Overview
Achieving raw performance is no longer the
number one issue—it’s now “performance within
an energy budget.” Freescale understands this
challenge and offers a wide portfolio of S08
devices that help you reach target performance
levels while minimizing low power in your
design. The QE family demonstrates extreme
energy efficiency for ultra-long operating life
in battery-powered applications.
Further expanding the QE family portfolio, the
QE32 provides great flexibility for customers to
balance performance and power consumption.
The QE32 offers low-power features such as
two ultra-low-power stop modes, low-power run
and wait modes, 6 usec wake-up time, ultralow-power external oscillator and clock gating
registers to disable clocks to unused peripherals.
The QE32 offers up to 32 KB of flash memory,
a 10-channel, 12-bit resolution analog-to-digital
converter (ADC), abundant peripherals such as
three timers/PWM, two SCI, SPI, I2C and two
analog comparators. QE32 can operate at 1.8V
voltage supply and run up to 50.33 MHz
core frequency.

40 MHz CPU at 2.4 V to 2.1 V and 20 MHz CPU
at 2.1 V to 1.8 V across temperature range of
-40 °C to +85 °C
• Offers high performance, even at low voltage levels
for battery-operated applications
• Provides bus speed operation from 10 MHz to
25.165 MHz under voltage from 1.8V to 3.6V
• HCS08 instruction set with added BGND instruction
• Easy to learn and use architecture
• Backward object code compatibility with 68HC08 and
68HC05 for reuse of existing libraries can still be used
• Allows for efficient, compact module coding in
assembly or C compiler
• BGND allows user to enter background debug
mode that takes advantage of on-chip
in-circuit emulator (ICE)
On-Chip Memory

operating voltage and temperature
• Allows user to take full advantage of
in-application, reprogrammability benefits in
virtually any environment
• Up to range of 1.8V to 3.6V RAM
• Security circuitry prevents unauthorized access
to RAM and flash contents to reduce system
power consumption

Package Options
Peripherals
• Analog-to-digital converter (ADC)—10-channel,
12-bit resolution; 2.5 µs conversion time; automatic
compare function; internal temperature sensor;
internal bandgap reference channel; operation
in stop mode
• Having 10 channels allows up to 10 analog
devices to be sampled at extremely high speeds
• Accuracy and full functionality guaranteed across
1.8V to 3.6V operating voltage of the MCU
• Timer—One 6-channel (TPM3) and two 3-channel
(TPM1 and TPM2); selectable input capture, output
compare, or buffered edge- or center-aligned PWM
on each channel
• Three TPMs allow for three different time bases,
with a total of twelve timer channels
• 2 x Serial Communications Interface (SCI)—Two SCI
interface modules with optional 13-bit break; offer
LIN master/slave extended break generation
• Have two SCI allows two separate
dedicated devices
• Allows full-duplex, asynchronous, NRZ serial
communication between MCU and remote devices
• Edge interrupt can wake up MCU from
low-power mode
• Two analog comparators with option to compare
to an internal reference—output can be optionally
routed to timer/pulse width modulator (PWM) as
input capture trigger
• Requires only single pin for input signal, freeing additional pins for other use
• Allows other components in system to see result
of comparator with minimal delay
• Can be used for single slope ADC and RC time
constant measurements
• Serial Peripheral Interface (SPI)—one module
with full-duplex or single-wire bidirectional;
double-buffered transmit and receive; master
or slave mode; MSB-first or LSB-first shifting
• Allows high-speed (up to 5 Mbps) communications
to other MCUs or peripherals such as MC1319x
RF transceivers
• I2C 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
• I2C port enables increased system memory by
using an additional I2C EEPROM. This also creates
an opportunity to add an additional I2C device.
