The EFM32 Gecko from Energy Micro is an energy friendly 32-bit microcontroller for use in ultra low power applications; energy, gas, water and smart energy metering, building automation, security and medical equipment. Such applications need to operate for as many years as is possible without external power and operator intervention. Benchmarking against today's 'top 10' low power microcontroller devices, the EFM32 Gecko Microcontroller has been proven capable of consuming a quarter of the energy required by 8-bit, 16-bit or 32-bit alternatives. This can equate to extending the lifetime of a typical 3V coin cell battery by at least 300% or 7 years. Energy Micro has built the EFM32 Gecko microcontroller around the 32-bit ARM Cortex-M4 with FPU, Cortex-M3 and Cortex-M0+ processor core. In summary the microcontroller is characterized by ultra low active power consumption, reduced processing time, very fast wake-up time and ultra-low standby current.
