iCE40 Ultra/UltraLite

Lattice Semiconductor

iCE40 Ultra/UltraLite FPGA Family

iCE40 Ultra™/UltraLite™ family from Lattice Semiconductor is an optimum logic, smallest footprint, low I/O count ultra-low power FPGA and sensor manager. It is designed for ultra-low power mobile applications, such as smartphones, tablets and hand-held devices. The iCE40 Ultra/UltraLite family includes integrated blocks to interface with virtually all mobile sensors and application processors. The iCE40 Ultra/UltraLite family also features two on-chip oscillators, 10 kHz and 48 MHz.
The LFOSC (10 kHz) is ideal for low power function in always-on applications, while HFOSC (48 MHz) can be used for awaken activities.
