ATF1504ASL-20AC100

Overview

The ATF1504ASL-20AC100 is a high-density, electrically-erasable Complex Programmable Logic Device (CPLD) manufactured by Microchip Technology. It features 64 macrocells with up to 68 inputs and outputs, housed in a 100-pin PQFP package. The device operates at a maximum frequency of 83.3 MHz with a maximum pin-to-pin propagation delay of 20 ns. It utilizes EEPROM technology for non-volatile configuration, supports In-System Programmability (ISP) via JTAG, and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• 64 Macrocells with 5 product terms each, expandable to 40 via cascade logic
• In-System Programmability (ISP) using the standard 4-pin JTAG interface
• EEPROM storage providing 10,000 program/erase cycles and 20-year data retention
• Supports both 3.3V and 5.0V I/O pins with programmable slew rates

Applications

• High-performance control applications requiring complex logic integration
• Digital designs executing boot loader functions
• Loading Field Programmable Gate Array (FPGA) configuration data from non-volatile memory
• Small design applications such as address decoding

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature grade. Confirm that the 'L' designation aligns with the intended power management requirements, as it may indicate specific standby current characteristics compared to the standard variant. Ensure compatibility with existing PCB footprints for the 100-lead PQFP package.

Selection Notes

Select this component when a high gate count CPLD with guaranteed non-volatile storage is required. The 20 ns speed grade offers a balance between performance and power consumption for commercial applications. Consider the enhanced routing resources if pin-locking modifications are anticipated during the design phase. Verify that the 100-pin PQFP package fits the available board space constraints.

Part Context

This part belongs to the ATF1504AS/L family of high-performance CPLDs. The 'AS' indicates the advanced speed and feature set, while 'L' typically denotes low-power variants or specific packaging options within the series. The '100' suffix specifies the 100-lead PQFP package, distinguishing it from TQFP or PLCC alternatives in the same logical family.
