ATF2500C-20PI

Complex Programmable Logic Devices Overview

The ATF2500C-20PI is a high-performance, electrically-erasable programmable logic device (PLD) manufactured by Microchip Technology. It features a fully connected logic array with 416 product terms and 24 flexible output macrocells. The component supports up to 48 flip-flops per macrocell and offers a maximum pin-to-pin delay of 20 ns for 5V operation. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 40-pin Plastic Dual Inline Package (PDIP).

Complex Programmable Logic Devices Feature Summary

• High-density architecture with 416 product terms and 24 macrocells.
• Flexible register configuration allowing individual D-type or T-type selection.
• Supports both registered and combinatorial internal feedback paths.
• Includes programmable Pin-keeper circuits and a security fuse feature.

Complex Programmable Logic Devices Applications

• Complex state machine implementations requiring multiple clock domains.
• Bus interfacing applications utilizing the Pin-keeper input option.
• Direct replacement for legacy ATV2500B/BQ and ATV2500H designs.

Complex Programmable Logic Devices Procurement Notes

Verify that the specific ordering suffix matches the required package type and operating temperature range. Confirm RoHS compliance status if lead-free requirements are mandatory, as standard versions may differ from Green package options. Ensure design files are compiled using the correct device mnemonic in Atmel-WinCUPL software.

Complex Programmable Logic Devices Selection Notes

Select this model when a 40-pin through-hole form factor is necessary for industrial environments (-40°C to +85°C). The 20 ns speed grade provides a balance between performance and power consumption. Consider the PLCC variant if surface mount technology is preferred for the same electrical characteristics.

Complex Programmable Logic Devices Part Context

This component belongs to the ATF2500C CPLD family, which utilizes advanced electrically-erasable CMOS technology. The device is functionally equivalent to the ATV2500B/BQ and ATV2500H series, ensuring backward compatibility with existing JEDEC files and design tools while offering higher density and flexibility.

Complex Programmable Logic Devices Replacement Considerations

The ATF2500C-20PI serves as a direct functional replacement for the ATV2500B-20PI and ATV2500H-20PI. Designers migrating from these legacy parts should utilize the cross-programming JEDEC file modes supported by third-party programmers to maintain compatibility.
