Energy Micro
family. The 32-bit EFM32 MCUs are packed with peripherals built for low energy operation and can increase
battery life 4 times compared to other low power 8-, 16-, and 32-bit microcontrollers.
10 factors why EFM32 MCUs are the world's most energy friendly microcontrollers
4 times longer battery life with 32-bit EFM32 Gecko microcontrollers
Energy Modes increase battery and application lifetime
Embedded designers get the flexibility to tune their systems energy behavior and complexity with highly efficient
Energy Modes and only 2 µs wake-up to Active Mode. Peripherals can be enabled to communicate with each
other (PRS) and perform advanced operations without any CPU intervention in the ultra low energy modes.
