Figure 1. EP220 & EP224 Block Diagram
The EP220 and EP224 architecture is based on a sum-of-products,
programmable-AND/fixed-OR structure. Each macrocell can be
individually programmed for combinatorial or registered output. An
inversion option allows each output to be configured for active-high or
active-low operation. Each I/O pin can be programmed to function as an
input, output, or bidirectional pin.
The EP220 and EP224 device architecture offers the following features:
Numbers in parentheses refer to the pin-out number.
