Overview

The ATF1504AS-7AX44 is a high-performance 64-macrocell Complex Programmable Logic Device (CPLD) utilizing Microchip's proprietary Electrically Erasable (EE) technology. Operating at 5V, this device provides a flexible solution for replacing legacy 74-series logic and implementing custom digital state machines with predictable timing.

Why Choose This Part

This CPLD features In-System Programming (ISP) which allows for logic updates without removing the chip from the board. It offers a 7.5ns maximum pin-to-pin delay for high-speed logic operations and provides high-reliability non-volatile memory that does not require an external configuration PROM.

Applications

Legacy Logic Consolidation
Integrating multiple 74-series discrete logic chips into a single package to reduce PCB footprint and complexity.
I/O Expansion
Adding custom GPIO, PWM, or communication interfaces to microcontrollers with limited peripheral sets.
Interface Bridging
Managing timing differences and signal translation between mismatched bus protocols in 5V digital systems.
Address Decoding
Implementing high-speed memory mapping and chip-select logic for embedded processor architectures.

Getting Started

Development is supported through Microchip's WinCUPL software or ProChip Designer for VHDL/Verilog synthesis. Programming is typically performed via a standard JTAG interface using a compatible ISP cable or hardware programmer such as the ATDH1150USB.
