BASIC ARCHITECTURE

To improve total system throughput and reduce component count, board size, and cost of system implementation, the MC68EZ328 combines a powerful MC68EC000 processor with intelligent peripheral modules and a typical system interface logic. The architecture of the MC68EZ328 consists of the following blocks:

• EC000 core

• Chip-select logic and bus interface

• Phase-locked loop and power control

• Interrupt controller

• Parallel general-purpose I/O ports

• Pulse-width modulator

• General-purpose timer

• Serial peripheral interface

• UART and infra-red communication support

• LCD controller

• Real-time clock

• DRAM controller

• In-circuit emulation module

• Bootstrap mode
