Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized distributors or certified secondary market suppliers. Confirm the presence of RoHS compliance markings and check for moisture sensitivity level (MSL) handling requirements prior to soldering. Ensure the specific suffix matches the required temperature grade and package variant.

Complex Programmable Logic Devices Selection Notes

Select this model when 128 macrocells are sufficient for the design complexity. The 5.5 ns delay meets timing requirements for frequencies up to 175 MHz. Verify that the 144-pin TQFP footprint fits the PCB layout constraints and that the 3V to 3.6V power rail is available.

Complex Programmable Logic Devices Part Context

This part belongs to the AMD CoolRunner XPLA3 family, which bridges the gap between simple PLDs and high-density FPGAs. The XCR3128XL variant specifically offers a balance of density and low power consumption suitable for embedded control applications.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may be limited due to the discontinued status of the XPLA3 line. Evaluate newer generations such as the CoolRunner-II or CoolRunner-XP series for functional equivalence, noting potential differences in I/O standards and programming interfaces.
