MC9S08EL32 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

? EEPROM in-circuit programmable memory; program and erase while executing FLASH; erase abort

? Random-access memory (RAM)

? Security circuitry to prevent unauthorized access to RAM and NVM contents

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 16 MHz

? Internal clock source (ICS) — Contains 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 2–20 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 and EEPROM block protect

Development Support

? Single-wire background debug interface

? Breakpoint capability allows single breakpoint setting during in-circuit debugging (plus two more breakpoints in the on-chip debug module)

? In-circuit emulation (ICE) debug module — contains two comparators and nine trigger modes; eight-deep FIFO for storing change-of-flow address and event-only data; supports both tag and force breakpoints
