EFM32ZG110F8-B-QFN24 - 24MHz ARM Cortex-M0+ MCU | Silicon Labs
N.º da peça: EFM32ZG110F8-B-QFN24 ✓ AtivoEFM32ZG110F8-B-QFN24 Visão geral
A microcontroller is a programmable semiconductor that integrates a CPU, memory, and peripherals into one control device. In the technology hierarchy, the EFM32ZG110 belongs to the ARM Cortex-M0+ class of 32-bit microcontrollers, which sit above 8-bit controllers in processing capability while retaining a simple embedded-system architecture. Its memory, GPIO, timers, analog functions, and communication peripherals make it suitable for control, sensing, metering, and low-power IoT endpoints.
The device operates at up to 24 MHz and provides 8 kB Flash for firmware and 2 kB RAM for working data. Its 17 digital I/O pins support external sensors, switches, indicators, and actuators. Two 16-bit timers are useful for periodic generation, input capture, timing, and basic motor or dimming control. The 24-QFN package supports compact, high-density PCB layouts in energy-sensitive industrial and embedded applications.
The EFM32ZG platform emphasizes low-power operation and short wake-up times. According to the Silicon Labs EFM32ZG datasheet, the family can consume as little as 0.5 microampere in Stop mode and 114 microampere per megahertz in Run mode. This makes the MCU useful in systems that spend most of their operating time asleep, where average current depends strongly on duty cycle, peripheral activity, and wake-up frequency.
Typical uses include smart energy and gas meters, water-monitoring equipment, industrial sensing nodes, compact control panels, and connected low-power sensors. The device can coordinate acquisition and processing through its integrated peripherals while limiting the external component count needed for embedded control. Its 8 kB Flash is appropriate for compact applications with a controlled firmware footprint rather than memory-intensive connectivity stacks.
Hardware design should preserve clean supply decoupling, assign all QFN perimeter pins according to the manufacturer pin-description table, and verify that the exposed-pad connection and PCB thermal design follow the package guidance. Firmware should also use the device's low-energy modes deliberately because measured battery life depends on how often the processor and peripherals wake from sleep.

Aplicações típicas
EFM32ZG110F8-B-QFN24 é adequado para 6 aplicaçãos: Smart Water Metering, Gas and Energy Metering, Industrial Sensor Node, Battery-Powered IoT Endpoint, Compact Control and HMI Panel, Low-Power Motor or Dimming Control.
Smart Water Metering
The EFM32ZG110F8-B-QFN24 fits smart water meters because its 24 MHz Cortex-M0+ core can process pulse, flow, and sensor measurements while the 2 kB RAM accommodates compact working buffers. The 17 digital I/O pins provide connections for meter inputs, status indicators, and valve or alarm controls, while the two 16-bit timers support accurate event counting and periodic sampling. The Zero Gecko family's Stop-mode current can be as low as 0.5 microampere, making deep sleep important for battery-operated metering. Designers should size firmware around the 8 kB Flash limit and confirm that the selected peripheral set meets the utility meter's pulse, tamper, and communications requirements.
Recomendado
Gas and Energy Metering
The EFM32ZG110F8-B-QFN24 is appropriate for gas, electricity, and resource-metering endpoints that combine periodic measurement with long idle periods. Its 24 MHz Cortex-M0+ processor provides enough performance for calibration, compensation, event logging, and communication-control tasks, while two 16-bit timers can support pulse counting and timing functions. Low-power operation is central to the design: the EFM32ZG family can consume 0.5 microampere in Stop mode and 114 microampere per megahertz in Run mode. The 24-QFN 5 x 5 mm footprint also saves board area. The supply design should preserve the 1.98 V to 3.8 V range, and firmware should minimize active time to extend battery service intervals.
Recomendado
Industrial Sensor Node
The EFM32ZG110F8-B-QFN24 works well as the controller in a compact industrial sensor node that periodically reads an analog or digital sensor and drives a local output. Its ADC and AES capabilities support measurement and secure data handling, while 17 digital I/O pins allow digital sensors, discrete inputs, and status signals to share the controller. The 8 kB Flash footprint favors tightly scoped firmware, and the 2 kB RAM is suitable for modest packet or sample buffers. Fast wake-up operation can reduce response delay between scheduled measurements. For reliable deployment, validate the analog range, noise behavior, supply tolerance, and temperature requirements of the complete node rather than treating the general-purpose MCU specifications as node-level guarantees.
