SILICON LABS EFM32GG12B430F512GL112-A

EFM32 Giant Gecko Series 1 MCUs feature new connectivity interfaces and user interface features. EFM32GG12 includes a powerful 32-bit ARM Cortex - M4 and provides robust security via a unique cryptographic hardware engine supporting AES, ECC, SHA, and True Random Number Generator (TRNG). New features include an SD/MMC/SDIO controller, Octal/Quad - SPI memory controller, CAN bus controller, PDM interface, highly robust capacitive sensing, enhanced alpha blending graphics engine, and LESENSE/PCNT enhancements for smart energy meters. These features, combined with ultra - low current active mode and short wake - up time from energy - saving modes, make EFM32GG12 microcontrollers well suited for any battery - powered application, as well as other systems requiring high performance and low - energy consumption.
