ATV2500BQ-25KI

Complex Programmable Logic Devices Overview

The ATV2500BQ-25KI 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 flexible macrocells containing 48 flip-flops. The component operates at a maximum frequency of 31 MHz with a typical pin-to-pin delay of 25 ns. It utilizes a single universal and-or array where all pins and feedback terms are available to every macrocell. The device supports selectable D- or T-type registers, independent clocking, and asynchronous resets. It is housed in a 44-lead Plastic J-leaded Chip Carrier (PLCC) package and functions within an industrial temperature range of -40°C to +85°C.

Complex Programmable Logic Devices Feature Summary

• High-performance UV EPROM PLD with 7 ns typical pin-to-pin delay and 416 product terms.
• Flexible macrocell structure featuring 48 flip-flops (two per macrocell) and 72 sum terms.
• Selectable D- or T-type registers with individual clock and reset product terms for each flip-flop.
• Backward compatible with ATV2500H/L software and offers buried combinatorial feedback options.

Complex Programmable Logic Devices Applications

• Complex digital logic replacement in industrial control systems
• State machine implementation requiring multiple independent clocks
• Prototyping and design verification for custom logic circuits

Complex Programmable Logic Devices Procurement Notes

Verify the ordering suffix KI corresponds to the 44-lead Plastic J-leaded Chip Carrier (PLCC) package and Industrial temperature range (-40°C to +85°C). Confirm that the specific speed grade matches the required timing constraints, as the '25' designation indicates a 25 ns propagation delay. Ensure UV erasure capabilities are accounted for in the manufacturing process if reprogramming is required.

Complex Programmable Logic Devices Selection Notes

Select this component when a high gate count PLD with flexible register configuration is needed. The ATV2500BQ-25KI provides 24 I/O lines and supports both registered and combinatorial outputs. Consider the power consumption differences between standard and low-power variants if system power budgets are tight. Verify compatibility with existing PLD programming tools and JEDEC file formats used for the ATV2500H/L series.

Complex Programmable Logic Devices Part Context

The ATV2500BQ-25KI belongs to the ATV2500B family of high-speed, high-density UV-erasable PLDs. This family includes variations such as the ATV2500B, ATV2500BL, and ATV2500BQL, which differ primarily in power consumption and package types. The device leverages advanced 0.65-micron CMOS EPROM technology to provide high speed and low power while maintaining reprogrammability.

Complex Programmable Logic Devices Replacement Considerations

The ATV2500BQ-25KI can functionally replace the ATV2500H and ATV2500L devices using their respective JEDEC files, provided additional GND connections are made. It serves as a direct speed upgrade or functional replacement within the same package footprint.
