1.2 Introduction

The MC68HC908BD48 is a member of the low-cost, high-performance

M68HC08 Family of 8-bit microcontroller units (MCUs). The M68HC08

Family is based on the customer-specified integrated circuit (CSIC)

design strategy. 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.

With special modules such as the sync processor, analog-to-digital

converter, pulse modulator module, DDC12AB interface, multi-master

IIC interface, and universal serial bus interface, the MC68HC908BD48

is designed specifically for use in digital monitor systems.

1.3 Features

Features of the MC68HC908BD48 MCU include the following:

•

High-performance M68HC08 architecture

•

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

M68HC05 families
