Xilinx XC9572-15TQ100C CPLD Complex Programmable Logic Device

XC9572-15TQ100C Product Overview

The XC9572-15TQ100C is a high-performance CPLD (Complex Programmable Logic Device) from the Xilinx (now AMD) XC9500 series, designed for small-to-medium scale logic control, interface conversion, and communication processing. As a classic member of this series, it is widely used in industrial control, communication equipment, test instruments, and more.

This device comes in a 100-pin TQFP package, offering 72 macrocells, 72 I/O pins, and up to 1600 usable gates, enabling flexible implementation of various digital logic functions. Its 15ns pin-to-pin delay meets the timing requirements of high-speed digital systems.

The XC9572-15TQ100C supports In-System Programmable (ISP) via JTAG boundary scan, allowing programming directly on the circuit board without removing the chip — greatly improving production efficiency and system maintenance convenience. It supports at least 10,000 program/erase cycles, ensuring design flexibility and product lifecycle longevity.

With its 5V operating voltage, wide temperature range (0°C ~ 70°C), and non-volatile memory (configuration retained after power-off), the XC9572-15TQ100C has become an indispensable logic processing core in many legacy industrial equipment and communication systems.
