Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'QI' against official documentation to confirm package type and temperature range, as datasheet tables list standard variants like 'QC' for PQFP-100 Commercial. Confirm availability status as older Atmel/Microchip CPLD lines may have discontinuation notices. Ensure design tools support the specific device variant for accurate fitting.

Complex Programmable Logic Devices Selection Notes

Select this model for designs requiring 128 macrocells with fast 7.5 ns propagation delay. Choose based on required I/O voltage (3.3V vs 5.0V) and operating temperature range (Commercial vs Industrial). Verify that the 100-pin package fits the PCB layout constraints and that ISP/JTAG programming infrastructure is available.

Complex Programmable Logic Devices Part Context

This part belongs to the ATF1508AS(L) family of high-density EEPLDs. It utilizes Atmel's proven electrically-erasable technology and supports IEEE Std. 1149.1 JTAG boundary-scan testing.
