MC9S08SH4CPJ                            Description

The MC9S08SH8 members of the low-cost, high-performance HCS08 Family of 8-bit microcontroller units (MCUs). All MCUs in the family use the enhanced HCS08 core and are available with a variety of modules, memory sizes, memory types, and package types.

MC9S08SH4CPJ                       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)

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) — 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 2 MHz to 20 MHz.

System Protection

? Watchdog computer operating properly (COP)

reset with opti/n 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

? Single-wire background debug interface

? Breakpoint capability to allow single breakpoint

setting during in-circuit debugging (pluss two

more breakpoints in on-chip debug module)

? On-chip, in-circuit emulation (ICE) debug module

containing two comparators and nine trigger

modes. Eight deep FIFO for storing

change-of-flow address and event-only data.

Debug module supports both tag and force

breakpoints.
