iCE40LM Family

For ultra-low power mobile applications, such as smartphones, tablets, and handheld devices, the iCE40LM FPGA and sensor management was created. Almost all mobile sensors and application processors can be interfaced with using the integrated SPI and I2C blocks found in the iCE40LM series. The iCE40LM series also includes two strobe generators, the LowPower Strobe Generator and the High-Speed Strobe Generator, which can produce strobes in the microsecond and nanosecond timescales, respectively. The iCE40LM family of devices also includes circuitry for additional tasks like mobile bridging, antenna tuning, GPIO expansion, gesture and motion recognition, IR remote control, bar code emulation, and other specialized tasks.
