ATV2500BL-20KI

Complex Programmable Logic Devices Overview

The ATV2500BL-20KI is a high-density UV-erasable programmable logic device (PLD) manufactured by Microchip Technology. It features a fully connected logic array with 416 product terms and 24 macrocells, providing 48 flip-flops. The device operates at a maximum clock frequency of 40 MHz with a typical pin-to-pin delay of 20 ns. It utilizes a 5V power supply and supports an industrial operating temperature range from -40°C to +85°C. The component is housed in a 44-lead Plastic J-leaded Chip Carrier (PLCC) package.

Complex Programmable Logic Devices Feature Summary

• High-performance UV-erasable PLD with 7 ns typical pin-to-pin delay and 416 product terms
• Flexible output macrocell structure with 48 individually selectable D- or T-type flip-flops
• Low standby power consumption of 2 mA typical at commercial temperatures
• Backward compatible with ATV2500H/L software for design reuse

Complex Programmable Logic Devices Applications

• Complex digital logic replacement in industrial control systems
• State machine implementation requiring independent clocking per register
• Bi-directional I/O bus compatibility designs
• Prototyping and final production for high-density logic applications

Complex Programmable Logic Devices Procurement Notes

Verify the ordering suffix KI corresponds to the Industrial temperature range (-40°C to +85°C) and the 44J PLCC package. Confirm RoHS compliance status as the datasheet indicates non-compliance for standard versions. Ensure UV erasure capabilities are accounted for in storage and handling procedures due to the windowed ceramic variants in the family, though this specific plastic package variant does not require window protection.

Complex Programmable Logic Devices Selection Notes

Select the ATV2500BL-20KI for designs requiring low power consumption compared to the standard ATV2500B series. The 'L' suffix denotes the low-power variant with 2 mA standby current. Ensure the design fits within the 24 macrocell limit and 416 product term capacity. Verify that the 44-lead PLCC package footprint matches the PCB layout requirements.

Complex Programmable Logic Devices Part Context

This component belongs to the ATV2500B family of high-speed, high-density UV EPROM PLDs. It serves as a successor to the ATV2500H/L series, offering enhanced flexibility with selectable D/T flip-flops and buried combinatorial feedback. The BL variant specifically targets power-sensitive applications while maintaining backward compatibility with existing H/L design files.

Complex Programmable Logic Devices Replacement Considerations

The ATV2500BL-20KI can functionally replace the ATV2500H/L series devices using compatible JEDEC files. Direct pin-compatible replacements within the same speed grade include other ATV2500BL variants with different packages, such as ATV2500BL-20JI (PLCC) or ATV2500BL-20KM (Ceramic JLCC), provided temperature ranges align.
