MCHPATF1508AS
Overview
The ATF1508AS is a high-performance, high-density Complex Programmable Logic Device (CPLD) utilizing Electrically Erasable (EE) technology. It features 128 macrocells with a 7.5 ns maximum pin-to-pin delay and supports up to 80 I/O pins in a 100-TQFP package. Operating at a 5V internal supply, it provides a robust solution for legacy logic consolidation and high-speed glue logic applications.
Why Choose This Part
The device offers excellent logic flexibility with 5 product terms per macrocell that are expandable up to 40, allowing for complex combinatorial logic. It supports In-System Programming (ISP) with a minimum of 10,000 erase/write cycles and includes advanced power management features like a 10 uA standby mode in the L-version and a pin-controlled 1 mA standby mode.
Applications
Key Specifications
Getting Started
Designers typically use Microchip WinCUPL or third-party synthesis tools to develop logic using VHDL or Verilog. Programming is achieved through the JTAG interface using a standard ISP cable and compatible hardware programmers like the Atmel-ICE. Ensure the 5V supply (4.75V to 5.25V) is stable and bypassed correctly near the TQFP-100 power pins.
