Overview

The ATF1502ASV-15AU44 is a high-performance, low-power Complex Programmable Logic Device (CPLD) featuring 32 macrocells and a 15ns maximum propagation delay. Operating at a 3.3V supply voltage, it utilizes EEPROM technology to provide non-volatile logic configuration with In-System Programmability via a JTAG interface. It is designed to replace discrete TTL logic and smaller PLDs in power-sensitive embedded designs.

Why Choose This Part

This CPLD offers flexible logic routing with improved connectivity and advanced power management, including a reduced-power mode that drops current to 25mA. Its 10,000-cycle EEPROM endurance and 20-year data retention ensure long-term reliability in industrial environments. Additionally, features like programmable pin-keeper inputs and 2000V ESD protection simplify board-level hardware design.

Applications

I/O Expansion
Adding extra digital I/O pins and custom peripheral logic to microcontrollers with limited hardware resources.
Bus Interfacing
Implementing glue logic for PCI-compliant interfaces, address decoding, and bus arbitration between processors and memory.
State Machine Implementation
Executing high-speed, deterministic control sequences for hardware initialization or timing-critical signal management.

Getting Started

Designers can develop for the ATF1502ASV using Microchip WinCUPL or integrated third-party synthesis tools like Precision RTL. Programming is typically handled via a JTAG-compliant hardware interface using the standard IEEE 1149.1 boundary-scan pins. Evaluation can be performed using generic 44-pin TQFP breakout boards or Microchip's dedicated CPLD development kits.
