XC9536-10PC44C

XC9536-10PC44C Description

The XC9536-10PC44C is a Complex Programmable Logic Device (CPLD) from AMD's XC9500 series, offering 36 macrocells and 800 equivalent gates in a 44-pin PLCC package. Designed for surface-mount applications, it operates within a 5V supply range (4.75V–5.25V) and delivers a maximum propagation delay of 10 ns, making it suitable for high-speed logic implementations. This obsolete but robust CPLD supports in-system programmability (ISP) with a minimum endurance of 10,000 program/erase cycles, enabling flexible field updates. With 34 I/O pins and 2 logic blocks, it balances density and performance for mid-range designs.
