Features:
• 8-Bit RS08 Central Processor Unit (CPU)
– Up to 20 MHz CPU at 2.7 V to 5.5 V across temperature
range of –40°C to 85°C
– Subset of HC08 instruction set with added BGND
instructions
• On-Chip Memory
– 4 KB flash memory read/program/erase over full
operating voltage and temperature
– 256-byte random-access memory (RAM)
– Security circuitry to prevent unauthorized access to flash
memory contents
• Power-Saving Modes
– Wait and stop
• 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 20 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 bus frequencies up to 10 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 detection with reset or interrupt
– Selectable trip points
– Illegal opcode detection with reset
– Illegal address detection with reset
– Flash memory block protection
• Development Support
– Single-wire background debug interface
– Breakpoint capability to allow single breakpoint setting
during in-circuit debugging
