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
