MC9S08SH32 Series Features
8-Bit HCS08 Central Processor Unit (CPU)
40-MHz HCS08 CPU (central processor unit) 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 Very low power real time counter for use in run,
wait, and stop
Clock Source Options
Oscillator (XOSC) — 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; 1.5% deviation using internal temperature compensation.
ICS 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
