Complex Programmable Logic Devices Procurement Notes

Verify the specific ordering suffix 'AC' against official Microchip documentation to confirm commercial versus industrial temperature ratings and package type. Ensure design files account for humidity sensitivity and moisture management requirements during storage and assembly processes.

Complex Programmable Logic Devices Selection Notes

Select this component for designs requiring high density with 128 macrocells and flexible I/O configurations. Consider the enhanced routing resources for successful pin-locked modifications. Verify that the 3.0V to 3.6V operating voltage aligns with the target system's VCCIO and VCCINT supply rails.

Complex Programmable Logic Devices Part Context

This part belongs to the ATF1508ASV(L) family of high-performance EE PLDs. The 'V' suffix indicates a 3.3V-only operating range, distinguishing it from the 5V-compatible ATF1508AS series. The '15' denotes the 15 ns speed grade, while 'A' typically signifies industrial temperature range and 'C' often refers to commercial or specific package variants depending on the manufacturer's coding scheme.

Complex Programmable Logic Devices Replacement Considerations

Direct replacements include other ATF1508ASV variants with different speed grades or package types, such as ATF1508ASV-15AU100-T. Cross-family migration to ATF1508AE or ATF1508ASL may require schematic and logic file adjustments due to voltage or feature differences.

Complex Programmable Logic Devices FAQ

What is the maximum internal global clock frequency?

The maximum internal global clock frequency is 76.9 MHz for the -15 speed grade.

Does the device support boundary-scan testing?

Yes, the ATF1508ASV supports JTAG Boundary-scan Testing (BST) compliant with IEEE Std. 1149.1-1990 and 1149.1a-1993.

How many product terms can be expanded to per macrocell?

Each macrocell has 5 product terms but can be expanded up to 40 product terms using cascade logic between macrocells.
