• Supports independent I/O paths, buried combinatorial feedback, and selectable synchronous/asynchronous clocking.

Complex Programmable Logic Devices Applications

• Complex digital logic implementation requiring high gate density in a 40-pin package.
• State machine designs utilizing buried registers and independent clock domains.
• Industrial control systems operating within the -40°C to +85°C temperature range.

Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'DI' corresponds to the Industrial temperature range (-40°C to +85°C) and the 40DW6 Cerdip package configuration. Confirm that the required UV erasure equipment is available, as this is a UV-erasable device. Ensure the design accounts for the standby current specifications appropriate for the industrial grade variant.

Complex Programmable Logic Devices Selection Notes

Select the ATV2500BQ-25DI when an industrial temperature rating is required alongside a ceramic dual inline package. This model provides a 7 ns typical delay and 31 MHz external feedback maximum frequency. Compare against commercial variants if the application environment remains within 0°C to 70°C, or consider lower speed grades if power consumption is a primary constraint.

Complex Programmable Logic Devices Part Context

This component belongs to the ATV2500B family of high-speed, high-density PLDs. It serves as a backward-compatible upgrade to the ATV2500H/L series, offering enhanced features such as T-type flip-flops and direct input pin clocking. The 'BQ' designation indicates the inclusion of additional ground connections compared to the standard B series, improving noise immunity.

Complex Programmable Logic Devices Replacement Considerations

The ATV2500B-25DI is a functional equivalent within the same package type but lacks the enhanced ground connections of the BQ series. Direct replacement requires verifying that the additional GND pins on the BQ version are not utilized in the original circuit design.
