EP224
EP220 & EP224 Classic EPLDs
Functional
Description
Compared to bipolar devices of equivalent speed, the EP220 and
EP224 offer lower power consumption, faster input-to-non-
registered-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.
Figure 1 shows block diagrams of the EP220 and EP224 device
architectures. The EP220 has 10 dedicated inputs and 8 I/O pins; the
EP224 has 14 dedicated inputs and 8 I/O pins.
