SILICON LABS EFM32TG11B140F64GQ48-A

The EFM32 Tiny Gecko Series 1 MCUs are energy-efficient microcontrollers with new connectivity interfaces and rich analog capabilities. The EFM32TG11 is equipped with a powerful and efficient 32-bit ARM Cortex - M0+ and offers enhanced security through a unique cryptographic hardware engine that supports AES, ECC, SHA, and a True Random Number Generator (TRNG). New features include a CAN bus controller, highly reliable capacitive sensing, and LESENSE/PCNT smart electricity meter enhancements. These features, combined with the ultra-low current active mode and the ability to wake up quickly from energy-saving modes, make the EFM32TG11 microcontroller suitable for any battery-powered applications as well as other systems with high-performance and low-power requirements.
