Overview
The ATF2500C-15JU 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 device supports up to 48 flip-flops per macrocell and offers a maximum pin-to-pin delay of 15 ns for 5V operation. It operates within an industrial temperature range of -40°C to +85°C and utilizes a 44-lead Plastic J-leaded Chip Carrier (PLCC) package.
Feature Summary
- High-density architecture with 416 product terms and 24 macrocells
- Maximum 15 ns propagation delay at 5V supply voltage
- Supports D-type and T-type flip-flops with individual clocking
- Includes programmable pin-keeper circuits and security fuse
Applications
- Complex digital logic replacement in industrial control systems
- State machine implementation with asynchronous reset capabilities
- Bus interfacing utilizing programmable pin-keeper input circuits
Procurement Notes
Verify the specific ordering suffix 'JU' corresponds to the 44-lead PLCC package and Industrial temperature grade (-40°C to +85°C). Confirm RoHS compliance status as Green Package Options are available. Ensure design tools support the V2500 device mnemonic for programming.
Selection Notes
Select this component when a 5V supply is required with a maximum 15 ns delay. The ATF2500C-15JU provides backward compatibility with ATV2500B/BQ software designs. Consider the ATF2500C-20JU if a slower speed grade is acceptable for potential cost or availability variations.
Part Context
The ATF2500C series represents Atmel's highest-density PLD in a 44-pin surface mount package. It utilizes advanced electrically-erasable technology and is functionally equivalent to the ATV2500B/BQ and ATV2500H families. The device allows for flexible design options including buried combinatorial feedback and selectable synchronous/asynchronous clocking.
Replacement Considerations
The ATF2500C-15JU serves as a direct functional replacement for the ATV2500B/BQ and ATV2500H devices. Designers migrating from these legacy parts should utilize the appropriate cross-programming JEDEC file type to ensure compatibility.
