MCHPATF1504AS-7AX100
Overview
The ATF1504AS-7AX100 is a high-performance Complex Programmable Logic Device (CPLD) with 64 macrocells and 7.5 ns maximum propagation delay. It operates on a 5V supply and provides in-system programmability with a minimum of 10,000 program/erase cycles. This device is designed for logic integration in legacy 5V systems and high-speed glue logic applications.
Why Choose This Part
It offers 5V operation with low standby and shutdown current of 10uA, making it efficient for power-sensitive 5V designs. The device supports ISP through JTAG, allowing for firmware updates without removing the chip from the PCB. With 64 macrocells and a fast 7.5 ns tpd, it provides reliable performance for high-speed state machines and combinatorial logic.
Applications
Key Specifications
Getting Started
Designers can use Microchip WinCUPL or ATMISP software to develop logic and program the device via the JTAG interface. Hardware implementation requires a 100-TQFP footprint and a stable 4.75V to 5.25V power supply. Ensure proper decoupling capacitors are placed near the VDD pins to handle switching transients common in high-speed CPLDs.
