EPF10K50RC240-4N

EPF10K50RC240-4N is an Actel (now Microchip) antifuse FPGA from the EPF/10K family. It is a non-volatile, one-time-programmable device built with antifuse technology, meaning its configuration is permanently burnt in during programming. The “10K50” indicates roughly ten-thousand logic/element resources, with a 240-pin RC-style package and the “-4N” denoting a speed grade.
Key points:
- Non-volatile, one-time programmable (revenge programming not possible in the field).
- Fabric supports logic elements, I/O, and embedded memory/routing for moderate-density designs.
- Suitable for rugged, radiation-tolerant environments common in aerospace/defense, where non-volatility and reliability are important.
- Programming typically uses Actel design tools (e.g., Libero/Designer era) and a programmer to blow antifuses.
- Less flexible than flash/SRAM-based FPGAs; newer devices offer reprogrammability and larger resources.
Use when you need a radiation-tolerant, non-volatile FPGA with fixed configuration; consider newer options if field reconfiguration is required.
