8-Bit HCS08 Central Processor Unit (CPU)
• Up to 40 MHz HCS08 CPU (central processor unit); up to 20 MHz bus frequency
• HC08 instruction set with added BGND instruction

On-Chip Memory
• 4 KB of FLASH with read/program/erase over full operating voltage and temperature
• 256 bytes of Random-access memory (RAM)

Power-Saving Modes
• Two very low power stop modes
• Reduced power wait mode

Clock Source Options
• Oscillator (XOSC) — Loop-control Pierce oscillator; Crystal or ceramic resonator range of 32 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 2.0 % deviation over temperature and voltage; supports bus frequencies from 2 MHz to 20 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 block protect
• Reset on loss of clock

Development Support
• Single-wire background debug interface
• Breakpoint capability to allow single breakpoint setting during in-circuit debugging
