部品番号: EFM32TG110F4-D-QFN24 ✓ 生産中EFM32TG110F4-D-QFN24 概要
A microcontroller is a programmable semiconductor that integrates a processor core, memory, and peripherals into one package. The EFM32TG110 belongs to the Tiny Gecko family, a low-power 32-bit MCU platform suited to battery-powered and portable equipment. This device combines the ARM Cortex-M3 instruction set with energy-saving modes, fast wake-up behavior, and autonomous peripheral capabilities.
The primary verified features of the EFM32TG110F4-D-QFN24 include a maximum CPU speed of 32 MHz, 4 kB of Flash, 2 kB of RAM, and 17 digital I/O pins. Its hardware also provides two 16-bit timers, an AES-capable feature set identified in distributor listings, an operational amplifier, a temperature sensor, a voltage comparator, and a flexible clock system that includes a 32.768 kHz crystal oscillator option.
The device is positioned as a low-power platform with run consumption specified by the manufacturer datasheet as 150 uA/MHz and Stop-mode consumption as low as 0.6 uA. Its architecture allows peripherals to perform routine measurements, comparisons, timing, and communications without continuous CPU intervention. This can reduce processing demand in systems that periodically wake, acquire information, transmit data, and return to a low-energy state.
Typical uses include sensor nodes, compact industrial controls, wearable accessories, connected measurement equipment, and low-power embedded products. The 5 x 5 mm 24-QFN package supports space-constrained designs, while the 17 digital I/O pins provide connections for sensors, indicators, communications, and control signals. The limited 4 kB Flash and 2 kB RAM make firmware and application data sizing particularly important.
When designing around this MCU, connect AVDD_x, VDD_DREG, and IOVDD_x as directed by the manufacturer hardware-design guidance and preserve the recommended decoupling layout. Confirm startup behavior, clock selection, exposed-pad soldering, and peripheral pin assignments against the EFM32TG110 datasheet before releasing a PCB for production.
This product record combines verified manufacturer specifications, distributor pricing, same-family drop-in alternatives, and practical design guidance. It emphasizes the constraints that matter when selecting a 4 kB-Flash, 2 kB-RAM Cortex-M3 MCU for compact and energy-conscious equipment.

主な用途
EFM32TG110F4-D-QFN24 の用途: 6 件s: Battery-Powered Sensor Node, Compact Industrial Control Module, Wearable Accessory Controller, Portable Measurement Device, Low-Power Wireless Accessory, Compact Energy Metering Module.
Battery-Powered Sensor Node
The EFM32TG110F4-D-QFN24 fits compact sensor nodes because its 32 MHz ARM Cortex-M3 core provides processing speed while the Tiny Gecko platform supports Stop operation down to 0.6 uA and Run operation around 150 uA/MHz. Its integrated temperature sensor, voltage comparator, 17 digital I/O pins, and two 16-bit timers can reduce the number of external components needed for periodic environmental measurements and threshold decisions. The designer should operate the MCU mainly in Stop mode, wake it for short acquisition cycles, and retain sensor readings in the available 2 kB RAM. Firmware must remain within the 4 kB Flash limit, so an F16 or F32 family variant may be preferable when protocol libraries or buffered data make the original F4 too constrained.
おすすめ
Compact Industrial Control Module
The EFM32TG110F4-D-QFN24 is suitable for compact industrial controls where a 5 x 5 mm 24-QFN footprint saves board area without sacrificing a 32-bit processor. Its 17 digital I/O pins can support digital inputs, status outputs, and control functions, while the two 16-bit timers provide dedicated timing resources for periodic sampling or actuator sequencing. The 1.98 V to 3.8 V operating range accommodates low-voltage embedded rails, and the integrated operational amplifier, comparator, and temperature sensor can assist front-end conditioning. Because the MCU is not specified here for extended industrial temperature exposure, its operating-temperature rating must be checked before deployment. The 4 kB Flash capacity also favors simple control logic rather than large protocol stacks.
おすすめ
Wearable Accessory Controller
The EFM32TG110F4-D-QFN24 can manage a wearable accessory that periodically connects to a host or processes a simple user input. Its 17 digital I/O pins are useful for buttons, indicators, haptic signaling, and external status detection, while the Cortex-M3 core provides more headroom than an 8-bit controller without requiring the memory of a larger system. The Tiny Gecko energy-saving modes support designs that spend most of their time waiting for an event. A key trade-off is the small 4 kB Flash and 2 kB RAM, which limits code size and data buffering. The 24-QFN, 5 x 5 mm package supports compact assemblies, but exposed-pad soldering and local decoupling must follow the manufacturer's layout guidance.
