EFM32TG110F8-QFN24 Übersicht
A microcontroller is a programmable system-on-chip that integrates a CPU, nonvolatile program memory, volatile data memory, peripherals, and I/O into one package. The EFM32 Tiny Gecko family belongs to the hierarchy of embedded processors, microcontrollers, integrated circuits, and semiconductors. It is designed to execute firmware while controlling sensors, communications, user interfaces, and power functions in compact, energy-sensitive systems.
The EFM32TG110F8-QFN24 reaches 32 MHz and includes two 16-bit timers, AES and operational-amplifier resources identified by the distributor listings, and 17 digital I/O pins. Its 8 kB Flash supports a modest embedded program image, while 2 kB of RAM provides working memory for control logic and data buffering. The 1.85 V to 3.8 V supply range supports low-voltage embedded systems.
The ARM Cortex-M3 processor provides a 32-bit RISC architecture and can achieve as much as 1.25 Dhrystone MIPS/MHz, according to the EFM32TG110 datasheet hosted by Keil. The Cortex-M3 also includes a Memory Protection Unit supporting up to eight memory segments and a Wake-up Interrupt Controller for interrupts generated while the processor sleeps.
Typical uses include compact industrial sensors, energy-conscious IoT nodes, wearable accessories, low-power instrumentation, and connected peripherals. Developers can use the 17 available digital I/O pins for sensors, actuators, status indicators, and serial interfaces, while the timers support periodic measurement, timing, or pulse-related tasks.
The principal design consideration is the small memory footprint. Firmware must fit within 8 kB of Flash and its working data within 2 kB of RAM, so code size, library use, stack depth, and interrupt handling should be checked early. Hardware design should follow Silicon Labs guidance in AN0002 EFM32 Hardware Design Considerations.

Typische Anwendungen
EFM32TG110F8-QFN24 ist geeignet für 6 Anwendungs: Energy-Sensitive IoT Sensor Node, Compact Industrial Monitoring Controller, Low-Power Wearable Accessory, Battery-Powered Data Logger, Simple Motor or Actuator Control, Embedded Instrumentation Front End.
Energy-Sensitive IoT Sensor Node
The EFM32TG110F8-QFN24 fits compact IoT sensor nodes where a 32 MHz ARM Cortex-M3 must coexist with strict memory and power constraints. Its 8 kB Flash and 2 kB RAM are sufficient for a tightly organized firmware image that samples a sensor, filters data, and wakes briefly for communication. The manufacturer's 17 digital I/O pins provide flexible connections for sensors, interrupts, and status indicators, while fast wake-up and energy-saving modes can reduce inactive power. The main constraint is firmware capacity: organize drivers and protocols for the 8 kB Flash boundary and use the 2 kB RAM with a checked stack-depth budget.
Empfohlen
Compact Industrial Monitoring Controller
The EFM32TG110F8-QFN24 can monitor simple industrial signals in a compact control module because it combines a 32 MHz Cortex-M3 with 17 digital I/O pins and two 16-bit timers. Those timers can support periodic counting, sampling intervals, or actuator timing, while the digital I/O can handle discrete sensors and indicators. Its 1.85 V to 3.8 V operating range supports low-voltage circuitry, but the designer must add level translation for 5 V industrial signals. Firmware size requires early budgeting because the MCU provides 8 kB Flash and only 2 kB RAM.
Empfohlen
Low-Power Wearable Accessory
The EFM32TG110F8-QFN24 is appropriate for a wearable accessory that performs occasional sensing and control without requiring a large processor. Its low-energy design techniques, fast wake-up capability, and energy-saving modes support duty-cycled operation, while the 24-QFN 5 x 5 mm package limits board area. The 17 digital I/O pins can operate switches, haptic elements, or status LEDs. Because 8 kB Flash and 2 kB RAM are modest, use a slim firmware architecture, avoid heavy application frameworks, and verify regulator quiescent current alongside MCU sleep current to determine realistic battery life.
Empfohlen
Battery-Powered Data Logger
The EFM32TG110F8-QFN24 suits a battery-powered data logger when the required measurements and storage code fit within 8 kB Flash and 2 kB RAM. The two 16-bit timers can establish periodic sample timing, and fast wake-up lets the processor leave a low-power state when a measurement event occurs. Store only essential samples locally or transmit them through a separate low-power radio, because a complex wireless stack is unlikely to fit the available program memory. Validate the total sleep current, sensor standby current, and wake-up timing rather than relying on the MCU's headline 32 MHz clock specification.
Empfohlen
Simple Motor or Actuator Control
The EFM32TG110F8-QFN24 can serve as the timing and logic controller for a compact actuator system that does not require a large motor-control peripheral set. Its two 16-bit timers provide periodic control timing, and 17 digital I/O pins can interface with position sensors, switches, or drive-control signals. The 32 MHz Cortex-M3 executes the control loop, although power transistors and current protection must be placed outside the MCU. Validate timer resolution, PWM-capable pins, thermal conditions, and output timing from the complete datasheet before finalizing a motor-control topology.
Empfohlen
Embedded Instrumentation Front End
The EFM32TG110F8-QFN24 can manage a small instrumentation front end when measurements require discrete sensing, timed acquisition, and local status control. The 17 digital I/O pins and two 16-bit timers support sensor multiplexing and measurement cadence, while the listed operational-amplifier resource provides an analog function for suitable signal-conditioning requirements. Its small 24-QFN footprint assists compact instruments, but designers must respect the 2 kB RAM limit and optimize buffers. Verify the exact analog-pin assignments and electrical limits in the EFM32TG110 datasheet before routing precision signals.

Designhinweise
Follow Silicon Labs AN0002 EFM32 Hardware Design Considerations when laying out the EFM32TG110F8-QFN24 PCB. Place all required decoupling and bulk capacitors close to their corresponding power pins, use the exposed pad for the package's thermal and electrical requirements, and avoid routing noisy switching or high-current paths adjacent to sensitive analog inputs. The verified result confirms that the device is a 24-QFN 5 x 5 mm package, so courtyard, land pattern, paste volume, and exposed-pad assembly should be checked against the final package drawing rather than inferred from generic QFN guidance.
Design the power tree for the verified 1.85 V to 3.8 V operating range and account for the 2 kB RAM and 8 kB Flash constraints during firmware planning. Use a regulator with adequate startup, transient response, and quiescent current for a low-power design. Estimated: at a 3.3 V supply, average current equal to 1 mA would dissipate approximately 3.3 mW in the MCU; this is an arithmetic illustration, not a datasheet operating-current specification. Measure real active and sleep current because peripheral use and wake-up frequency dominate battery life.
Do not treat a generic 24-pin QFN or another Cortex-M3 as a drop-in replacement without checking every pin. Verify power pins, ground and exposed-pad connections, reset, debug, clock, boot configuration, and every peripheral signal against the EFM32TG110 datasheet. Also check firmware migration: the ARM Cortex-M3 instruction set alone does not guarantee identical peripheral registers, interrupts, clock-tree behavior, or low-power wake-up sequences.
Keep the 32 MHz clock path and sensitive analog routing away from the EFM32TG110F8-QFN24's exposed-pad region and high-current return paths. If an external crystal is used, follow the layout and loading requirements in the manufacturer documentation and keep the oscillator area quiet. The listed operational-amplifier resource may support local analog conditioning, but its exact pin mapping, input range, stability, and usable bandwidth must be confirmed from the datasheet before treating it as a precision analog front end.
Compliance-Informationen
The supplied verified product, distributor, and datasheet results do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. No compliance qualification was inferred.
