EPF10K50RC240-3N

EPF10K50RC240-3N is an Actel (now Microsemi/Microchip) antifuse-based FPGA from the EPF family. It is a mid-range device offering about 10K logic gates (per the family naming) in a 240-pin RC package, with a -3N speed grade (industrial temperature range). The device uses non-volatile antifuse configuration memory, so it is programmed once and retains its configuration without external PROM; reconfiguration requires reworking the device. It provides configurable logic blocks, memory resources, flip-flops, and I/O banks suitable for embedded digital designs. Typical advantages include low static power, fast power-up since no external configuration memory is needed, and good radiation-tolerance characteristics for aerospace/industrial applications. Programming is done with Actel’ s programming tools (e.g., Libero/Designer) using an Actel programmer. Note: as an older, OTP FPGA, it has largely been superseded by newer SRAM/flash-based families, but can still be used where compatible tooling and legacy designs matter.

It uses a 240-pin ceramic quad flat-pack (CQFP) package.

- Pin count: 240 pins (RC240 package, 240-pin TQFP)
