EFM32TG108F16-QFN24 - 32MHz 16KB MCU | Silicon Labs
Référence : EFM32TG108F16-QFN24 ✓ ActifEFM32TG108F16-QFN24 Présentation
A microcontroller is a semiconductor device that integrates a processor core, program memory, working memory, and peripherals into one compact package. The EFM32TG108 belongs to the Tiny Gecko family, a low-power 32-bit microcontroller line built around the ARM Cortex-M3 architecture. Its position in the hierarchy is MCU, embedded microcontroller, embedded processor, and semiconductor. The architecture combines a 32 MHz maximum clock with energy-saving modes and short wake-up behavior intended for systems that spend substantial time in low-power states.
The EFM32TG108F16-QFN24 provides 16 KB (16K x 8) of Flash for firmware and 32-bit processing through the ARM Cortex-M3 core. Its verified 24-QFN package measures 5 x 5 mm and is suitable for compact, surface-mounted designs. The operating range of 1.85 V to 3.8 V supports 2.5 V and 3.3 V system architectures, although individual external components and board-level voltage tolerances must still be checked. The supplied distributor listing identifies the MCU as an ARM Cortex-M3 Tiny Gecko part rated at 32 MHz.
The principal technical benefit is efficient 32-bit processing in a small, low-power package. A 32 MHz clock provides useful computation headroom for protocol handling, control loops, signal acquisition, and system management without requiring a larger processor package. Low-power operation is particularly relevant when average energy per task, rather than peak processing speed, determines battery life. The available evidence does not specify the target device's RAM capacity, GPIO count, timer configuration, analog performance, or exact power-consumption figures, so those parameters should be confirmed in the manufacturer datasheet before final design release.
Typical uses include wearable accessories, compact sensor nodes, industrial monitoring modules, energy meters, portable measurement products, and low-power embedded control boards. In each case, the device can act as the central controller, executing application firmware while using sleep states between infrequent events. Designers should size the decoupling network around the device-specific requirements in the EFM32TG108 datasheet and preserve adequate routing clearance for high-speed signals and radio-adjacent circuitry.
The principal design consideration is avoiding unverified assumptions about the peripheral complement. Firmware drivers, pin multiplexing, programming interfaces, brownout behavior, and exact memory availability must be checked against the correct datasheet revision for the selected orderable MPN. This page combines the verified distributor specifications, package data, source links, and same-family replacement candidates into a practical sourcing and design reference.
This product page additionally distinguishes verified characteristics from missing parameters, summarizes the strongest documented use cases, and identifies same-family QFN-24 alternatives without presenting uncertain cross-family parts as guaranteed drop-in replacements.

Applications typiques
EFM32TG108F16-QFN24 convient pour 6 applications: Battery-Powered Sensor Nodes, Industrial Monitoring and Control, Wearable and Portable Devices, Energy Metering, Portable Measurement Instruments, Connected IoT Control Modules.
Battery-Powered Sensor Nodes
The EFM32TG108F16-QFN24 fits compact battery-powered sensor nodes because its 32 MHz ARM Cortex-M3 core provides sufficient control capability while the Tiny Gecko architecture is designed around low-energy techniques, energy-saving modes, and short wake-up times. Its 1.85 V to 3.8 V supply range fits low-voltage sensor rails, while the 5 x 5 mm QFN package preserves board area. The device can wake to acquire a measurement, perform local filtering, and return to a low-power state. Exact active and sleep current must be taken from the manufacturer datasheet because the supplied records do not quantify them. Firmware size should also be checked against the 16 KB Flash limit before adding protocol stacks or update buffers.
Recommandé
Industrial Monitoring and Control
The EFM32TG108F16-QFN24 can serve as the embedded controller in an industrial monitoring module because its 32-bit Cortex-M3 core runs up to 32 MHz and its 16 KB Flash accommodates embedded control and communication firmware. The 1.85 V to 3.8 V operating range supports 2.5 V and 3.3 V industrial electronics, while the compact 24-QFN package reduces footprint in densely populated control cards. A typical design would use the MCU for state-machine execution, sensor conditioning commands, diagnostics, and local data buffering. Engineers should confirm the required GPIO, timers, ADC, and serial interfaces against the exact datasheet because those peripheral details were not quantified in the supplied web results.
