XC9536-5VQ44C

XC9536-5VQ44C Description

The XC9536-5VQ44C is a 5V Complex Programmable Logic Device (CPLD) from AMD's XC9500 series, offering 36 macrocells and 800 equivalent gates in a compact 44-pin VQFP package. Designed for surface-mount applications, it operates within a 4.75V to 5.25V supply range and delivers a maximum propagation delay (tpd) of 5 ns, making it suitable for high-speed logic implementations. With 34 I/O pins and 2 logic blocks, it provides flexible routing and efficient resource utilization. This device supports in-system programmability (ISP) with a minimum of 10,000 program/erase cycles, enabling field upgrades and rapid prototyping. Although marked as obsolete, it remains relevant for legacy systems due to its reliability and performance.
