ICE40LP8K-CM81

Overview

The ICE40LP8K-CM81 is an ultra-low power FPGA from Lattice Semiconductor iCE40 LP series, designed for power-sensitive mobile and handheld applications. It features 7680 logic cells and 128 Kbits of embedded RAM in a compact 4x4 mm 81-VFBGA package. This device is optimized for offloading timing-critical or repetitive tasks from a primary processor to reduce overall system power consumption.

Why Choose This Part

The iCE40LP series is renowned for its industry-leading low power consumption, enabling FPGA functionality in devices with strict thermal and battery constraints. Its small 81-ball BGA footprint is ideal for space-constrained PCB designs while providing 63 user I/O. Additionally, the architecture is supported by an open-source toolchain, allowing for flexible development workflows.

Applications

Getting Started

Developers can use the Lattice iCEcube2 software for synthesis and routing, or leverage the open-source IceStorm toolchain (Yosys and Arachne-pnr/nextpnr). For hardware evaluation, the iCE40HX8K-B-EVN evaluation board provides a similar high-density logic environment. Programming is typically performed via an external SPI Flash or a dedicated SPI interface from a host microcontroller.
