ATF1504AS-15QC100

Complex Programmable Logic Devices Overview

The ATF1504AS-15QC100 is a high-performance, high-density Complex Programmable Logic Device (CPLD) manufactured by Microchip Technology. It features 64 macrocells with up to 40 product terms per macrocell and supports 100 pins in a PQFP package. The device operates at a maximum pin-to-pin delay of 15 ns and supports registered operation up to 76.9 MHz. It utilizes electrically-erasable memory technology, offering In-System Programmability (ISP) via JTAG, 10,000 program/erase cycles, and 20-year data retention. The component supports both 3.3V and 5.0V I/O configurations.

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'QC100' against official Microchip documentation to confirm the exact temperature range and voltage specifications for this variant. Ensure design files account for the 100-lead PQFP package dimensions and pinout configuration during procurement planning.

Complex Programmable Logic Devices Selection Notes

Select this component when designs require 64 macrocells with high-speed performance (15 ns delay). Consider the 100-lead PQFP package if surface-mount space allows. Verify compatibility with 3.3V or 5.0V supply rails as supported by the AS series architecture.

Complex Programmable Logic Devices Part Context

This part belongs to the ATF1504AS/L family of Electrically-Erasable PLDs. It shares architectural features with other variants in the series, such as the ATF1504ASL, but differs in package type and specific speed grades. The 'AS' designation indicates support for both 3.3V and 5.0V I/O levels.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements within the same family include ATF1504ASL-15QC100 for leaded versions or other speed grades like ATF1504AS-10QC100 if higher speed is required. Cross-vendor equivalents are not explicitly documented in the provided source material.
