EP220 & EP224 Classic EPLDs

Compared to bipolar devices of equivalent speed, the EP220 and

EP224 offer lower power consumption, faster input-to-non-

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.
