Overview

The ATF1504ASV-15AU44 is a high-performance 64-macrocell Complex Programmable Logic Device (CPLD) designed for 3.3V low-voltage operations. It utilizes Atmel's High-density PLD technology to provide predictable timing and a flexible logic structure, making it ideal for replacing multiple discrete logic chips or small PLDs.

Why Choose This Part

This CPLD features In-System Programmability (ISP) via a standard JTAG interface, allowing for easy updates without removing the chip. It offers flexible macrocell configurations with D/T/Latch flip-flops and individual output enables, paired with a pin-controlled standby mode for power efficiency.

Applications

I/O Expansion
Adding extra digital I/O pins and logic to microcontrollers with limited peripheral counts.
Glue Logic
Consolidating multiple 74-series logic gates, flip-flops, and decoders into a single small TQFP package.
Voltage Level Shifting
Interfacing between different logic voltage domains in mixed-signal embedded systems.
Custom Timing Generation
Creating precise clock dividers, PWM signals, or state machines that operate independently of the CPU.
