Device Overview

MC9S08DZ128 Series devices are 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.

MC9S08DZ128 Series Features

8-Bit HCS08 Central Processor Unit (CPU)

• 40-MHz HCS08 CPU (20-MHz bus)

• 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; 8-byte single-page or 4-byte dual-page erase sector; Program and Erase while executing FLASH; Erase abort

• 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

• Multi-purpose Clock Generator (MCG) — PLL and FLL modes; reference clock with nonvolatile trim (0.2 resolution, 1.5 tolerance over temperature with internal temperature compensation); External reference with oscillator/resonator options

System Protection

• Watchdog computer operating properly (COP) reset with option to run from backup dedicated 1-kHz internal clock source or bus clock; with optional windowed operation

• 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

• Loss-of-lock protection

Development Support

• Single-wire background debug interface

• On-chip, in-circuit emulation (ICE) with real-time bus capture

Input/Output

• Up to 87 general-purpose input/output (I/O) pins and 1 input-only pin

• Up to 32 interrupt pins with selectable polarity on each pin

• Hysteresis and configurable pull device on all input pins.

• Configurable slew rate and drive strength on all output pins.
