ICE40LP4K

Overview

The ICE40LP4K is a Lattice iCE40 LP-series FPGA variant offering larger logic capacity while remaining in the low-power iCE40 family. It is intended for battery-sensitive and compact applications that need user-defined digital logic, interface bridging, or small hardware acceleration without the power or area cost of larger FPGAs. The device is commonly used where low static and dynamic power plus small form factor are priorities.

Why Choose This Part

Choose the ICE40LP4K when your design needs FPGA flexibility but must stay within tight power and size budgets. The iCE40 LP family is known for low static and dynamic power footprints and small-package availability, making it suitable for portable and embedded products. Community-supported open-source toolchains (Project IceStorm, Yosys, nextpnr) plus Lattice documentation and reference material make it practical for both production and open development workflows.

Applications

Getting Started

Start with HDL (Verilog) development and synthesize using the open-source flow: Yosys for synthesis, Project IceStorm for bitstream tooling, and nextpnr for place-and-route; these tools support iCE40 devices and are widely used in the community. Also consult Lattice official documentation and reference designs for device-specific constraints, recommended power sequencing, and IO guidance. For hardware bring-up, use an evaluation or community dev board that exposes iCE40 LP family pins, verify IO voltage levels, and plan proper decoupling and power supply sequencing.
