Référence : EFM32TG110F4-QFN24T ✓ ActifEFM32TG110F4-QFN24T Présentation
A microcontroller is a programmable semiconductor that integrates a processor core, memory, peripherals, and I/O into one compact device. The EFM32TG110 belongs to the Tiny Gecko family of 32-bit ARM Cortex-M3 microcontrollers, a branch of embedded processors designed for low-power control, sensing, communications, and user-interface functions. Its 24-pin QFN package also supports compact, high-density PCB layouts.
Key device features include a 32 MHz Cortex-M3 core, 4 KB of Flash program memory, 2 KB of SRAM, 17 digital I/O pins, two 16-bit timers, three operational amplifiers, and AES hardware support. The operating supply range of 1.85 V to 3.8 V suits both 2.5 V and 3.3 V system rails. These resources are intended for modest control tasks where energy efficiency, rapid startup, and peripheral integration matter more than large memory capacity.
The Cortex-M3 processor uses the ARM Thumb instruction set and provides a conventional embedded software ecosystem. Hardware peripherals reduce processor workload for timing, analog measurements, communications, and data-security functions. The integrated operational amplifiers can support analog signal conditioning, while AES support provides a hardware path for encrypted data handling. Firmware development requires suitable ARM debugging tools, a driver library, and a board configured for the device power, clock, reset, and programming interface.
Typical uses include battery-powered sensors, compact industrial monitoring nodes, building and access controls, portable measurement instruments, low-energy IoT endpoints, and small motor or actuator controllers. The 4 KB Flash and 2 KB RAM favor focused applications with modest code and working-data requirements, while the 17 I/O pins allow several sensors, indicators, and external interfaces to share one controller.
Designers should verify every exposed-pin function, programming connection, and decoupling requirement against the manufacturer pin description and reference schematic. Place the exposed pad and ground-plane connection according to the package drawing, provide local supply bypassing, and confirm that the firmware linker configuration matches the 4 KB Flash and 2 KB RAM partition.
This product page consolidates the core device specifications, practical design considerations, package information, and documented cross-reference candidates into an engineering-focused selection resource. It also distinguishes the exact ordered device from related family members whose memory, core, package suffix, or ordering configuration differs.

Applications typiques
EFM32TG110F4-QFN24T convient pour 6 applications: Battery-Powered IoT Sensor Nodes, Industrial Condition Monitoring, Building Access and Security Controls, Portable Measurement Instruments, Smart Lighting and Relay Control, Low-Power Data Acquisition Front End.
Battery-Powered IoT Sensor Nodes
The EFM32TG110F4-QFN24T fits compact IoT sensor nodes that wake periodically, acquire a measurement, transmit data, and return to a low-energy state. Its low-power platform, fast wake-up behavior, 32 MHz Cortex-M3 core, and 2 KB of RAM support responsive control without requiring a high-power processor. The 4 KB Flash limit means firmware should be tightly scoped, while AES hardware support can reduce software overhead for encrypted data. For battery-life calculations, include radio activity, sensor warm-up time, and wake duration alongside the microcontroller sleep current.
Recommandé
Industrial Condition Monitoring
The EFM32TG110F4-QFN24T is suitable for industrial condition-monitoring modules that combine a small sensor interface with local status indication and communications. Its 17 digital I/O pins can accommodate switches, discrete sensors, and logic-level peripheral signals, while three operational amplifiers support conditioning stages close to the sensing element. The 2.5 V or 3.3 V operating range helps integrate with low-voltage industrial electronics. Design the analog path around the integrated amplifiers' electrical limits, provide clean references, and isolate noisy motor or relay wiring from sensitive measurement nodes.
Recommandé
Building Access and Security Controls
The EFM32TG110F4-QFN24T can manage compact access-control peripherals such as door contacts, lock drivers, status LEDs, request-to-exit inputs, and a local keypad. Its 17 digital I/O pins and two 16-bit timers provide enough resources for deterministic monitoring and timing functions, while AES hardware support is useful for secure credential or communication handling. Keep the firmware within the 4 KB Flash budget and use a hardware random source where the security design requires one. Validate lock-driver isolation so switching transients do not disturb the controller or its supply rail.
Recommandé
Portable Measurement Instruments
The EFM32TG110F4-QFN24T is appropriate for compact handheld or wearable measurement devices requiring low standby consumption and mixed analog and digital control. Three integrated operational amplifiers can handle sensor amplification, filtering, or buffer stages, while the 32 MHz Cortex-M3 core performs acquisition control and local calculations. The 24-QFN footprint preserves board area, and the 1.85 V to 3.8 V range supports low-voltage designs. Establish the analog settling time, sensor bandwidth, and calibration strategy before fixing the signal chain, and reserve sufficient Flash for calibration tables and production configuration.
Recommandé
Smart Lighting and Relay Control
The EFM32TG110F4-QFN24T can control low-power lighting, indicators, relays, or small actuator boards when the design stays within its 17 available digital I/O lines. Two 16-bit timers support timing, debouncing, pulse generation, or scheduled events, while the low-power platform permits sleep between infrequent commands. External drivers are necessary for loads above the controller's I/O capability. Keep inductive loads physically separated from analog and radio areas, use appropriate protection components, and place bulk and bypass capacitance near the supply pins.
Recommandé
Low-Power Data Acquisition Front End
The EFM32TG110F4-QFN24T is well suited to a distributed data-acquisition front end that combines sensor conditioning, digital triggering, and a local serial interface. Its three operational amplifiers reduce the need for external analog stages, and the 32 MHz core provides enough control bandwidth for sampling, filtering, and packet preparation. The 4 KB Flash and 2 KB RAM capacities are best suited to targeted acquisition tasks rather than local data buffering. Define calibration intervals, input common-mode limits, and trigger latency in firmware while keeping high-speed or high-current sensing circuits outside the QFN device.

Notes de conception
Route the 24-QFN device with the exposed pad connected according to the manufacturer package drawing, and provide both bulk capacitance and high-frequency bypass close to the supply pins. Keep analog inputs associated with the three operational amplifiers away from switching nodes and digital return currents. The 5 x 5 mm land pattern should be checked against the current package drawing before releasing artwork.
Design the supply rail for the documented 1.85 V to 3.8 V operating range and include margin for startup transients, I/O loading, and peripheral current. Use a stable source for the internal core rail and confirm the external decoupling values specified by the manufacturer. If the board combines radio, motor, or relay loads, separate their bulk storage from the microcontroller supply and prevent those loads from pulling the rail outside its operating limits.
Do not assume that identical package dimensions establish drop-in compatibility. A replacement must preserve power and ground assignments, reset and debug signals, analog-pin limits, peripheral mapping, exposed-pad requirements, and firmware-compatible device identity. EFM32TG110F4-QFN24 is the closest documented candidate, but its suffix, packing, temperature grade, and manufacturer ordering status should be confirmed before substitution.
Treat the 4 KB Flash and 2 KB RAM as hard design limits. Configure the linker to match the exact device, reserve adequate stack space for interrupt and library calls, and monitor code growth before production. For encrypted products, use the integrated AES peripheral only within a hardware-backed key-management and boot-security design; the presence of AES hardware alone does not establish complete system security.
Give analog signals a continuous return path and keep them away from high-current edges. If the integrated operational amplifiers drive or sense near ADC and radio circuitry, verify input range, output swing, stability, noise, and bias behavior against the electrical characteristics. Add series resistance only where it does not disrupt sensor bandwidth, and use a solid ground plane without splitting return paths beneath the analog section.
