ATF1500A-10AC

Overview

The ATF1500A-10AC is a high-performance, high-density Electrically-Erasable Complex Programmable Logic Device (EEPLD) manufactured by Microchip Technology. It features 32 logic macrocells and supports up to 36 inputs with a maximum pin-to-pin delay of 10 ns. The device operates on a 5V supply and utilizes advanced Flash technology for complete reprogrammability. It offers registered operation speeds up to 76.9 MHz and includes flexible macrocell configurations with global and regional bus architectures.

Feature Summary

• High-density architecture with 32 macrocells and 44 pins (32 I/O, 4 dedicated inputs).
• Advanced Flash technology enabling 100% testing, full reprogrammability, and 20-year data retention.
• Flexible macrocell design supporting D/T/Latch flip-flops and programmable output slew rates.
• Built-in power management with automatic standby mode and optional pin-controlled power-down.

Applications

• Logic integration replacing TTL, SSI, MSI, and classic PLDs.
• State machine implementation utilizing power-up reset features.
• System noise reduction via individually programmable output slew rate control.

Procurement Notes

Verify the specific speed grade suffix (-10) and package type (AC denotes TQFP) against current availability. Confirm RoHS compliance status as standard packages may differ from Green options. Check for obsolescence notices or time-buy dates associated with this component series.

Selection Notes

Select the ATF1500A-10AC for designs requiring 10 ns propagation delay in a commercial temperature range (0°C to 70°C). Ensure the application fits within the 32 macrocell limit and utilizes the 5V ±5% supply specification. Consider the ATF1500AL variant if lower standby current (3 mA) is required.

Part Context

This component belongs to the ATF1500A family of EEPLDs, which are backward compatible with earlier ATF1500/L software and hardware. The 'AC' suffix indicates a 44-lead Thin Plastic Gull Wing Quad Flatpack (TQFP) package suitable for surface mount applications.

Replacement Considerations

For the -7 speed grade, the ATF1502AS is a pin-compatible replacement. For other grades, suggested replacements are available in Green packages. Verify pin compatibility and electrical parameters before substitution.
