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
