EFM32ZG110F4-QFN24T - 24MHz Cortex-M0+ 4KB MCU | Silicon Labs
MPN： EFM32ZG110F4-QFN24T ✓ 啟用中EFM32ZG110F4-QFN24T 概覽
A microcontroller is an integrated semiconductor that combines a processor core, program memory, data memory, and peripherals in one package. The Zero Gecko family uses an ARM Cortex-M0+ core within the MCU hierarchy, while its low-power platform adds energy-saving modes, fast wake-up behavior, and autonomous peripheral operation. This makes it suitable for battery-powered sensing, metering, and small control systems that must respond quickly without continuously consuming maximum power.
The EFM32ZG110F4-QFN24T combines a 24 MHz processor with 4 KB of Flash and 2 KB of SRAM. Silicon Labs specifies as little as 0.5 microamp in Stop mode and 114 microamps per MHz in Run mode, supporting designs that spend most of their operating life in a low-power state. Its 17 digital I/O pins provide connections for sensors, switches, indicators, and control signals within the limited footprint of a 5 x 5 mm QFN package.
Two 16-bit timers support periodic timing, input capture, output compare, and basic pulse-width modulation functions. The Zero Gecko platform also integrates analog and communications peripherals around the 32-bit ARM Cortex-M0+ processor. The constrained 4 KB memory footprint favors compact firmware, while the 24 MHz clock rate provides adequate headroom for control loops, low-rate serial communication, and sensor aggregation rather than graphics or high-throughput data processing.
Typical applications include compact energy meters, gas and water sensing nodes, battery-operated industrial monitors, environmental sensors, and wearable or IoT accessory controllers. The 24-QFN package also supports space-constrained products in which board area, supply voltage, and standby current are more important than large program storage. The -QFN24T ordering code identifies the manufacturer's tape-and-reel package format.
Designers should verify the exact exposed-pad connection, decoupling requirements, and available peripheral pins against the EFM32ZG data sheet before layout release. Because the Flash and RAM capacities are small, firmware architecture, constant-data placement, and peripheral initialization sequence should be reviewed early rather than after application code is complete.
This page consolidates manufacturer specifications, distributor availability references, same-footprint Zero Gecko alternatives, and application-specific engineering guidance that is not presented as a single block in the manufacturer data sheet.

典型應用
EFM32ZG110F4-QFN24T 適用於 6 應用s: Battery-Powered Environmental Sensor, Gas and Water Metering Node, Portable Wearable Accessory, Compact Industrial Condition Monitor, Smart Home Sensor Node, Low-Power Remote Controller.
Battery-Powered Environmental Sensor
The EFM32ZG110F4-QFN24T fits compact environmental sensors because its 24 MHz ARM Cortex-M0+ core can sample inputs, filter readings, and manage low-power duty cycles while consuming only 0.5 microamp in Stop mode. Place the MCU beside the sensor front end and use its timers for periodic wake-up and sampling intervals. The 2 KB RAM and 4 KB Flash limit firmware complexity, so the design should favor compact drivers, scaled sensor values, and minimal local buffering. A key trade-off is that the 4 KB Flash budget can become restrictive once calibration tables, diagnostics, and protocol updates are added.
推薦
Gas and Water Metering Node
The EFM32ZG110F4-QFN24T is appropriate for gas and water metering nodes that periodically read sensors, perform pulse counting, and report results over a low-rate communications link. Its two 16-bit timers can support metering intervals or input-capture functions, while 114 microamps per MHz in Run mode limits active current when the radio remains off. The small 5 x 5 mm 24-QFN footprint preserves board area in a remote transmitter. Designers should budget the 4 KB Flash for the metering task and use a separate radio or communications component if the selected protocol stack exceeds that capacity.
推薦
Portable Wearable Accessory
The EFM32ZG110F4-QFN24T can manage haptic, button, and simple sensor functions in a wearable accessory where board area and standby consumption are tightly constrained. Its 0.5 microamp Stop-mode current allows the controller to remain available without continuously running the 24 MHz core, and the 17 digital I/O pins can support switches, indicators, and peripheral connections. The 24-QFN 5 x 5 mm package also leaves room for a battery and radio. Designers should use event-driven firmware, because the 4 KB Flash and 2 KB RAM favor small accessory roles rather than complex user-interface or graphics processing.
推薦
Compact Industrial Condition Monitor
The EFM32ZG110F4-QFN24T is well suited to a small industrial condition-monitoring module that samples switches or analog-derived conditions and logs state changes locally. Its Cortex-M0+ processor handles interrupts, timing, and peripheral coordination at up to 24 MHz, while the Stop mode reduces consumption between measurements. The two 16-bit timers provide the basis for periodic acquisition and event timing. Because the device offers only 4 KB of Flash, avoid local file systems and heavy protocol stacks on the MCU; use a communications companion when a standard network stack is required.
推薦
Smart Home Sensor Node
The EFM32ZG110F4-QFN24T supports a smart-home sensor node that periodically reads environmental or occupancy inputs and wakes for brief processing intervals. The 1.98 V to 3.8 V supply range allows operation from 2 V or 3.3 V system rails, and the 24-QFN package simplifies compact radio-and-sensor board construction. Two 16-bit timers are useful for debouncing, sampling intervals, and motor or indicator timing. The design trade-off is the 4 KB program-memory limit: keep the node firmware focused and offload standard wireless protocols or complex edge analytics to a companion processor.
推薦
Low-Power Remote Controller
The EFM32ZG110F4-QFN24T can act as the low-power host for a compact remote controller that scans buttons, drives an indicator, and coordinates a radio link. The 17 digital I/O pins provide useful control resources for switches and status signals, and the 0.5 microamp Stop-mode figure supports long standby periods. The controller can remain in a low-power state until a user event triggers the 24 MHz processor. Designers should account for the limited 2 KB RAM when buffering received data and for the small Flash footprint when adding command mapping or update support.

設計說明
The EFM32ZG data sheet specifies operation down to 0.5 microamp in Stop mode and 114 microamps per MHz in Run mode. Size the power budget around the average operating current rather than the peak run current: estimate the duty cycle, account for sensor and radio loads, and include brownout behavior during battery changes. Confirm that the selected regulator can start the 24 MHz processor and maintain the 1.98 V to 3.8 V supply range without excessive ripple.
The 24-QFN 5 x 5 mm package needs a land pattern and thermal-via strategy based on the official package drawing. Place all required decoupling capacitance close to the supply pins and keep sensitive analog inputs away from switching nodes and fast digital routes. The exposed-pad connection must be taken directly from the manufacturer drawing rather than inferred from a generic QFN24 footprint, since exposed-pad connections are device-specific.
Do not treat the larger-Flash Zero Gecko devices as unconditional behavioral replacements. The EFM32ZG110F8, F16, and F32 candidates provide 8, 16, and 32 KB respectively, compared with 4 KB on the target. A firmware image that fits the target may boot differently if startup code, vector tables, or flash-region assumptions differ, and the ZG108 configuration may differ in mixed-signal pin assignments. Review the device comparison tables and pin tables before migrating.
