MC9S08QE128 Series Features
8-Bit HCS08 Central Processor Unit (CPU)
Up to 50.33-MHz HCS08 CPU from 3.6 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

On-Chip Memory
Flash read/program/erase over full operating voltage and
temperature
Random-access memory (RAM)
Security circuitry to preventunauthorized access to RAM
and flash contents
Power-Saving Modes
Two very low power stop modes, one of which allows
limited use of peripherals
Reduced power wait mode
Peripheral clock enable register can disable clocks to
unused modules, thereby reducingcurrents;allows clocks
to remain enabled to specific peripherals in stop3 mode
Very low power external oscillator that can be used in
stop3 mode to provide accurate clock source to active
peripherals
Very low power real time counter for use in run, wait, and
stop modes with internal and external clock sources
•6μs typical wake up time from stop3 mode

(TPM1 and TPM2); Selectable input capture, output
compare, or buffered edge- or center-aligned PWM on
each channel
