The congested RF environments in high-density cities and rural areas with limited reception can now attain 40 per cent better reception quality with the new ultra-low power FPGA and sensor manager from Lattice. The device is specifically designed for ultra-low power mobile applications, such as smartphones, tablets and hand-held devices.

According to product specification, “The iCE40LM family includes integrated SPI & I2C blocks to interface with virtually all mobile sensors and application processors. It also features two strobe generators that can generate strobes in microsecond ranges with the low-power strobe generator, and also generates strobes 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 1000 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/O’s. It also has up to 80Kbits of Block RAMs to work with user logic.

Adding further, the media release also lays emphasis on the implemetation of iCE40LM in Huawei’s P8 smartphone. The tunable antenna function embedded in iCE40LM helps in attaining 80 per cent faster 4G reception for multiple RF conditions, as claimed by Huawei. The iCE40 LM device performs as the bridge between the Kirin 930 application processor and tuner integrated circuit to minimise latency during an antenna switch, also saving system power.

Further in an interview, Subra Chandramouli, director of marketing for Lattice said, “We designed the iCE40 LM to provide our partners ultimate flexibility when designing consumer devices where space is at a premium. Huawei shows that users do not have to sacrifice functionality when choosing a beautiful device.”
