EFM32 32-bit MCUs for Battery Operated Embedded Devices
Silicon Labs' EFM32 32-bit microcontroller (MCU) family is the world's most energy-friendly microcontroller and is especially suited for use in low-power and energy-sensitive applications, including energy, water, and gas metering, building automation, alarm and security and portable medical/fitness equipment. Since battery replacement is often not possible for reasons of access and cost, such applications need to operate for as long as possible without external power or operator intervention.

EFM8 8-bit MCUs for Battery Operated Embedded Devices
Silicon Labs designed the EFM8 8-bit microcontroller (MCU) family from the ground up to be the most power-efficient MCUs in the industry. The combination of the low active mode current consumption when the application is running and the industry’s lowest current consumption in sleep modes saves power in real world embedded system. This combination of features makes these devices ideal for many battery-powered applications.