Recomendado
Battery-Powered IoT Endpoint
The EFM32ZG110F8-B-QFN24 is suitable for a duty-cycled IoT endpoint that wakes to sample a sensor, process local data, and return to sleep. The Zero Gecko family's Stop-mode consumption can be as low as 0.5 microampere, while Run consumption is listed at 114 microampere per megahertz, providing a useful basis for energy-budget calculations. The 24 MHz Cortex-M0+ core handles compact protocol and control logic without the overhead of a larger processor. Designers must balance the 8 kB Flash limit against communications and update code, use the 17 I/O pins to minimize external switching, and select a regulator that supports the 1.98 V to 3.8 V supply range without excessive standby loss.
Recomendado
Compact Control and HMI Panel
The EFM32ZG110F8-B-QFN24 can manage a compact control panel, status display, keypad, and discrete actuator outputs where a high-performance application processor is unnecessary. Two 16-bit timers provide predictable timing for display refresh, debounce intervals, or output control, and the 17 digital I/O pins can support buttons, indicators, relays, or interface signals. Its 24-QFN 5 x 5 mm package preserves PCB area for the user interface and power system. Because the device has 8 kB Flash and 2 kB RAM, the firmware should avoid heavyweight graphical frameworks and use event-driven operation. A practical design should also use low-power modes when no user interaction occurs and verify peripheral assignments against the QFN24 pin table.
Recomendado
Low-Power Motor or Dimming Control
The EFM32ZG110F8-B-QFN24 can serve as a low-power controller in a small motor, dimming, or timing system where deterministic event control matters more than heavy computation. Its two 16-bit timers support periodic timing, pulse generation, or input capture, and the 17 digital I/O pins can connect control signals, switches, and status feedback. The 24 MHz Cortex-M0+ core provides enough control throughput for compact state machines and safety interlocks while retaining the family's low-power characteristics. In motor applications, validate output switching timing and thermal behavior at the external driver rather than attributing driver losses to the MCU. Firmware should use low-energy modes when the actuator is idle and preserve deterministic timer behavior across sleep transitions.

Notas de projeto
Design the supply for the EFM32ZG110F8-B-QFN24's 1.98 V to 3.8 V operating range and account for startup, sleep, and active current separately. Estimated energy use can be calculated as average current multiplied by time in each operating state, but that figure must use measured firmware timing rather than the 114 microampere/MHz Run value alone. Place the required input capacitors beside the supply and ground pins, and use a regulator whose own quiescent current is acceptable for the battery budget.
Use the Silicon Labs QFN24 land pattern and pin-description table to assign all perimeter connections. Keep the exposed pad electrically consistent with the manufacturer's guidance, provide the required ground or thermal structure, and route sensitive analog inputs away from switching nodes and high-current return paths. The 5 x 5 mm footprint is compact, so pad alignment and solderable land geometry should be checked against the PCB assembly process rather than copied from a generic QFN drawing.
Do not assume that two 24-QFN Gecko devices are interchangeable merely because their packages match. The EFM32ZG110F8-B-QFN24 uses Cortex-M0+ at 24 MHz, while EFM32TG variants use Cortex-M3 and may differ in clocking, peripheral behavior, and firmware requirements. Validate pin multiplexing, interrupt vectors, startup code, debug programming, and application timing before reusing an existing PCB. Also check the F8 versus F4 memory capacity to prevent firmware overflow.
Use the low-energy modes as part of the application architecture, not merely as optional firmware settings. Disable unused peripherals, avoid continuous polling, batch sensor reads, and schedule communication after measurement processing. The family-level Stop current can be as low as 0.5 microampere, but board-level consumption may be dominated by sensors, pull networks, regulators, and indicator drivers. Measure the complete assembled product across each operating state to establish a realistic battery-life estimate.
