Applications // Microcontrollers (MCUs) for Battery Operated Embedded Devices

Microcontrollers (MCUs) for Battery Operated Embedded Devices

Design without compromise using low power EFM32™ ARM® Cortex®-M based 32-bit MCUs and EFM8™ 8051-based 8-bit MCUs. Integrate peripherals, include rich displays and perform complex computations while meeting the power budget of your system by using energy-friendly MCUs from Silicon Labs.

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.



EFM32GG11 Starter Kit

The SLSTK3701A starter kit contains sensors and peripherals demonstrating some of the MCU's many capabilities and can serve as a starting point for application development.

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.
