Lifecycle

Status Mature legacy device. Availability can be limited due to age and RoHS non-compliance. Not recommended for new designs in most applications.

Equivalents or alternatives Depending on your FPGA and board design, possible functional alternatives include

- AMD Xilinx Platform Flash families such as XCF series or XC18V series requires design and pinout changes not drop-in

- Microchip Atmel AT17 series configuration memories for legacy Xilinx FPGAs for example AT17LV128 package and pinout compatibility must be verified

- Using external SPI Flash supported by newer FPGA families requires redesign

Important note Alternatives are often not pin-to-pin compatible and may require updates to the board, power-up sequence, and configuration mode. To choose the safest replacement, please contact our sales and engineering team via our website for a detailed cross-check on your exact FPGA and board constraints.

Key Application Areas

Boot configuration storage for legacy AMD Xilinx FPGAs that load bitstreams from serial PROM

Industrial control, test and measurement, medical, telecom, and networking systems with long service lifetimes

Maintenance and repair of installed equipment that originally used XC17xxE PROMs

Rugged and embedded systems needing deterministic power-up down to -40°C
