EFM32 Giant Gecko Starter Kit

EFM32GG-STK3700 Giant Gecko Starter Kit

Silicon Labs

The EFM32GG Giant Gecko is the ideal choice for demanding 8-, 16-, and 32-bit energy sensitive applications. The devices are developed to minimize the product of power and time over all phases of MCU operation.

Product Description

The starter kit supports the most memory rich devices within the 240-strong ARM Cortex-M EFM32 Gecko family. Including full SEGGER J-Link support, the kits are the first products to feature the enhanced version of Energy Micro’s real-time current probe, the energyAware profiler. This Advanced Energy Monitoring system (AEM) ensures that current data can be viewed with improved accuracy and 100 times faster than earlier versions, eliminating the need to connect external instruments to find current drains.

The EFM32-GGSTK3700 is based on the EFM32GG990F1024, the industry’s only energy-friendly MCU with 1MB on-chip Flash and 128KB RAM memory. The generous range of memory options gives designers the opportunity to implement complex embedded designs while maintaining best in class energy efficiency. Giant Gecko MCU can directly control a TFT display and feature a USB driver that supports the Host, Device and On-the-Go (OTG) protocols.

The new EFM32 Giant Gecko STKs are additionally equipped with light, metal and touch sensors. These enable designers to investigate the Gecko´s unique LESENSE Low Energy Sensor interface, which allows passive sensing of 16 sensors without host CPU intervention. The hardware feature set is completed by a USB plug, 32MB on-board NAND Flash, LCD and a variety of LEDs and push-buttons.
