Procurement Notes

This component is officially classified as obsolete by the manufacturer and is no longer in active production. Sourcing requires careful verification of part authenticity and condition. Buyers should prioritize authorized distributors or certified secondary market suppliers to ensure reliability. Due to the end-of-life status, long-term availability cannot be guaranteed, making it suitable only for maintenance or non-critical replacement scenarios where lifecycle stability is not required.

Selection Notes

Engineers selecting this part must account for its obsolete status when designing new products. The 208-pin BFQFP package requires specific PCB footprint considerations. While the 3.3V logic level is standard, the limited macrocell count may restrict complexity compared to newer FPGA alternatives. Designers should verify that the 9ns delay meets timing requirements for their specific clock frequencies before committing to this legacy component.

Part Context

The XCR3384XL-10PQ208C is part of AMD's (formerly Xilinx) CoolRunner XPLA3 series, which was designed for mid-range CPLD applications. This family offered a balance of density and speed for general-purpose logic needs. As a legacy product, it represents an earlier generation of programmable logic technology, preceding more advanced high-density solutions currently available in the market.

Replacement Considerations

Public confirmed substitute part numbers are not available in official documentation. The T13F256C3 is listed as a similar alternative but lacks verified functional equivalence data. Engineers should consult AMD's official obsolescence notices for recommended modern replacements or perform full electrical and pin-compatibility analysis before considering any cross-reference.
