EFM32TG108F4-QFN24 Übersicht
A microcontroller is a programmable integrated circuit that combines a processor core, memory, and peripherals such as timers, communication interfaces, and I/O ports. The EFM32 Tiny Gecko MCU combines an ARM Cortex-M3 processor with energy-saving modes and low-power techniques. This places it within the embedded MCU hierarchy alongside 8-bit and 32-bit microcontrollers, supporting control, sensing, communications, and small system automation.
The device provides 4 KB Flash for firmware storage and 2 KB RAM for working memory. Its 17 digital I/O pins enable external sensors, buttons, indicators, and control signals, while two 16-bit timers support periodic events, timing, and basic control functions. The 32 MHz Cortex-M3 core provides substantially more processing capability than typical low-end 8-bit designs while retaining a compact footprint.
The EFM32TG108F4-QFN24 operates from a 1.85 V to 3.8 V supply according to the available product data. Its operating temperature is reported as -40°C to 85°C. The 24-QFN package is suitable for space-constrained PCB layouts and supports surface-mount assembly. The product data does not establish a public detailed pinout for every signal, so pin names and functions are marked as data needed rather than inferred.
Typical applications include low-power sensor nodes, compact industrial controllers, embedded monitoring equipment, battery-powered instruments, and embedded communication modules. For designs requiring more memory, peripherals, or package pins, a larger MCU family member may be preferable. Before finalizing a footprint, verify the exact pin assignment, exposed-pad requirements, and decoupling recommendations against the manufacturer datasheet.
This product page combines manufacturer specifications, distributor availability, pricing references, cross-reference results, and practical selection guidance to help engineers evaluate the EFM32TG108F4-QFN24 for embedded designs.

Typische Anwendungen
EFM32TG108F4-QFN24 ist geeignet für 6 Anwendungs: Battery-Powered Sensor Node, Industrial Environmental Monitor, Embedded Measurement Instrument, Low-Power Remote Control, Compact Data-Acquisition Controller, Smart IoT Sensor Gateway.
Battery-Powered Sensor Node
The EFM32TG108F4-QFN24 fits compact battery-powered sensor nodes that need a 32-bit Cortex-M3 core without the memory footprint of a larger MCU. Its 4 KB Flash and 2 KB RAM are suitable for small control loops, sensor sampling, state machines, and low-power duty cycling. Silicon Labs highlights energy-saving modes and fast wake-up behavior, helping the design remain responsive while reducing time spent active. The 17 digital I/O pins can support a sensor, status indicator, and control inputs. Because sleep current, wake-up latency, and exact pin functions were not included in the supplied data, validate them from the manufacturer datasheet before calculating battery life.
Empfohlen
Industrial Environmental Monitor
EFM32TG108F4-QFN24 is appropriate for compact industrial monitoring equipment where a controller must read sensors, apply thresholds, record events, and control indicators. Its 32 MHz ARM Cortex-M3 core provides a 32-bit processing platform, while two 16-bit timers can support periodic sampling, debounce timing, or motor and actuator timing. The 24-QFN 5x5 mm package limits board footprint for distributed monitoring nodes. The 1.85 V to 3.8 V operating range allows integration with low-voltage sensor and regulated power systems. Confirm industrial temperature requirements, EMC layout, and exact peripheral assignments against the device documentation before production.
Empfohlen
Embedded Measurement Instrument
The EFM32TG108F4-QFN24 can serve as the control MCU in a small embedded measurement instrument when the application prioritizes low power and a compact footprint over large onboard memory. The Cortex-M3 core can execute calibration logic, measurement sequencing, and user-interface updates, while the two 16-bit timers help organize sampling intervals. Its 17 digital I/O pins provide access to switches, status LEDs, and control signals. The 24-QFN package also supports dense board layouts. The supplied data does not include ADC specifications, analog peripherals, or detailed timing parameters, so analog accuracy and signal-chain suitability must be verified separately.
Empfohlen
Low-Power Remote Control
EFM32TG108F4-QFN24 is suitable for handheld or remote-control products that wake periodically, decode user input, update a display or indicator, and return to a low-energy state. The Cortex-M3 core offers more general-purpose processing than an 8-bit controller, while the 4 KB Flash and 2 KB RAM constrain firmware size and require careful code organization. Silicon Labs describes fast wake-up and energy-saving modes as core benefits of the Tiny Gecko platform. The MCU can manage buttons, LEDs, and low-power interface signals through its 17 digital I/O pins. Wireless or display companion requirements are not supplied and must be selected according to the product architecture.
Empfohlen
Compact Data-Acquisition Controller
The EFM32TG108F4-QFN24 can coordinate a small data-acquisition system when the system uses external sensors or converters and the MCU primarily handles sequencing, configuration, and data movement. Its two 16-bit timers support periodic acquisition and timing functions, while the 32-bit core can manage control software and buffering within the available 2 KB RAM. The 24-QFN 5x5 mm package helps reduce board size in portable or embedded instruments. ADC resolution, sample-rate limits, serial-interface resources, and DMA behavior were not included in the supplied verified data, so engineers must confirm them before selecting this MCU for precision acquisition.
Empfohlen
Smart IoT Sensor Gateway
EFM32TG108F4-QFN24 can be used in a small IoT sensor gateway or edge node that aggregates local sensor inputs and controls low-power communications. Its 32 MHz Cortex-M3 core supports protocol handling and control logic, while 17 digital I/O pins can connect discrete sensors, interrupt lines, and status indicators. The Tiny Gecko low-energy positioning is useful in systems that spend substantial time between activity periods. The MCU has only 4 KB Flash and 2 KB RAM, so gateway designs should use compact firmware and offload memory-intensive networking functions to a companion module. The supplied data does not verify specific Ethernet, wireless, or security peripherals.

Wichtigste Unterscheidungsmerkmale
- Compact 32-bit control platform (vs. EFM32TG108F4-D-QFN24)
- Low-power family positioning (vs. EFM32TG108F32-D-QFN24)
- Documented supply-voltage range (vs. EFM32TG108F32-D-QFN24)
Designhinweise
Design the supply for the verified 1.85 V to 3.8 V operating range and reserve local decoupling close to the device power pins. The supplied manufacturer search results mention an on-chip regulator DECOUPLE pin and an errata concerning its output, so verify the recommended external connection and bypass requirements in the current datasheet and errata before layout release. Do not assume that the DECOUPLE behavior of an earlier revision applies unchanged.
Use the exact 24-QFN 5x5 mm land pattern and thermal-pad geometry from the manufacturer package drawing. Confirm whether the exposed pad is electrically connected, required for thermal relief, or specified as no-connect before assigning its net. Because the supplied data confirms the package size but does not provide the complete pinout or exposed-pad drawing, footprint and stencil decisions must be checked against the official mechanical documentation.
Do not treat a matching QFN package name as proof of drop-in compatibility. For EFM32TG108F4-D-QFN24 and EFM32TG108F32-D-QFN24, verify signal-by-signal pinout, power requirements, reset behavior, memory, peripheral mapping, and startup timing. The supplied search results establish the package family and some broad specifications, but they do not provide enough evidence to approve a production substitution without manufacturer documentation.
Keep sensitive signal routing short and place support components according to the datasheet reference layout. The MCU is intended for low-energy operation, so avoid long leakage paths around exposed pads, sensitive reset circuitry, and power pins when the package construction permits. For sensor or communication interfaces, separate fast-switching or high-current paths from analog and measurement traces to reduce coupling and improve repeatability.
Compliance-Informationen
The supplied verified data does not provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than inferred.
