iCE40 Ultra / Ultra Lite

Industry-Leading Small Footprint, Low Power FPGA for High Volume Applications

Related Products

World’s Most Popular Low Power FPGA – The iCE40 family has been designed into multiple generations of high-volume applications. Unlike traditional FPGAs, most designs run in the single digit mW power level.

Innovate and Take New Ideas to Market – Why wait to spin new silicon? Add functionality to products today using FPGA logic resources, integrated DSPs and embedded memory blocks at a cost similar to typical ASICs and SOCs.

Free Your Designs From Space Constraints – Ultra small 1.4 mm x 1.4 mm x 0.45 mm WLCSP package removes all barriers to innovation and customization. Available in advanced 0.35 mm pitch package.

Features

  • Flexible logic architecture with up to 3,520 4 input LUTs, up to 26 I/Os for customized interfaces and up to 80 Kbits of embedded distributed memory
  • Ultra-low power advanced process with sleep current as low as 35uA and 1-10 mA active current for most applications
  • High performance signal processing using DSP blocks with multiply and accumulate functions
  • Hardened SPI and I2C blocks to interface to variety of sensors and peripherals
  • FPGA design tools, demos and reference designs to kick start designs
