S9S08SG4E2VTJ NXP 8-Bit HCS08 Central Processor Unit (CPU) • 40 MHz HCS08 CPU (central processor unit) • 36 MHz HCS08 CPU for temperatures greater than 125 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) Power-Saving Modes • Two very low power stop modes • Reduced power wait mode • Very low power real time interrupt 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 16MHz • 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 1.5% deviation over temperature –40 to 125 C or 3% deviation for temperature > 125 C and voltage; supports bus frequencies from 2 MHz to 20MHz. 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
