iCE40HX1K in Lattice iCE40 Family
The iCE40HX1K series is a high-performance, low-density sub-family of the Lattice iCE40 mobile FPGA line. Engineered for low-latency hardware acceleration and high-speed glue logic, these devices utilize a 40nm CMOS process. They provide 1,280 logic cells and support flexible I/O configurations. Designed by Lattice Semiconductor, the HX1K series is a staple for engineers requiring predictable timing and minimal power consumption in compact form factors, bridging the gap between discrete logic and larger FPGAs.

Variants within the iCE40HX1K sub-family are distinguished primarily by packaging and thermal ratings. The VQ100 package offers a 0.5mm pitch TQFP-style layout suitable for hand-soldering and low-cost 2-layer PCBs, whereas the CB132 and CB121 variants utilize fine-pitch BGA footprints for high-density designs. While the silicon fabric remains consistent at 1,280 LUTs, the available user I/O count varies significantly between packages, ranging from 72 to 95 pins.
