Référence : EFM32ZG108F16-QFN24 ✓ ActifEFM32ZG108F16-QFN24 Présentation
A microcontroller is a programmable semiconductor that combines a processor core, memory, and peripherals on one integrated circuit. The EFM32ZG family belongs to the ARM Cortex-M0+ microcontroller hierarchy, where the Cortex-M0+ core provides an efficient 32-bit architecture for embedded control, sensor, and communication products. The Zero Gecko platform emphasizes energy efficiency through low-power modes, fast wake-up times, and autonomous peripheral operation. This makes the EFM32ZG108F16-QFN24 suitable for battery-powered equipment where average energy use is more important than maximum processing throughput.
The EFM32ZG108F16-QFN24 combines 16 kB of Flash with 4 kB of RAM and 17 digital I/O pins in a compact 5x5 mm QFN package. Its two 16-bit timers provide dedicated timing resources for periodic sensing, motor control, or signal generation. The integrated hardware is intended to reduce the number of external components in small embedded products while retaining the low-power characteristics associated with the Zero Gecko family.
The verified manufacturer datasheet describes the EFM32ZG family as consuming as little as 0.5 microamp in Stop mode and 114 microamps per megahertz in Run mode. These figures show the family-level power behavior: the Stop-mode figure is important for duty-cycled battery systems, while the Run-mode figure helps estimate active processing energy. The device also includes low-energy techniques, fast wake-up times, energy-saving modes, autonomous peripherals, and high analog integration.
Typical applications include low-power sensor nodes, compact industrial monitoring devices, battery-operated accessories, portable measurement products, and connected embedded controls. A sensor node can keep the processor stopped for most of its operating cycle, wake on an external event, acquire a measurement, process it, and return to Stop mode. For motor or timing functions, the two 16-bit timers can offload periodic operations and reduce the need for continuous software polling.
When designing a board around this MCU, preserve the exposed-pad and QFN land-pattern requirements and decouple the supply pins close to the device. Confirm the exact pin multiplexing, oscillator requirements, and exposed-pad connection against the manufacturer datasheet before layout release. The QFN package is compact, so thermal performance depends on the PCB copper area and the exposed pad rather than on package size alone.
This page combines verified manufacturer and distributor information, a practical comparison of same-package alternatives, and engineering guidance for low-power PCB design. It is intended to help engineers identify the correct Zero Gecko variant, plan power budgets, and move from component selection to a manufacturable 24-QFN design.

Applications typiques
EFM32ZG108F16-QFN24 convient pour 6 applications: Battery-Powered Sensor Node, Industrial Environmental Monitoring, Portable Measurement Instrument, Low-Power Motor Control, Smart Home Sensor Interface, Compact Consumer Accessory.
Battery-Powered Sensor Node
The EFM32ZG108F16-QFN24 fits battery-powered sensor nodes because its 24 MHz ARM Cortex-M0+ core provides compact control processing while the Zero Gecko family supports Stop-mode consumption as low as 0.5 microamp. The device can remain in a low-energy state between measurements, wake quickly for acquisition, and process the result without keeping the processor continuously active. Its 16 kB Flash and 4 kB RAM provide space for embedded firmware, while 17 digital I/O pins support sensors, interrupt inputs, and status indicators. Final energy use depends on the external sensor and radio, but the MCU's low-power architecture reduces the processing portion of the duty cycle.
Recommandé
Industrial Environmental Monitoring
The EFM32ZG108F16-QFN24 is suitable for industrial environmental monitoring systems that periodically read temperature, humidity, gas, or digital sensors. Its 17 digital I/O pins provide interfaces for discrete sensors and alarms, and the two 16-bit timers can support periodic sampling or timeout functions. The 24 MHz Cortex-M0+ core is suitable for local filtering, threshold checks, and data preparation. Stop-mode operation can reduce energy consumption during long measurement intervals, although an industrial enclosure may impose higher leakage and temperature limits than a battery-only product.
Recommandé
Portable Measurement Instrument
The EFM32ZG108F16-QFN24 supports compact portable instruments where a dedicated processor must control analog measurement front ends, user inputs, and data storage. The 24 MHz Cortex-M0+ core can supervise conversions and calculations, while 16 kB Flash stores the application firmware and 4 kB RAM supports transient working data. Two 16-bit timers offer flexible timing resources for sampling cadence and user-interface timing. The 24-QFN package helps preserve compactness, but exposed-pad layout and local supply decoupling remain essential for stable analog-adjacent measurements.
Recommandé
Low-Power Motor Control
The EFM32ZG108F16-QFN24 can manage compact low-power motor-control systems that rely on periodic position, speed, or timing updates. Its two 16-bit timers provide hardware timing for pulse generation or input capture, while the 24 MHz Cortex-M0+ core executes control and fault-handling logic. The 17 digital I/O pins can accommodate control signals, Hall inputs, and status outputs. This arrangement is most appropriate for modest motor loads where external transistors, current sensing, and protection are included in the power stage.
Recommandé
Smart Home Sensor Interface
The EFM32ZG108F16-QFN24 can act as the local controller for a compact smart-home sensor or actuator interface. Its 17 digital I/O pins allow connection of switches, occupancy inputs, alarms, and status LEDs, while the two 16-bit timers help sequence repeated actions. Fast wake-up behavior and the availability of low-energy modes help conserve power in duty-cycled endpoints. For a connected product, the designer should budget additional flash and RAM for protocol handling or choose a larger-memory MCU when the target stack cannot fit within the verified 16 kB Flash and 4 kB RAM.
Recommandé
Compact Consumer Accessory
The EFM32ZG108F16-QFN24 fits compact consumer accessories that require responsive local control, modest user interfaces, and low standby power. The small 24-QFN package supports space-constrained products, and the Cortex-M0+ core can manage button inputs, LED indicators, simple timers, and accessory state machines. Family-level Stop-mode current of 0.5 microamp is valuable for battery-operated products, while 114 microamps per MHz provides a basis for active-current estimates. Product qualification, EMC requirements, and the exact operating-temperature range must be checked against the selected ordering code.

Notes de conception
Use the manufacturer QFN-24 land pattern and connect the exposed pad according to the EFM32ZG data sheet. Place the device-side supply bypass capacitors close to their associated supply pins, with the shortest possible return path through the ground plane. The verified excerpts do not specify capacitor values, so select them from the datasheet's recommended application circuit rather than guessing. Keep analog and high-impedance sensor routes away from switching-node and motor-drive traces.
Estimated: active current at 24 MHz is approximately 114 microamps per MHz multiplied by 24, or 2.736 mA, using the verified family-level Run-mode figure. This is an estimate and excludes peripherals, analog blocks, external load, and temperature effects. Compare that result with the device duty cycle before selecting a battery. For sleep-dominated designs, include the 0.5 microamp Stop-mode family figure, sensor current, leakage, and wake-up energy in the total energy budget.
The EFM32ZG108F16-QFN24 has 17 digital I/O pins in a 24-QFN package, so pin multiplexing is likely to influence board design. Freeze the peripheral assignment before routing and preserve alternate-function requirements for debugging, boot, communications, or timers. The complete numbered pinout is not present in the supplied excerpts; therefore, do not assign signals from package count alone. Verify every pin and exposed-pad connection against the manufacturer datasheet and the final firmware configuration.
Informations de conformité
The supplied manufacturer and distributor excerpts do not explicitly state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status for the exact ordering code. AEC-Q100 is not applicable because this is a microcontroller rather than an automotive-qualified device; the -B suffix meaning was not available in the supplied excerpts.
