ATF2500C-15JC

Complex Programmable Logic Devices Overview

The ATF2500C-15JC is a high-performance, electrically-erasable programmable logic device (PLD) from the ATF2500C family. It features a fully connected logic array with 416 product terms and 24 flexible output macrocells. The device supports up to 48 flip-flops per macrocell and operates at a maximum pin-to-pin delay of 15 ns for 5V operation. It utilizes advanced electrically-erasable technology, offering reprogrammability and 100% testing. The component is housed in a 44-lead Plastic J-leaded Chip Carrier (PLCC) package and is designed for commercial temperature ranges.

Complex Programmable Logic Devices Feature Summary

• Maximum 15 ns pin-to-pin delay at 5V operation
• Flexible macrocell structure supporting D- or T-type flip-flops
• Backward compatible with ATV2500B/BQ and ATV2500H software

Complex Programmable Logic Devices Applications

• Complex digital logic replacement
• Bus interfacing applications utilizing Pin-keeper circuits
• State machine implementations with independent clocking

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'JC' corresponds to the 44-lead PLCC package and Commercial temperature range (0°C to 70°C). Confirm RoHS compliance status as standard packages may differ from Green Package Options. Ensure design files are compiled using the correct device mnemonic (V2500C or V2500CPPK) to enable or disable Pin-keeper features appropriately.

Complex Programmable Logic Devices Selection Notes

Select the ATF2500C-15JC when a 15 ns propagation delay is required within the commercial temperature range. Consider the ATF2500C-20JC if a slower speed grade is acceptable but cost optimization is needed. Verify that the 44-lead PLCC footprint matches the target PCB layout. Check if military or industrial temperature grades are necessary for the application environment.

Complex Programmable Logic Devices Part Context

The ATF2500C series represents a high-density PLD solution from Atmel (now Microchip Technology). It is functionally equivalent to the ATV2500B/BQ and ATV2500H families, allowing for direct software migration. The device is part of the CPLD/SPLD category, offering high gate utilization through its fully connected logic array and flexible macrocell design.

Complex Programmable Logic Devices Replacement Considerations

The ATF2500C is a direct functional replacement for the ATV2500B, ATV2500BQ, and ATV2500H devices. When replacing these older parts, ensure the JEDEC file type is selected correctly in the programming software to maintain compatibility with existing fuse patterns and feature sets.
