部品番号: EFM32ZG210F8-B-QFN32 ✓ 生産中EFM32ZG210F8-B-QFN32 概要
A microcontroller is a programmable system-on-chip that integrates a processor core, memory, and peripherals into one package. The EFM32 Zero Gecko family belongs to the hierarchy of 32-bit microcontroller, embedded processor, and low-power semiconductor devices. The ARM Cortex-M0+ architecture provides a compact instruction set suited to control-intensive systems that prioritize energy efficiency, predictable response, and low system complexity.
Key features include a maximum operating frequency of 24 MHz, 8 KB Flash, and 2 KB RAM. Silicon Labs specifies run-mode consumption as low as 114 uA/MHz and stop-mode consumption as low as 0.5 uA. The device also provides autonomous peripherals, analog integration, energy-saving modes, and fast wake-up behavior. These characteristics make it useful where the controller must monitor sensors, update outputs, and remain available for infrequent communication without continuously loading a battery.
The EFM32ZG210F8-B-QFN32 is based on the 32-bit ARM Cortex-M0+ processor and provides 24 digital I/O pins for external sensing, switching, and control functions. Its 2 x 16-bit timers support periodic timing and event generation. The integrated analog and peripheral resources reduce the need for external components in compact sensing and energy-harvesting products.
Typical applications include smart energy meters, water and gas meters, industrial sensor nodes, wearable devices, and low-power IoT equipment. In these systems, the 8 KB Flash capacity suits compact firmware, while the 2 KB RAM allows moderate protocol buffering and peripheral management without requiring a larger microcontroller.
Designers should follow Silicon Labs hardware guidance in application note AN0002, EFM32 Hardware Design Considerations. In particular, the AVDD_x, VDD_DREG, and IOVDD_x pins must be connected together at the PCB level, with an optional filter, and supply decoupling should follow the manufacturer reference layout.
This page combines manufacturer specifications, distributor availability references, same-package Zero Gecko options, and practical hardware-design notes to support part selection and PCB planning beyond a distributor listing alone.

主な用途
EFM32ZG210F8-B-QFN32 の用途: 6 件s: Smart Water and Gas Metering, Industrial Sensor and Condition-Monitoring Node, Battery-Powered IoT Sensor, Wearable and Health-Tracking Device, Energy-Harvesting Device, Compact HVAC and Appliance Controller.
Smart Water and Gas Metering
The EFM32ZG210F8-B-QFN32 suits metering nodes that must capture pulse, sensor, or flow information while keeping energy use low. Its 24 MHz ARM Cortex-M0+ core and 2 x 16-bit timers can handle acquisition and periodic measurement tasks, while the 2 KB RAM is adequate for compact buffering. Silicon Labs specifies stop-mode consumption as low as 0.5 uA and run-mode consumption of 114 uA/MHz, supporting long maintenance intervals in battery-powered installations. The 32-QFN 6 x 6 mm package also reduces board area in compact meter electronics. Firmware should remain within the 8 KB Flash budget and use the device's autonomous peripheral features to avoid unnecessary CPU wake-ups.
おすすめ
Industrial Sensor and Condition-Monitoring Node
The EFM32ZG210F8-B-QFN32 is appropriate for compact industrial nodes that read sensors, evaluate thresholds, and report events through a low-rate serial interface. Its 24 digital I/O pins provide flexible connections for digital sensors, interrupt lines, and status indicators, while the integrated analog resources reduce board complexity. The 114 uA/MHz run-mode figure makes duty-cycled acquisition practical in remotely powered equipment. Designers should use stop or shutoff operation between measurements, retain only required state, and follow the EFM32ZG hardware design guidance for supply filtering and decoupling.
おすすめ
Battery-Powered IoT Sensor
The EFM32ZG210F8-B-QFN32 fits small wireless-sensor designs where standby energy dominates the battery budget. Silicon Labs highlights 0.5 uA stop-mode consumption, 114 uA/MHz in run mode, fast wake-up, and autonomous peripherals as defining characteristics of the Zero Gecko platform. These features let the processor remain asleep until a sensor or communications event requires service. The 8 KB Flash footprint suits simple firmware, while 24 I/O pins support environmental sensing and control outputs. System-level energy results still depend on the radio, sensor, and power-conversion circuit, so the MCU should not be considered the only load in the power budget.
