EPM3512AFC256-10N

EPM3512AFC256-10N Description

The EPM3512AFC256-10N is a high-performance Complex Programmable Logic Device (CPLD) from Intel's MAX® 3000A series, designed for embedded logic applications requiring fast, reliable, and flexible programmability. This obsolete but robust CPLD integrates 512 macrocells and 10,000 gates, delivering a maximum propagation delay of 10 ns, making it suitable for high-speed logic operations. Operating within a 3V to 3.6V internal supply range, it supports 208 I/O pins and features in-system programmability (ISP), enabling field upgrades without physical removal. Packaged in a 256-pin Fine-Pitch Ball Grid Array (FBGA), it is optimized for surface-mount PCB designs.
