iCE40 Ultra family is an ultra-low power FPGA and sensor manager designed for ultra-low power mobile applications, such as smartphones, tablets and hand-held devices. The iCE40 Ultra family includes integrated SPI and I2C blocks to interface with virtually all mobile sensors and application processors. The iCE40 Ultra 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. The iCE40 Ultra family also features DSP functional block to off-load Application Processor to pre-process information sent from the mobile sensors.
