Overview

The Microchip ATF1502AS-10AU44 is an electrically-erasable Complex Programmable Logic Device (CPLD) featuring 32 macrocells. It is designed for high-density, high-performance applications, offering flexible logic and advanced power management capabilities. This CPLD supports in-system programmability (ISP) and JTAG boundary-scan testing.

Why Choose This Part

Engineers choose this CPLD for its high integration density, combining 32 macrocells in a compact 44-pin TQFP package. The in-system programmability (ISP) feature allows for easy design iteration and field updates, enhancing product lifecycle flexibility. Advanced power management options and reduced-power features per macrocell contribute to energy-efficient designs. Its support for JTAG boundary-scan testing simplifies board-level debugging and manufacturing test processes.