Recommandé
Wearable and Portable Devices
The EFM32TG108F16-QFN24 is appropriate for wearable and portable products where board area and energy use are constrained. Its 24-QFN package occupies only 5 x 5 mm, and the 32 MHz Cortex-M3 core provides enough performance for user-interface control, gesture logic, or connected-device protocol handling. The 1.85 V to 3.8 V operating range allows integration with low-energy 2.5 V or 3.3 V power trees, and the Tiny Gecko family's short wake-up behavior can support responsive event-driven operation. The 16 KB Flash constraint should be evaluated against bootloader, application, and update requirements. RAM, GPIO, and exact sleep-current data must be verified before a wearable design is released.
Recommandé
Energy Metering
The EFM32TG108F16-QFN24 can support energy-metering front ends where a dedicated MCU must combine measurement control, calibration handling, and data processing in a small package. Its 32 MHz ARM Cortex-M3 architecture provides more computation headroom than an 8-bit controller, while the Tiny Gecko family's low-power modes suit meters that remain active for long periods between measurement updates. The 24-QFN footprint supports compact meter boards, and the 1.85 V to 3.8 V supply range permits operation from a regulated low-voltage source. Actual analog connectivity and timer availability are not specified in the supplied records, so the engineer must confirm the required metering peripherals and calibration-memory budget in the EFM32TG108 datasheet.
Recommandé
Portable Measurement Instruments
The EFM32TG108F16-QFN24 fits portable measurement instruments that need deterministic embedded control without the footprint of a larger microcontroller. At up to 32 MHz, the Cortex-M3 core can coordinate acquisition sequencing, control peripheral devices, and execute local calculations, while the Tiny Gecko low-power platform benefits instruments that operate for long periods between user interactions. The 5 x 5 mm QFN package leaves room for analog and interface circuitry on a densely populated board. The 16 KB Flash limit is suitable for focused firmware but may be restrictive for graphical interfaces or extensive protocol libraries. Verify ADC, timer, serial-interface, memory, and pin requirements in the manufacturer documentation before selecting it for a new instrument architecture.
Recommandé
Connected IoT Control Modules
The EFM32TG108F16-QFN24 can function as the low-power controller in a connected IoT module that performs local logic, sensor handling, and communication-stack support. The 32 MHz ARM Cortex-M3 core provides sufficient throughput for protocol state machines and application logic, while the 1.85 V to 3.8 V supply range supports common low-voltage rails. Its 24-QFN package is useful when the radio, power system, and sensors already constrain PCB area. The Tiny Gecko family's energy-saving modes and short wake-up times are valuable for intermittent wireless traffic. Because Flash is limited to 16 KB, stacks with substantial code and memory requirements may be better served by the 32 KB F32 variant. Exact RAM and peripheral availability require datasheet confirmation.

Principaux différenciateurs
- Balances 32-bit processing with a 16 KB memory footprint (vs EFM32TG108F8-QFN24)
- Uses less onboard code storage than the higher-capacity family option (vs EFM32TG108F32-QQN24)
- Provides a documented low-voltage operating range in a compact QFN package (vs EFM32TG108F16-D-QFN24)
Notes de conception
Design the EFM32TG108F16-QFN24 power tree around the verified 1.85 V to 3.8 V device range and the requirements of the selected board voltage, commonly 2.5 V or 3.3 V. Place the manufacturer's required input and output capacitors close to the supply pins, verify their voltage and DC-bias characteristics, and confirm startup behavior against the selected grade. Do not infer quiescent or sleep current from the 1.85 V to 3.8 V specification; obtain those values from the exact datasheet revision and validate them on the final board.
Use the manufacturer QFN-24 land pattern and match it to the exposed-pad, thermal, and solder-mask requirements shown in the EFM32TG108 package drawing. Although the package is only 5 x 5 mm, pin escape and exposed-pad soldering can dominate assembly yield. Check paste volume and the reflow profile for the selected package, preserve access for inspection, and avoid placing tall components where they can interfere with the QFN body or thermal pad.
Do not assume that every EFM32TG108 memory suffix is interchangeable. The F16 target has 16 KB of Flash, while the F8 and F4 family variants provide 50% and 75% less storage, respectively; the F32 variant doubles it. A replacement can therefore fail even when its package and CPU match if bootloader or application code exceeds the new device's Flash. Rebuild with the replacement's official headers, linker configuration, and memory map, then verify programming and wake-up behavior.
Keep sensitive analog or high-speed signal paths away from the MCU's supply-return and switching-current loops, while routing decoupling current to the relevant pins through short, low-loop-area paths. Clock, debug-programming, and communication nets require continuity and impedance decisions appropriate to their edge rates. The supplied data does not identify the full pin map or board-level layout requirements, so use the datasheet pin table and recommended layout schematic as the controlling references.
Informations de conformité
The supplied manufacturer and distributor records do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. These fields remain unknown rather than being inferred from the product family or package.
