General Description
The EPROM-based EP220 and EP224 devices feature a flexible I/O architecture and implement 150 usable (300 available) gates of custom user logic functions. EP220 and EP224 devices can be used as upgrades for high-speed bipolar programmable logic devices (PLDs) or for 74-series LS and CMOS (SSI and MSI) logic devices in high-performance microcomputer systems.
Compared to bipolar devices of equivalent speed, the EP220 and EP224 offer lower power consumption, faster input-to-nonregistered-output delay (tPD) in combinatorial mode, and higher counter frequencies in registered applications. This added performance supports faster state machine designs compared to bipolar devices, and provides additional timing margin for existing designs. The EP220 and EP224 are ideal for high-volume manufacturing of high-performance systems. These devices improve performance and decrease system noise, power consumption, and heat generation.