おすすめ
Portable Measurement Device
The EFM32TG110F4-D-QFN24 is appropriate for portable measurement equipment where an internal temperature sensor and voltage comparator can support local diagnostics. Its two 16-bit timers and 32 MHz processing rate can coordinate sampling, threshold checks, and compact display or communication updates. The 24-QFN package limits board area, which is useful in handheld instruments, while the 1.98 V to 3.8 V supply range supports integration with low-voltage power systems. Designers should use the 2 kB RAM carefully and avoid demanding data sets that cannot be streamed or processed incrementally. If calibration tables or communication firmware exceed the 4 kB Flash budget, EFM32TG110F16-D-QFN24 or EFM32TG110F32-D-QFN24 provides additional program space in the same family and package format.
おすすめ
Low-Power Wireless Accessory
The EFM32TG110F4-D-QFN24 can serve as the control and low-energy processing element in a compact wireless accessory. The MCU coordinates radio-control logic through its 17 I/O pins and uses its timers for periodic timing functions while the EFM32TG platform handles low-power states and rapid wake-up behavior. Its 32 MHz Cortex-M3 core is suitable for packet handling and local logic, although the final wireless interface and its current draw are not specified by the supplied data. The designer should treat 4 kB Flash and 2 kB RAM as strict design budgets, use the Stop-mode capability where practical, and verify that the complete radio firmware fits. The F16 or F32 memory variant may be necessary once a production wireless stack is selected.
おすすめ
Compact Energy Metering Module
The EFM32TG110F4-D-QFN24 is a reasonable fit for a compact energy-metering module that periodically samples sensors, evaluates thresholds, and records events. The integrated voltage comparator supports threshold-based monitoring, while the temperature sensor can provide local condition information. Two 16-bit timers help structure periodic sampling intervals, and the 17 digital I/O pins provide host communication, status indication, or alarm signaling. Its Stop-mode current can reach 0.6 uA, which is valuable when the module is mostly idle, although total system consumption also depends on sensors and power-supply efficiency. The 2 kB RAM and 4 kB Flash limit historical storage and firmware complexity. For larger calibration tables or protocol code, select the 16 kB or 32 kB Flash family variant.

設計ノート
Follow the Silicon Labs EFM32TG hardware-design guidance when connecting AVDD_x, VDD_DREG, and IOVDD_x. The family documentation notes that these supplies are connected together at the PCB level, with optional filtering, and the exposed pad must receive the package-appropriate land pattern and soldering process. Place local decoupling close to the associated supply balls, provide a continuous ground reference, and confirm the exact exposed-pad connection against the official pin table before fabrication.
Budget the 1.98 V to 3.8 V operating range during rail planning, including startup, transient, and sleep conditions. The manufacturer reports as little as 0.6 uA in Stop mode and 150 uA/MHz in Run mode, but those figures do not include external sensors, radio circuitry, or regulator losses. Measure the complete duty cycle because a system that wakes frequently may consume substantially more energy than a device remaining in Stop mode. Decoupling and filtering should follow the manufacturer recommendations rather than relying solely on the average current figures.
Do not treat a higher-Flash member of the EFM32TG110 family as automatically interchangeable. Although EFM32TG110F8-D-QFN24, EFM32TG110F16-D-QFN24, EFM32TG110F32-D-QFN24, and EFM32TG110F64-D-QFN24 use the same 24-QFN family format, verify the manufacturer pin table, memory organization, startup behavior, and exposed-pad requirements. The original device also has only 4 kB Flash and 2 kB RAM, so check linker placement and runtime buffers before allowing a larger-memory alternative into an existing design.
Keep sensitive analog inputs, reference connections, and the operational amplifier or comparator paths away from fast digital return currents and switching nodes. The supplied sources identify an integrated operational amplifier, voltage comparator, and temperature sensor, but they do not provide a complete layout reference. Use a continuous ground plane, route sensitive signals over uninterrupted reference planes, and keep the 32.768 kHz oscillator area free from noisy power and digital traces. Final component placement and grounding should be checked against the Silicon Labs datasheet and hardware-design guidance.
コンプライアンス情報
The supplied verified sources do not provide explicit RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification statements. AEC-Q100 is treated as not applicable because this product is positioned as a general-purpose MCU rather than a verified automotive-qualified variant.
