In July 2011, Energy Micro announced the availability of its EFM32 Gecko and Tiny Gecko product lines in a QFP64 package. The new 64-pin devices are particularly popular in the growing smart metering market, in addition to energy sensitive applications like building automation, security systems, and portable health and fitness equipment and smart accessories.
Features and USP: Designed to significantly reduce current consumption, the EFM32 Gecko and Tiny Gecko microcontrollers operate at 160µA per MHz in active mode, executing code from Flash; 900nA in deep sleep mode and 20nA in shut off mode. The EFM32G232, EFM32G842, EFM32TG232 and EFM32TG842, which are available in various configurations of Flash memory ranging from 8 to 128 KB and from 2 KB to 16 KB of RAM, offer the same energy saving Gecko technology as other package options in the EFM32 MCU range. In application benchmark tests, this product’s low current performance, combined with a wake-up time of 2µs has enabled the EFM32 microcontrollers to extend battery cell life by a factor of at least four.
