What is the LFCPNX-50-8CBG256I and what does it do?
The LFCPNX-50-8CBG256I is a Lattice CertusPro™-NX FPGA with 52K logic elements and 167 user I/Os in a 256-ball WLP package. It targets mid-density designs needing moderate logic, on-chip memory, and a wide I/O count. On-chip block RAM totals 1,769,472 bits, enough for small FIFOs, coefficient tables, or packet buffers without external SRAM. The core supply voltage is 0.95V, which reduces dynamic power but demands a clean, tight-regulation rail — plan the power tree accordingly.
Temperature grade and environment fit
The 256-ball WLP is a wafer-level package — the 0.5mm ball pitch requires a controlled impedance PCB stack-up and X-ray inspection for void-free solder joints.
Production is ongoing.
52K logic elements place this part between small 30K-LE FPGAs and larger 100K-LE devices. For a design that fits in 40K LEs, you have headroom for future tweaks without moving to a bigger package. With 167 I/Os, you can connect a 32-bit parallel bus, a DDR memory interface, and several serial links simultaneously. The I/O count is the binding constraint for interface-heavy boards.
