LSCCiCE40HX4K-BG121

Overview

The iCE40HX4K-BG121 is a smaller-capacity member of Lattice Semiconductor's iCE40 HX FPGA family intended for cost- and resource-constrained designs. It provides a low-power, flexible programmable fabric in the HX package family so you can scale between capacities while keeping similar packaging. The device is suited where simple logic, protocol adaptation, or small hardware accelerators are required without the cost or footprint of larger FPGAs.

Why Choose This Part

Choose the iCE40HX4K-BG121 when you need the flexibility of FPGA logic but must minimize cost, power, or resource usage. It lets you implement custom timing, simple parallel datapaths, or protocol conversion in a compact package and is useful when the larger iCE40 HX devices are overkill. Staying within the iCE40 HX package family makes it easier to scale to higher-capacity parts if your design grows.

Applications

Getting Started

For open-source flows, the iCE40 family is well supported by Project IceStorm (Yosys for synthesis, nextpnr for place-and-route). For commercial support check Lattice's official tools and documentation (consult Lattice Semiconductor for the current recommended toolchain). Because BG121 is a BGA package, development is easiest with a breakout/carrier board or an evaluation/modular board that ships the FPGA pre-mounted; for hand assembly or prototypes consider modules or contract PCB assembly.
