Overview

The EFM32TG11B120F128GM64-B is a 32-bit ARM Cortex-M0+ microcontroller from Silicon Labs Tiny Gecko 1 series, designed for energy-sensitive applications. Operating at up to 48MHz, it integrates 128KB of flash and 32KB of RAM with a rich set of peripherals including CAN bus and an integrated LCD controller. Its ultra-low power architecture consumes as little as 32 uA/MHz in active mode and 0.5 uA in standby, making it ideal for battery-operated devices.

Why Choose This Part

This MCU offers an exceptional balance of low-power performance and peripheral integration, featuring a DC-DC buck converter and a Peripheral Reflex System (PRS) that allows autonomous communication between peripherals without CPU intervention. The inclusion of hardware CAN support and a dedicated security unit on a Cortex-M0+ core provides advanced functionality typically reserved for higher-power processors.

Applications

Industrial Sensor Nodes
Utilizes the integrated CAN bus and ultra-low power analog peripherals for distributed sensing in industrial environments.
Battery-Powered Wearables
Leverages the integrated LCD controller and low sleep currents (1.37 uA) to extend battery life in human-interface devices.
Smart Utility Meters
The hardware cryptographic engine and Security Management Unit (SMU) provide the necessary protection for utility data transmission.
Capacitive Touch Interfaces
Integrated Capacitive Sense (CSEN) peripheral allows for low-power touch buttons and sliders without external controllers.
