MC9S08SE8 Datasheet PDF - NXP Semiconductors.

Features:
• 8-Bit HCS08 Central Processor Unit (CPU)
   – 20 MHz HCS08 CPU (central processor unit)
   – 10 MHz internal bus frequency
   – HC08 instruction set with added BGND
   – Support for up to 32 interrupt/reset sources
• On-Chip Memory
   – Up to 8 KB of on-chip in-circuit programmable flash
   memory with block protection and security options
   – Up to 512 bytes of on-chip RAM
• Power-Saving Modes
   – Wait plus two stops
• 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;
   supports bus frequencies from 1 MHz to 10 MHz.
• System Protection
   – Optional computer operating properly (COP) reset with
   option to run from independent 1 kHz internal clock
   source or the bus clock
   – Low voltage detection
   – Illegal opcode detection with reset
   – Illegal address detection with reset
• Development Support
   – Single-wire background debug interface
   – Breakpoint capability to allow single breakpoint setting
   during in-circuit debugging
