EFM32ZG110F4-QFN24 - 24MHz Cortex-M0+ 4KB MCU | Silicon Labs
料号： EFM32ZG110F4-QFN24 ✓ 量产中EFM32ZG110F4-QFN24 概述
A microcontroller is a programmable system-on-chip that combines a processor core, program memory, data memory, and peripherals such as timers, analog converters, and communication interfaces. The ARM Cortex-M0+ core provides a compact, energy-efficient architecture for embedded control, while the EFM32 Zero Gecko platform adds low-energy operating techniques, fast wake-up behavior, and energy-saving modes intended for battery-powered and duty-cycled products.
Key features of the EFM32ZG110F4-QFN24 include a 24 MHz Cortex-M0+ core, 4 KB of Flash, 2 KB of SRAM, and 17 digital I/O pins in a compact 24-QFN package. Its two 16-bit timers support periodic event generation, input capture, and basic output comparison, while the ADC allows analog sensor signals to be sampled without a separate converter. The listed AES hardware feature supports cryptographic workloads, although system-level security still depends on firmware, key handling, and peripheral configuration.
The 4 KB Flash and 2 KB RAM budget places this MCU in the entry-level Zero Gecko category. It is best suited to compact control nodes, simple sensing systems, and products that require deterministic peripheral handling but modest application code and data storage. Firmware size and stack requirements must be checked early, because only 2 KB of RAM leaves limited room for buffers, display structures, and protocol state.
Typical uses include IoT sensor nodes, low-power industrial monitors, compact wearable electronics, battery-operated accessories, and embedded control modules. The 5 mm by 5 mm QFN land pattern also supports space-constrained designs where the exposed pad and board-level thermal layout require careful assembly.
When designing the board, follow the manufacturer's recommended land pattern and provide the required decoupling capacitors close to the supply and ground pins. Confirm the available operating voltage, analog limits, and exact pin assignments in the manufacturer datasheet before layout release.
This page consolidates verified distributor availability, manufacturer specifications, same-package drop-in candidates, and design considerations that help engineers evaluate the EFM32ZG110F4-QFN24 beyond a basic distributor parameter listing.

典型应用
EFM32ZG110F4-QFN24 适用于 6 应用s: Battery-Powered IoT Sensor Nodes, Compact Industrial Monitoring, Low-Power Wearable Electronics, Smart Home Sensor and Control Module, Battery-Operated Accessory Controls, Embedded Security and Access-Control Module.
Battery-Powered IoT Sensor Nodes
The EFM32ZG110F4-QFN24 fits periodic wireless sensor nodes because its ARM Cortex-M0+ core runs up to 24 MHz while the Zero Gecko platform provides fast wake-up behavior and energy-saving modes. The ADC samples analog sensor outputs, and the two 16-bit timers can support wake intervals or periodic measurements. Its 2 KB RAM is adequate for compact sensor buffering, but firmware must avoid large display or radio-state buffers.
推荐
Compact Industrial Monitoring
The EFM32ZG110F4-QFN24 is appropriate for compact industrial monitors that combine periodic analog measurement with local control. Its 24 MHz Cortex-M0+ core provides enough processing capability for filtering and event logic, while the ADC reduces the need for an external converter. The 17 digital I/O pins support switches, alarms, and status indicators, and the 24-QFN package simplifies dense control boards.
推荐
Low-Power Wearable Electronics
The EFM32ZG110F4-QFN24 suits wearable accessories and small embedded wearables where board area and energy consumption are tightly constrained. Its 5 mm by 5 mm QFN package leaves room for a sensor and battery, and the Zero Gecko low-energy modes support duty-cycled operation. The 4 KB Flash and 2 KB RAM require concise firmware, while the ADC can read analog sensor elements without a separate converter.
推荐
Smart Home Sensor and Control Module
The EFM32ZG110F4-QFN24 can act as the local controller in a small smart-home sensing module. The ADC handles variable analog outputs from environmental or presence sensors, while 17 digital I/O pins support actuators, status LEDs, and simple user inputs. Its 24 MHz Cortex-M0+ performance enables responsive local logic, and AES hardware acceleration assists selected encrypted communications, subject to correct key-management implementation in firmware.
推荐
Battery-Operated Accessory Controls
The EFM32ZG110F4-QFN24 is well suited to small battery-operated accessories that perform local button, motor, or lighting control. The two 16-bit timers can generate timing sequences, while the fast-wake-up behavior helps reduce the time the MCU remains active between user events. The compact QFN footprint supports space-constrained products, although the 2 KB RAM limit calls for minimal buffering and careful peripheral interrupt handling.
推荐
Embedded Security and Access-Control Module
The EFM32ZG110F4-QFN24 can support compact access-control and security modules that combine local sensing with authenticated communications. AES hardware acceleration provides a hardware path for supported cryptographic operations, and the 24 MHz core can process basic credential and event logic. Firmware designers must still implement key storage, authentication policy, and update procedures correctly, because the accelerator does not by itself create a secure product.

设计说明
Use the manufacturer QFN-24 land pattern and thermal-pad layout without substituting a generic 24-QFN footprint. Place the input and bulk decoupling capacitors close to their assigned supply and ground pins, and keep routing away from the exposed pad where electrical clearance allows. Because the exact pin numbers were not included in the verified snippets, derive every net from the official datasheet pin table rather than from a third-party symbol.
The MCU has only 2 KB of RAM and 4 KB of Flash, so power behavior should be evaluated together with firmware size. Avoid leaving unused peripherals clocked, disable unused GPIO pins, and select the lowest peripheral clock configuration that meets timing requirements. For battery-powered designs, measure sleep-mode current on a representative board because regulator efficiency, pull networks, and external sensors can dominate the MCU's own consumption.
Keep analog inputs away from fast digital edges and route them over a continuous ground reference. The ADC is useful for compact sensor interfaces, but accuracy depends on source impedance, acquisition time, filtering, and the reference network. If analog precision matters, follow the manufacturer's analog-layout guidance, include the recommended RC filtering, and consider separate analog and digital ground connections only where the datasheet explicitly supports that topology.
Do not assume that two Zero Gecko MCUs with the same speed, Flash size, and QFN package are automatically software- and pin-compatible. Before approving EFM32ZG108F4-QFN24 or EFM32ZG108F4-QFN24T as substitutes, compare the complete pin tables, power pins, debugger pins, boot configuration, peripheral instances, interrupt vectors, and device headers. Keep the original EFM32ZG110F4-QFN24 footprint if the PCB cannot accept a different peripheral mapping.
合规信息
The supplied verified snippets confirm RoHS and REACH are mentioned in comparison listings but do not provide a definitive status for the target device. AEC-Q100 is recorded as not applicable because this is a general-purpose MCU rather than an explicitly automotive-qualified part. No lead-free, halogen-free, or conflict-minerals declaration was provided.
