SILICON LABS EFM32TG11B520F128GM32-BR

The EFM32 Tiny Gecko Series 1 MCUs are energy-friendly microcontrollers, featuring new connectivity interfaces and rich analog features. EFM32TG11 includes a powerful and efficient 32-bit ARM Cortex-M0+ and provides robust security via a unique cryptographic hardware engine supporting AES, ECC, SHA, and True Random Number Generator (TRNG). New features include a CAN bus controller, highly robust capacitive sensing, 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 EFM32TG11 microcontrollers well suited for any battery-powered application, as well as other systems requiring high performance and low-energy consumption.
