MCHPATF1504ASL-25AU100
Overview
The ATF1504ASL-25AU100 is a high-performance, 5V complex programmable logic device (CPLD) utilizing Microchip's high-density EEPROM technology. It features 64 macrocells and provides a 25 ns maximum propagation delay with advanced power management options, including a 10 uA standby current mode. This device is designed for 5V systems requiring in-system programmability (ISP) and flexible logic routing.
Why Choose This Part
This CPLD offers 5V native operation which eliminates the need for level shifters in older system architectures. Its in-system programmability via JTAG and 10,000 minimum erase/write cycles facilitate easy firmware updates and rapid prototyping. Additionally, the device supports IEEE 1149.1 boundary-scan testing to simplify board-level debugging and manufacturing test coverage.
Applications
Key Specifications
Getting Started
Programming is performed via the JTAG interface using Microchip's ATF15xx family ISP software and a compatible JTAG programmer. Hardware designers should refer to the 100-TQFP footprint requirements and ensure proper decoupling of the 4.5V to 5.5V supply rails. Logic designs can be developed using standard HDL or schematic entry tools that support the ATF15xx series.
