• 32-Bit Version 1 ColdFire® Central Processor Unit (CPU)
– Up to 50.33-MHz ColdFire V1 CPU above 2.4V,
40-MHz CPU above 2.1V, and 20-MHz CPU above
1.8V, across temperature range
– Provides 0.94 Dhrystone 2.1 MIPS per MHz
performance when running from internal RAM
(0.76 DMIPS/MHz from flash)
– Implements Instruction Set Revision C (ISA_C)
– Support for up to 30 peripheral interrupt requests and
seven software interrupts
• On-Chip Memory
– Flash read/program/erase over full operating voltage
and temperature
– Random-access memory (RAM)
– Security circuitry to prevent unauthorized access to
RAM and flash contents
• Power-Saving Modes
– Two low power stop modes; reduced power wait mode
– Peripheral clock enable register can disable clocks to
unused modules, reducing currents; allows clocks to
remain enabled to specific peripherals in stop3 mode
– Very low power external oscillator can be used in stop3
mode to provide accurate clock to active peripherals
– Very low power real time counter for use in run, wait,
and stop modes with internal and external clock sources
– 6 μs typical wake up time from stop modes
• Clock Source Options
– Oscillator (XOSC) — Loop-control Pierce oscillator;
Crystal or ceramic resonator range of 31.25 kHz to
38.4 kHz or 1 MHz to 16 MHz
– Internal Clock Source (ICS) — FLL controlled by
internal or external reference; precision trimming of
internal reference allows 0.2% resolution and 2%
deviation; supports CPU freq. from 2 to 50.33 MHz
• System Protection
– Watchdog computer operating properly (COP) reset
with option to run from dedicated 1-kHz internal clock
source or bus clock
– Low-voltage detection with reset or interrupt; selectable
trip points
– Illegal opcode and illegal address detection with
programmable reset or exception response
– Flash block protection

time; automatic compare function; 1.7 mV/°C temperature
sensor; internal bandgap reference channel; operation in
stop3; fully functional from 3.6V to 1.8V
• ACMPx — Two analog comparators with selectable
interrupt on rising, falling, or either edge of comparator
output; compare option to fixed internal bandgap reference
voltage; outputs can be optionally routed to TPM module;
operation in stop3
• SCIx — Two SCIs with full duplex non-return to zero
(NRZ); LIN master extended break generation; LIN slave
extended break detection; wake up on active edge
• SPIx— Two serial peripheral interfaces with Full-duplex or
single-wire bidirectional; Double-buffered transmit and
receive; MSB-first or LSB-first shifting
• IICx — Two IICs with; Up to 100 kbps with maximum bus
loading; Multi-master operation; Programmable slave
address; Interrupt driven byte-by-byte data transfer;
supports broadcast mode and 10 bit addressing
• TPMx — One 6-channel and two 3-channel; Selectable
input capture, output compare, or buffered edge- or
center-aligned PWMs on each channel
• RTC — 8-bit modulus counter with binary or decimal
based prescaler; External clock source for precise time
base, time-of-day, calendar or task scheduling functions;
Free running on-chip low power oscillator (1 kHz) for
cyclic wake-up without external components
• Input/Output
– 70 GPIOs and 1 input-only and 1 output-only pin
– 16 KBI interrupts with selectable polarity
– Hysteresis and configurable pull-up device on all input
pins; Configurable slew rate and drive strength on all
output pins.
– SET/CLR registers on 16 pins (PTC and PTE)
– 16 bits of Rapid GPIO connected to the CPU’s
high-speed local bus with set, clear, and toggle
functionality

