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, ultra-
low-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.
To test your application with the QE family, take

Features
Power-Saving Features
• Two ultra-low-power stop modes, one of which
allows limited use of peripherals
• Low-power run and wait modes
• 6 µs typical wake up time from stop mode
• Internal clock Source (ICS)—module containing a
frequency locked-loop (FLL) controlled by internal
or external reference
• Oscillator (OSC)—loop-control Pierce oscillator;
crystal or ceramic resonator range of 31.25 kHz to
38.4 kHz or 1 MHz to 16 MHz
• Clock gating disables clocks to unused peripherals
8-bit HCS08 Central Processing Unit (CPU)
• Up to 50.33 MHz HCS08 CPU at 3.6V to 2.4V,
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
• HCS08 instruction set with added BGND instruction
On-Chip Memory
• Up to 32 KB flash read/program/erase over full
operating voltage and temperature
• Up to range of 1.8V to 3.6V RAM
Benefits
• Allows continued application sampling in a reduced
power state which extends battery life
• Allows use of all chip peripherals in a low-power state
• Enables faster execution out of stop modes
• Provides choice of frequencies on-the-fly.
Reducing frequency saves current.
• Includes ultra-low-power OSC for accurate
timebase in low-power modes
• Provides flexibility to turn off individual modules
• Reduces power consumption
• 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
• 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)
• Allows user to take full advantage of
in-application, reprogrammability benefits in
virtually any environment
• Security circuitry prevents unauthorized access
to RAM and flash contents to reduce system
power consumption
