Lattice Semiconductor Corp. has released what it touts as ultra-low density iCE40 FPGAs delivering the world's most flexible, single-chip sensor solutions for context-aware, ultra-low power mobile devices. The latest offerings, which are small and affordable enough to fit almost anywhere, allow customers to integrate more functions into a smaller footprint, and reduce board space and system complexity, indicated the firm.

With hard IP for strobe generators, I2C and SPI interfaces, the 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 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 by100x over traditional application processor-only implementations, thus increasing battery life to bring more value to the end user.

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

Meanwhile, the iCE40LP FPGA product line is being expanded through the addition of a 16-ball WLCSP package for both the iCE40LP 640 FPGA and iCE40LP 1K FPGA to further drive down the footprint of the iCE40 family. Critical for 'the internet of things' and 'always-on' applications, the new additions to the iCE40 family are tiny, measuring just 1.4mm x 1.48mm x 0.45 on an advanced 0.35mm ball pitch packaging.

All iCE40 devices are supported by the company's iCEcube2 design software (release 2013-08) and Lattice Diamond Programmer v3.0. 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.

The devices are in production and available through Lattice's distribution partners. Prices start at under $1 dollar in high volume quantities.
