Energy Micro is a fabless semiconductor company focused on providing energy friendly microcontrollers. The company's target market sectors include energy metering, home and building automation, and alarm and security industries where battery replacements aren't possible for reasons of access or cost.
Energy Micro's EFM32 Gecko microcontroller family is based on the ARM Cortex-M3 microcontroller architecture. The company introduced its EFM32 Tiny Gecko product family this year. The EFM32 microcontrollers feature a set of low energy and autonomous peripherals suitable for low power and battery operated applications.
The EFM32 consumes less than 180µA per MHz while executing real life code from Flash. Its standby current consumption is typically 900nA while running real time clock, power-on reset, brown-out detector, and full RAM and CPU retention. Its deepest sleep mode supports a less than 20nA current draw. The microcontroller features a start-up time of less than 2µs.
