• Industrial applications necessitating wide temperature range operation.

Complex Programmable Logic Devices Procurement Notes

Verify the specific package type for the 'JI' suffix against official Microchip documentation, as datasheet listings primarily detail PLCC and TQFP options. Confirm current availability status directly with authorized distributors, as component lifecycle stages may vary. Ensure design tools support the specific speed grade and voltage requirements.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 64 macrocells and ISP capabilities within a 3.3V environment. Consider the -15 speed grade for timing constraints under 15 ns. Evaluate power consumption needs, noting that the 'L' variant offers lower standby current if applicable. Verify pin compatibility with existing PCB layouts using the provided pinout tables.

Complex Programmable Logic Devices Part Context

This component belongs to the ATF1504ASV/L family of Complex Programmable Logic Devices. It shares architectural similarities with other members like the ATF1504ASV-15JI44 but differs in package configuration. The series is characterized by its electrically erasable memory technology and JTAG-based programming interface.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements must match the 64 macrocell count, 15 ns speed grade, and 3.3V supply. Check for equivalent packages such as PLCC-44 or TQFP-44 depending on the specific 'JI' package definition. Ensure the substitute supports ISP and industrial temperature ranges.
