MC9S08QE32 Series
Covers: MC9S08QE32 and
MC9S08QE16
Features
• 8-Bit HCS08 Central Processor Unit (CPU)
– Up to 50.33 MHz HCS08 CPU at 3.6 V to 2.4 V, 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
– HC08 instruction set with added BGND instruction
– Support for up to 32 interrupt/reset sources
• 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 very low power stop modes
– Reduced power wait mode
– Peripheral clock enable register can disable clocks to unused
modules, thereby reducing currents; allows clocks to remain enabled
to specific peripherals in stop3 mode.
– Very low power external oscillator that can be used in run, wait, and
stop modes to provide accurate clock source to real time counter.
– 6
s
typical wakeup time from stop3 mode
• Clock Source Options
– Oscillator (XOSCVLP) — 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) — Internal clock source module
containing a frequency-locked-loop (FLL) controlled by internal or
external reference; precision trimming of internal reference allows
0.2% resolution and 2% deviation over temperature and voltage;
supports CPU frequencies from
4 kHz 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 warning with interrupt.
– Low-voltage detection with reset or interrupt
– Selectable trip points.
– Illegal opcode detection with reset
– Illegal address detection with reset
– Flash block protection
• Development Support
– Single-wire background debug interface
– Breakpoint capability to allow single breakpoint setting during
in-circuit debugging (plus three breakpoints in on-chip debug
module)
