XC9572-15PQ100C

Complex Programmable Logic Devices Overview

The XC9572-15PQ100C is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500 family, manufactured using CMOS FastFLASH technology. It features 72 macrocells and 1600 system gates organized into four Logic Array Blocks (LABs). The device operates at a maximum frequency of 55.6 MHz with a typical pin-to-pin propagation delay of 15 ns. It supports in-system programming (ISP) via JTAG with a minimum endurance of 10,000 erase/program cycles. The component is housed in a 100-pin PQFP package and functions within a supply voltage range of 4.75 V to 5.25 V.

Complex Programmable Logic Devices Procurement Notes

This specific part number is listed as obsolete and no longer manufactured by AMD. Verification of authenticity is critical when sourcing from third-party distributors, as the component may be surplus or refurbished. Buyers should confirm the manufacturing date code and physical condition upon receipt. Alternative sources may offer compatible devices from other manufacturers or newer revisions within the same functional family.

Complex Programmable Logic Devices Selection Notes

Designers requiring this specific logic density and I/O count should consider that the XC9572-15PQ100C is end-of-life. Selection of a direct replacement requires matching the 72 macrocell architecture and 100-pin PQFP footprint. Modern alternatives from AMD or competitors may offer higher performance or lower voltage options but will likely require schematic and PCB layout modifications due to differences in pinout or electrical characteristics.

Complex Programmable Logic Devices Part Context

The XC9500 series represents a high-performance non-volatile CPLD family known for its ease of use and in-system programmability. The XC9572 variant provides a balance of logic capacity and I/O flexibility, suitable for mid-range digital control applications. The '15' suffix indicates the speed grade with a 15 ns delay, while 'PQ100' specifies the plastic quad flat pack package with 100 leads.
