MC9RS08KB2CSC Datasheet PDF - Freescale Semiconductor

MC9RS08KB12 Series

• 8-Bit RS08 Central Processor Unit (CPU)
   – Up to 20 MHz CPU at 1.8 V to 5.5 V across temperature
      range of –40 °C to 85 °C
   – Subset of HC08 instruction set with added BGND
      instruction
   – Single Global interrupt vector
• On-Chip Memory
   – Up to 12 KB flash read/program/erase over full
      operating voltage and temperature,
      12 KB/8 KB/4 KB/2 KB flash are optional
   – Up to 254-byte random-access memory (RAM),
      254-byte/126-byte RAM are optional
   – Security circuitry to prevent unauthorized access to flash
      contents
• Power-Saving Modes
   – Wait mode — CPU shuts down; system clocks continue
      to run; full voltage regulation
   – Stop mode — CPU shuts down; system clocks are
      stopped; voltage regulator in standby
   – Wakeup from power-saving modes using RTI, KBI,
      ADC, ACMP, SCI and LVD
• Clock Source Options
   – Oscillator (XOSC) — Loop-control Pierce oscillator;
      crystal or ceramic resonator range of 31.25 kHz to
      39.0625 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;
      supporting bus frequencies up to 10 MHz
• System Protection
   – Watchdog computer operating properly (COP) reset
      with option to run from dedicated 1 kHz internal low
      power oscillator
   – Low-voltage detection with reset or interrupt
   – Illegal opcode detection with reset
   – Illegal address detection with reset
   – Flash-block protection
• Development Support
   – Single-wire background debug interface
   – Breakpoint capability to allow single breakpoint setting
      during in-circuit debugging
