Introduction

The MC68HC908AB32 is a member of the low-cost, high-performance M68HC08 Family of 8-bit microcontroller units (MCUs) with embedded EEPROM for user data storage. All MCUs in the family use the enhanced M68HC08 central processor unit (CPU08) and are available with a variety of modules, memory sizes and types, and package types.

Features

Features of the MC68HC908AB32 include the following:

• High-performance M68HC08 architecture

• Fully upward-compatible object code with M6805, M146805, and

M68HC05 Families

• Memory map and pin functions compatible with MC68HC08AB32

and MC68HC08AB16

• 8-MHz internal bus frequency
