device:
• Provide a low-impedance path from the board power supply to each VDD pin on the
device and from the board ground to each VSS (GND) pin.
• The minimum bypass requirement is to place 0.01–0.1 µF capacitors positioned as
near as possible to the package supply pins. The recommended bypass configuration
is to place one bypass capacitor on each of the VDD/VSS pairs, including VDDA/VSSA.
Ceramic and tantalum capacitors tend to provide better tolerances.
• Ensure that capacitor leads and associated printed circuit traces that connect to the
chip VDD and VSS (GND) pins are as short as possible.

Obtaining package dimensions
• Bypass the VDD and VSS with approximately 100 µF, plus the number of 0.1 µF
ceramic capacitors.
• PCB trace lengths should be minimal for high-frequency signals.
• Consider all device loads as well as parasitic capacitance due to PCB traces when
calculating capacitance. This is especially critical in systems with higher capacitive
loads that could create higher transient currents in the VDD and VSS circuits.
• Take special care to minimize noise levels on the VREF, VDDA, and VSSA pins.
• Using separate power planes for VDD and VDDA and separate ground planes for VSS
and VSSA are recommended. Connect the separate analog and digital power and
ground planes as near as possible to power supply outputs. If an analog circuit and
digital circuit are powered by the same power supply, then connect a small inductor
or ferrite bead in serial with VDDA. Traces of VSS and VSSA should be shorted
together.
• Physically separate analog components from noisy digital components by ground
planes. Do not place an analog trace in parallel with digital traces. Place an analog
ground trace around an analog signal trace to isolate it from digital traces.
• Because the flash memory is programmed through the JTAG/EOnCE port, SPI, SCI,
or I2C, the designer should provide an interface to this port if in-circuit flash
programming is desired.
• If desired, connect an external RC circuit to the RESET pin. The resistor value
should be in the range of 4.7 kΩ–10 kΩ; the capacitor value should be in the range of
0.22 µF–4.7 µF.
• Configuring the RESET pin to GPIO output in normal operation in a high-noise
environment may help to improve the performance of noise transient immunity.
• Add a 2.2 kΩ external pullup on the TMS pin of the JTAG port to keep EOnCE in a
restate during normal operation if JTAG converter is not present.
• During reset and after reset but before I/O initialization, all I/O pins are at tri-state.
• To eliminate PCB trace impedance effect, each ADC input should have a no less than
33 pF 10Ω RC filter.
