XC95108-20PQ160C

XC95108-20PQ160C Description

The XC95108-20PQ160C is a Complex Programmable Logic Device (CPLD) from AMD's XC9500 series, designed for high-performance digital logic applications. This obsolete but historically significant device integrates 108 macrocells and 6 logic blocks, offering a gate count of 2400 and a maximum propagation delay (tpd) of 20 ns. It operates within a 5V supply voltage range (4.75V–5.25V) and supports in-system programmability (ISP) with a minimum of 10,000 program/erase cycles, making it suitable for iterative development. Packaged in a 160-pin QFP (Quad Flat Package), it features 108 I/O pins and is rated for commercial temperature ranges (0°C to 70°C).
