MC9S08SH32 MC9S08SH16 Data Sheet HCS08 Microcontrollers MC9S08SH32 Rev. 3 3/2014 freescale.com 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 Development Support ...
