iCE40LM Family Data Sheet DS1045 Version 1.5, March 2015iCE40LM Family Data Sheet Introduction January 2014 Data Sheet DS1045 General Description iCE40LM family is an ultra-low power FPGA and sensor manager designed for ultra-low power mobile applications, such as 2 smartphones, tablets and hand-held devices. The iCE40LM family includes integrated SPI & I C blocks to interface with vir- tually all mobile sensors and application processors. The iCE40LM family also features two Strobe Generators that can generates strobes in Microsecond ranges with the Low-Power Strobe Generator, and also generates strobes in Nanosec- ond 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 tun- ing, 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 2 I/Os that can be used as either SPI/I C interface ports or general purpose I/Os. It also has up to 80 kbits of Block RAMs to work with user logic.
