• 8-Bit RS08 Central Processor Unit (CPU)
– Up to 20 MHz CPU at 1.8 V to 5.5 V across temperature
range of –40 °C to 85 °C
– Subset of HC08 instruction set with added BGND
instruction
– Single Global interrupt vector
• On-Chip Memory
– Up to 12 KB flash read/program/erase over full
operating voltage and temperature,
12 KB/8 KB/4 KB/2 KB flash are optional
– Up to 254-byte random-access memory (RAM),
254-byte/126-byte RAM are optional
– Security circuitry to prevent unauthorized access to flash
contents
• Power-Saving Modes
– Wait mode — CPU shuts down; system clocks continue
to run; full voltage regulation
– Stop mode — CPU shuts down; system clocks are
stopped; voltage regulator in standby
– Wakeup from power-saving modes using RTI, KBI,
ADC, ACMP, SCI and LVD
• Clock Source Options
– Oscillator (XOSC) — Loop-control Pierce oscillator;
crystal or ceramic resonator range of 31.25 kHz to
39.0625 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;
supporting bus frequencies up to 10 MHz
• System Protection
– Watchdog computer operating properly (COP) reset
with option to run from dedicated 1 kHz internal low
power oscillator
– Low-voltage detection with reset or interrupt
– Illegal opcode detection with reset
– Illegal address detection with reset
– Flash-block protection
