iCE40 UltraPlus – ML/AI Low Power FPGA

Low power, edge intelligent FPGA. Lowest power machine learning solution with flexible interfaces.

Low Power Connectivity and Computing – With the rising complexity of systems used to power smart homes, factories and cities, the iCE40 UltraPlus FPGA can solve connectivity issues with a wide variety of interfaces and protocols and provide the low power computational resources for higher levels of intelligence.

Edge Intelligent FPGA – The iCE40 UltraPlus FPGA with 5k lookup tables (LUTs) is able to implement Neural Networks for pattern matching necessary to bring always-on intelligence to the edge. Optimized for best-in-class power, designers can eliminate latency associated with cloud intelligence while keeping the overall system solution cost low.

Flexible Package Options – Multiple package are available to fit a wide range of applications needs. From an ultra-small 2.15 x 2.50 mm WLCSP package optimized for consumer and IoT devices, to a 0.5 mm pitch 7 x 7 mm QFN for cost optimized applications.