おすすめ
Wearable and Health-Tracking Device
The EFM32ZG210F8-B-QFN32 can serve as the low-power controller in a wearable or health-tracking accessory where limited Flash and strict standby current are acceptable. Its 24 MHz Cortex-M0+ core supports event processing, and the 24 I/O pins can accommodate motion inputs, buttons, and indicator outputs. The compact 32-QFN 6 x 6 mm package is useful in space-constrained products. Firmware should avoid polling and rely on interrupt-driven or peripheral-driven operation to approach the low-power behavior described in the EFM32ZG datasheet. For applications requiring large data buffering, remote updates, or complex UI state, a higher-memory Zero Gecko option may be necessary.
おすすめ
Energy-Harvesting Device
The EFM32ZG210F8-B-QFN32 is a reasonable controller for energy-harvesting systems because its low-power operating modes reduce the energy required between intermittent energy-supply events. The 114 uA/MHz run figure, 0.5 uA stop specification, and fast wake-up behavior help the processor respond after harvested energy becomes available. Its small 32-QFN package also leaves board area for harvesting and energy-storage components. Designers must confirm the minimum operating voltage, manage startup and brownout behavior, and prevent peripheral leakage from negating the MCU's low-power advantage.
おすすめ
Compact HVAC and Appliance Controller
The EFM32ZG210F8-B-QFN32 fits small appliance controllers that monitor switches, sensors, and simple timing sequences without requiring a large user interface. The 2 x 16-bit timers support periodic tasks and motor or valve timing, while the 24 I/O pins provide adequate control connectivity for a compact board. The 8 KB Flash limit favors straightforward, deterministic firmware with minimal library overhead. During design, apply the manufacturer's supply-routing requirements and isolate noisy switching stages appropriately so microcontroller timing and analog measurements remain dependable.

設計ノート
Follow Silicon Labs application note AN0002, EFM32 Hardware Design Considerations, when planning the power network. The EFM32ZG210 requires AVDD_x, VDD_DREG, and IOVDD_x to be connected together at the PCB level, with an optional filter. Place the required decoupling capacitors close to their assigned pins and preserve the manufacturer's return-path geometry. Avoid adding long shared traces between the supply groups because that can increase supply noise and undermine the low-power performance of the MCU.
Reserve a compact decoupling and filtering network around the 32-QFN device rather than relying on a distant bulk capacitor. The verified EFM32ZG210 documentation explicitly calls out the common connection of AVDD_x, VDD_DREG, and IOVDD_x at the PCB level. Use the manufacturer's reference layout to determine capacitor placement and exposed-pad or thermal-via requirements. Keep high-current switching nodes and inductive components away from analog and oscillator connections to reduce coupling into the measurement and timing paths.
Do not select a higher Flash-density device solely because it shares the 32-QFN package; first confirm the exact pin arrangement and retained functions required by the board. The verified results identify the EFM32ZG210 family but do not provide a complete cross-density pin table. Also confirm the meaning of the -B ordering suffix and the packing suffix when substituting parts. This is especially important for production traceability because memory-density and revision suffixes may alter programming, qualification, or purchasing requirements.
Estimated: at 24 MHz operation, the manufacturer figure of 114 uA/MHz corresponds to approximately 2.74 mA of CPU run current. This is a device-level estimate using 24 MHz multiplied by 114 uA/MHz and excludes analog blocks, peripherals, flash execution overhead, and external loads. Use it as an initial activity-budget check rather than as a datasheet operating-current specification, and measure the finished application under its real duty cycle.
コンプライアンス情報
The supplied verified results identify environmental and automotive qualifications but do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for this exact ordering code. Compliance fields therefore remain unknown rather than assumed. Confirm current declarations with Silicon Labs before production release.