Introduction
This section contains electrical and timing specifications for the MCF51QE128 series of microcontrollers available at the time
of publication.
3.2
Parameter Classification
The electrical parameters shown in this supplement are guaranteed by various methods. To give the customer a better
understanding the following classification is used and the parameters are tagged accordingly in the tables where appropriate:
Table 3. Parameter Classifications
P
Those parameters are guaranteed during production testing on each individual device.
C
Those parameters are achieved by the design characterization by measuring a statistically relevant sample
size across process variations.
T
Those parameters are achieved by design characterization on a small sample size from typical devices
under typical conditions unless otherwise noted. All values shown in the typical column are within this
category.
D
Those parameters are derived mainly from simulations.
NOTE
The classification is shown in the column labeled “C” in the parameter tables where
appropriate.
3.3
Absolute Maximum Ratings
Absolute maximum ratings are stress ratings only, and functional operation at the maxima is not guaranteed. Stress beyond the
limits specified in Table 4 may affect device reliability or cause permanent damage to the device. For functional operating
conditions, refer to the remaining tables in this section.
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 (for
instance, either VSS or VDD) or the programmable pull-up resistor associated with the pin is enabled.

Input must be current limited to the value specified. To determine the value of the required
current-limiting resistor, calculate resistance values for positive (VDD) and negative (VSS) clamp
voltages, then use the larger of the two resistance values.
2
All functional non-supply pins are internally clamped to VSS and VDD.
3
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 external VDD load will shunt current greater than maximum injection
current. This will be the greatest risk when the MCU is not consuming power. Examples are: if
no system clock is present, or if the clock rate is very low (which would reduce overall power
consumption).
3.4
Thermal Characteristics
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 user-determined rather than being controlled by the MCU design. To take PI/O into account 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 will be very small.

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

Eqn. 1
where:
TA = Ambient temperature, °C
θJA = Package thermal resistance, junction-to-ambient, °C/W
PD = Pint + PI/O

Typical values are measured at 25°C. Characterized, not tested
As the supply voltage rises, the LVD circuit will hold the MCU in reset until the supply has risen above VLVDL.
All functional non-supply pins are internally clamped to VSS and 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 external VDD load will shunt current greater than maximum injection
current. This will be 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).
Maximum is highest voltage that POR is guaranteed.

The resulting bus clock frequency should not exceed the maximum specified bus clock frequency of the device.

This specification applies to any time the FLL reference source or reference divider is changed, trim value changed or changing
from FLL disabled (FBELP, FBILP) to FLL enabled (FEI, FEE, FBE, FBI). If a crystal/resonator is being used as the reference,
this specification assumes it is already running.
4 Jitter is the average deviation from the programmed frequency measured over the specified interval at maximum f
Bus.
Measurements are made with the device powered by filtered supplies and clocked by a stable external clock signal. Noise
injected into the FLL circuitry via VDD and VSS and variation in crystal oscillator frequency increase the CJitter percentage for a
given interval.

Typical values are based on characterization data at VDD = 3.0V, 25°C unless otherwise stated.
This is the shortest pulse that is guaranteed to be recognized as a reset or interrupt pin request. Shorter pulses are not
guaranteed to override reset requests from internal sources.
3 To enter BDM mode following a POR, BKGD/MS should be held low during the power-up and for a hold time of t
MSH after VDD
rises above VLVD.
4 This is the minimum assertion time in which the interrupt may be recognized. The correct protocol is to assert the interrupt
request until it is explicitly negated by the interrupt service routine.
5 Timing is shown with respect to 20% V
DD and 80% VDD levels. Temperature range –40°C to 85°C.

The frequency of this clock is controlled by a software setting.
These values are hardware state machine controlled. User code does not need to count cycles. This information supplied
for calculating approximate time to program and erase.
3
The program and erase currents are additional to the standard run IDD. These values are measured at room temperatures
with VDD = 3.0 V, bus frequency = 4.0 MHz.
4 Typical endurance for flash was evaluated for this product family on the HC9S12Dx64. For additional information on
how Freescale defines typical endurance, please refer to Engineering Bulletin EB619, Typical Endurance for Nonvolatile
Memory.
5 Typical data retention values are based on intrinsic capability of the technology measured at high temperature and
de-rated to 25°C using the Arrhenius equation. For additional information on how Freescale defines typical data retention,
please refer to Engineering Bulletin EB618, Typical Data Retention for Nonvolatile Memory.
