Overview

The ATF1502ASL-25AU44 is a high-performance, low-power Complex Programmable Logic Device (CPLD) utilizing Microchip's advanced EEPROM technology. It features 32 macrocells and 44 pins in a TQFP package, operating at a 5V logic level with a maximum pin-to-pin delay of 25ns. This 'L' version is specifically designed for power-sensitive applications, offering a 10uA standby mode and a pin-controlled 1mA standby mode.

Why Choose This Part

The device offers In-System Programmability (ISP) via JTAG, allowing for field updates and simplified manufacturing flows. Its flexible macrocell architecture supports up to 40 product terms per macrocell and includes programmable output slew rates and open-collector options to minimize electromagnetic interference.

Applications

Legacy 5V Logic Consolidation
Ideal for replacing multiple 74-series discrete logic gates in 5V systems to reduce PCB footprint and BOM complexity.
Interface Bridging
Used to bridge disparate logic levels or protocols between microprocessors and peripheral hardware.
Power-Sensitive Control Logic
Utilizes the 10uA standby mode for battery-powered industrial equipment requiring occasional logic wake-ups.
I/O Expansion
Provides 32 additional programmable I/O pins with flexible macrocell configurations for complex state machines.

Getting Started

Design entry can be performed using Microchip's WinCUPL or third-party EDA tools that support the ATF15xx family. Programming is achieved through the JTAG interface using a compatible ATDH1150USB or similar ISP programmer. Ensure the 4.5V to 5.5V supply is stable and decoupled for reliable 5V logic operation.

Also Consider

ATF1504ASL-25AU100 MCHPMicrochip Technology - Provides 64 macrocells and more I/O pins if the logic requirements exceed the capacity of the 32-macrocell version.
