Energy-friendly MCUs for smart devices

Mouser now stocks the EFM32Giant Gecko 12 MCU family from Silicon Labs. Created to offer advanced features and security during ultra-low-power performance, the device offers low-energy peripherals to deliver autonomous performance while sleeping. The GG12 microcontrollers are ideal for a wide range of applications requiring advanced processing during deep sleep, including IoT devices, smart meters, sensors, home security, industrial automation, and health and fitness wearables. The EFM32 Giant Gecko 12 family provides many of the features of the Giant Gecko 11 microcontrollers in a smaller package, and adds a unique PDM sensor interface to support PDM microphones and delta-sigma sensors. The microcontrollers boast a 32-bit Arm Cortex-M4 processor running at 72MHz with up to 1Mbyte of on-chip flash and 192Kbytes of RAM. Connecting this power with rich analog features, the devices produce an advanced user experience previously achievable only on high-power-consumption microcontrollers. The EFM32 Giant Gecko 12 family is supported by the Thunderboard GG12 kit for prototyping and evaluation. The kit comprises an integrated Segger J-Link debugger, tri-colour LEDs, two PDM microphones, and breakout ports, and push buttons. The board also comprises an out-of-box demo for the microcontroller’s PDM sensor interface, making it an excellent choice for the development of high-quality, low-power audio input applications.
