EFM32 Giant Gecko 32-Bit Microcontrollers

Silicon Labs EFM32 Giant Gecko 32-Bit Microcontrollers are part of the world's most energy-friendly microcontrollers and will provide Flash memory configurations up to 1024KB with the added option of embedded USB connectivity, direct-drive TFT, EBI and CPU speeds up to 48 MHz. All Giant MCUs include the same autonomous, low-energy peripherals found in the Gecko family, like AES encryption, Pulse Counter, Low Energy UARTs in addition to the Low Energy Sensor interface LESENSE and on-chip Operational Amplifiers. These devices target energy-sensitive applications with high memory requirements and connectivity requirements.
