XC9572-15PQ100I

XC9572-15PQ100I Description

The XC9572-15PQ100I is a 72-macrocell CPLD (Complex Programmable Logic Device) from AMD's XC9500 series, designed for high-performance digital logic applications. It features an internal voltage supply range of 4.5V to 5.5V, making it compatible with standard 5V systems. With 72 I/O pins and 4 logic blocks, this device offers 1,600 gates and a maximum propagation delay (tpd) of 15 ns, ensuring fast signal processing. The 100-pin QFP (Quad Flat Package) surface-mount design is ideal for space-constrained PCB layouts. Although marked as obsolete, it remains a reliable choice for legacy systems requiring reprogrammable logic with 10K program/erase cycles.
