Silicon Labs provides the largest portfolio of energy friendly 32-bit microcontroller (MCU) products for ultra-low power applications.
The EFM32 Gecko microcontroller family includes the energy-efficient devices based on ARM Cortex-M4 with Floating Point Unit (FPU), Cortex-M3 and Cortex-M0+ processors. The Precision32 32-bit microcontroller family provides a highly integrated and flexible architecture, a rich peripheral set and ultra-low power consumption.
It 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.
The family includes 60 devices based on the ARM© Cortex®-M4 core, which provides a full DSP instruction set and includes a hardware FPU for faster computation performance. Wonder Gecko MCUs feature up to 256 kB of flash memory, 32 kB of RAM and CPU speeds up to 48 MHz.
The MCUs incorporate highly differentiated Gecko technology to minimise energy consumption, including a flexible range of standby and sleep modes, intelligent peripherals that allow designers to implement many functions without CPU wake-up and ultra-low standby current. With the lowest active and standby power consumption, the Wonder Gecko is the world's most energy-friendly Cortex-M4 MCU.
