XC9572-7PC44C Description

The XC9572-7PC44C is a Complex Programmable Logic Device (CPLD) from AMD's XC9500 series, designed for high-performance digital logic applications. This 72-macrocell device operates at a 7.5 ns propagation delay, making it suitable for timing-critical designs. It features 34 I/O pins and 4 logic blocks, providing flexible integration for medium-complexity circuits. With an internal supply voltage range of 4.75V to 5.25V, it is optimized for 5V systems. The device supports in-system programmability (ISP) with a minimum of 10,000 program/erase cycles, enabling field upgrades and rapid prototyping. Packaged in a 44-pin PLCC (Plastic Leaded Chip Carrier), it is ideal for surface-mount applications in industrial and commercial environments.
