A line of new ultra-low-density iCE40TM FPGAs deliver flexible, single-chip sensor solutions for making a new generation of context-aware, ultra-low-power mobile devices possible. The new additions to the iCE40 FPGA family from Lattice Semiconductor allow customers to integrate more functions into a smaller space. In packages as small as 1.4 mm x 1.48 mm x 0.45 mm, they are small enough and affordable enough to fit almost anywhere, reducing board space and system complexity.

With hard IP for strobe generators, I2C and SPI interfaces, the new iCE40LM FPGAs deliver near-zero latency to the mobile market, enabling context-aware systems with the real-time capturing of user and environmental inputs with minimal delay or error. This gives designers a platform for their mobile products to deliver media-rich experiences based on movement, travel direction, location and other interactions with the environment.

The small size of the new iCE40 FPGAs enables integration of advanced functions such as IrDA, barcode emulation, service LED and more in a single chip with available logic for additional customer-defined functions. Moreover, Lattice has demonstrated that the iCE40LM FPGA solution can reduce power consumption by 100x over traditional application processor-only implementations, thus increasing battery life to bring more value to the end user.

The new iCE40LM FPGAs give mobile device system architects the ability to add and/or customize sensor management functions and capabilities using a single, simple platform that can be implemented across different designs. The new additions include the iCE40LM 4K, iCE40LM 2K, iCE40LM 1K FPGAs and consume very little power, under 1 mW in active mode.

All iCE40 devices are supported by the company’s iCEcube2 design software (release 2013-08) and Lattice Diamond Programmer v3.0. Designed to offer a highly productive, integrated development environment for the mobile designer and optimized for Lattice’s iCE40 FPGA architecture, the easy-to-use iCEcube2 software is a world class design flow for the mobile designer. The Lattice Diamond Programmer is compatible with iCEcube2 software and enables device programming for Lattice devices, simplifying the most common steps, including: setting up device information (cable, port etc); selecting the programming data file to use; and programming single or multiple devices.
