Product Description
Silicon Labs’ EFM32 Zero Gecko is the newest member of the Gecko family of ultra-low power and energy-friendly 32-bit microcontrollers.
The Zero Gecko combines the powerful ARM Cortex-M0+ core, innovative low-energy techniques, short wake-up time from energy saving modes and a wide selection of peripherals, making it ideal for battery operated applications and other systems requiring high performance and low energy consumption.
Silicon Labs also supplies the EFM32ZG-STK3200 starter board, which provides an excellent tool to get familiar with the EFM32.
It is supported by Simplicity Studio and contains sensors and peripherals that demonstrate some of the MCU's many capabilities and can serve as a starting point for application development. The EFM32ZG-STK3200 features an on-board SEGGER J-Link debugger and an Advanced Energy Monitoring system, allowing you to program, debug and perform real-time current profiling of your application without using external tools.
Power sources include USB and a CR2032 battery. The starter kit also features 2 user buttons, 2 user LEDs, 2 capacitive touch pads, an ultra-low power 128x128 pixel Memory-LCD and crystals for LFXO and HFXO: 32.768 kHz and 24.000 MHz.
