MC9S08SE8CWL            Description

The 8-bit microcontroller architecture is simpler and has an easy to understand programming model. It usually needs just a single supply. Despite marketing claims to the contrary, modern 8-bit architectures are lower power compared to 32-bit because the innards toggle fewer bus signals.

MC9S08SE8CWL            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

? Peripherals
