• Boundary-scan testing applications supporting IEEE Std. 1149.1

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'AU100' against official documentation to confirm the 100-lead TQFP package and industrial temperature rating (-40°C to +85°C). Ensure design files account for the 3.0V–3.6V VCC operating range and verify JTAG pin configurations if boundary-scan or ISP functions are utilized.

Complex Programmable Logic Devices Selection Notes

Select this component for designs requiring high-density logic in a small form factor with low-power standby capabilities. The 'L' variant provides reduced power consumption compared to standard versions. Ensure the application voltage stays within 3.0V to 3.6V and consider the 20 ns delay when designing for speeds approaching 83.3 MHz.

Complex Programmable Logic Devices Part Context

This part belongs to the ATF1508ASV(L) family of EEPLDs. It shares architectural features such as enhanced routing resources and global control signals with other variants like the ATF1508ASVL-20JU84 (84-lead PLCC) and ATF1508AS-15QC100 (100-lead PQFP), differing primarily in package type, speed grade, and operating voltage.
