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
