Silicon Labs EFM32TG110F16-QFN24 - Ultra-Low-Power ARM Cortex-M3 Microcontroller

The EFM32TG110F16-QFN24 is a high-performance 32-bit ARM® Cortex®-M3 microcontroller from Silicon Labs' renowned Tiny Gecko series, specifically engineered for ultra-low-power embedded applications. Operating at 32MHz with 16KB Flash memory and 4KB RAM, this MCU delivers exceptional energy efficiency perfect for battery-powered IoT devices, wearables, and industrial sensors.

Featuring 17 I/O pins in a compact 24-QFN (5x5mm) surface-mount package, the EFM32TG110F16 integrates essential peripherals including I2C, SPI, UART/USART, and SmartCard interfaces. Advanced analog capabilities include 2x12-bit ADC and 1x12-bit DAC converters, while built-in DMA, PWM, and watchdog timer enhance system reliability and performance.

With an ultra-wide voltage range (1.85V-3.8V) and industrial temperature rating (-40°C to 85°C), this microcontroller ensures robust performance across demanding environments. RoHS compliant and supplied in tape & reel packaging, it's ideal for production-scale deployment in energy-harvesting systems, smart meters, portable medical devices, and wireless sensor networks.

Advanced Power Management & Energy Efficiency

The EFM32TG110F16 excels in ultra-low-power operation with multiple energy modes optimized for battery-powered applications. The ARM Cortex-M3 core delivers 1.25 CoreMark/MHz efficiency while consuming as low as 180 µA/MHz in active mode and less than 1 µA in deep sleep mode. Energy Mode 0 (EM0) provides full CPU and peripheral operation, while EM1-EM4 progressively reduce power consumption by selectively disabling peripherals and clocks. The integrated Energy Management Unit (EMU) enables intelligent power mode transitions, extending battery life in coin-cell and energy-harvesting applications by up to 10x compared to traditional microcontrollers.

Rich Peripheral Integration & Connectivity

This microcontroller features a comprehensive peripheral set designed for industrial and IoT applications. The dual 12-bit 1 Msps ADC channels support differential and single-ended measurements with programmable gain amplifier (PGA), enabling precision sensor interfacing for temperature, pressure, and analog signal monitoring. The 12-bit DAC provides accurate analog output for control systems and audio applications. Communication interfaces include two USART modules supporting UART, SPI, and SmartCard protocols, plus I2C for multi-device bus communication. The Low Energy UART (LEUART) operates independently in sleep modes, enabling asynchronous data reception while maintaining ultra-low power consumption. Built-in DMA controller offloads CPU tasks, reducing active power consumption during data transfers.
