Lattice iCE40LM Family

iCE40LM Family

iCE40LM™ is an ultra-low power FPGA and sensor manager designed for ultra-low power mobile applications, such as smartphones, tablets and handheld devices. The iCE40LM family includes integrated SPI and I²C blocks to interface with virtually all mobile sensors and application processors. The iCE40LM family also features two Strobe Generators that can generate strobes in microsecond ranges with the LowPower Strobe Generator and in nanosecond ranges with the High-Speed Strobe Generator. In addition, the iCE40LM family of devices includes logic to perform other functions such as mobile bridging, antenna tuning, GPIO expansion, motion/gesture recognition, IR remote control, bar code emulation, and other custom functions. The iCE40LM family features three device densities, from 1100 to 3520 Look Up Tables (LUTs) of logic with programmable I/Os that can be used as either SPI/I²C interface ports or general purpose I/Os. It also has up to 80 kbit of Block RAMs to work with user logic.
