The cellular infrastructure market has long been a major market for FPGAs, often in conjunction with conventional DSP chips. Such FPGAs have great processing horsepower, but have never been noted for low power consumption. However, Silicon Blue Technologies has introduced what they term as the industry’s first ultra-low power, single-chip, SRAM FPGAs with the highest density, smallest form factor, and lowest cost, providing mobile handheld designers with what the company claims to be "the ultimate combination in portability, flexibility, fastest time to market and ASIC-like costs." The iCE65L04, a 200K-gate version with internal NVM RAM, offers 5µA standby power consumption and 15µA @ 32KHz. The 100K-gate version consumes only 8µA @ 32KHz. Of course, DSP functions are probably out of the question, but the product appears suitable for glue logic and custom circuitry. |
