EFM32TG230F8-QFN64 Overview
A microcontroller is a programmable semiconductor that integrates a CPU core, memory, peripherals, and I/O into one device. The EFM32TG230 belongs to the Tiny Gecko family and is positioned between simple 8-bit controllers and higher-resource 32-bit embedded processors. Its Cortex-M3 architecture supports interrupt-driven control, while the integrated Flash, RAM, timers, communication interfaces, and analog peripherals reduce the need for external components.
Verified manufacturer and distributor data identifies a 32-bit ARM Cortex-M3 core, 32 MHz maximum speed, 8 KB Flash, 2 KB RAM, 56 digital I/O pins, and two 16-bit timers. The device is suited to energy-sensitive applications that require compact embedded control, low-power operation, and moderate processing performance. Its 64-QFN package also provides a dense land pattern for space-constrained PCB designs.
The manufacturer describes the Tiny Gecko platform as using innovative low-energy techniques, fast wake-up times, and energy-saving modes. These characteristics matter in systems that spend substantial time sleeping, such as portable instruments, connected sensors, industrial monitoring nodes, and low-power embedded products. The exact current, voltage, memory, peripheral, environmental, and compliance values not present in the supplied verified data are not inferred here.
Typical applications include low-power sensor nodes, industrial monitoring equipment, compact control systems, connected embedded products, and battery-operated devices. Firmware can use the Cortex-M3 interrupt architecture and timers for deterministic control, while low-power modes help reduce energy use between measurement or communication events.
Designers should verify the complete electrical limits, pin multiplexing, exposed-pad requirements, decoupling requirements, and firmware-support status against the official Silicon Labs documentation before layout or production release. The supplied sources provide a manufacturer product page, manufacturer-linked technical documentation, and distributor records, but do not provide a complete verified pinout or lifecycle statement.
This page consolidates the supplied manufacturer and distributor records, separates verified facts from unavailable data, and adds practical selection and sourcing guidance for engineers evaluating the EFM32TG230F8-QFN64.

Typical Applications
EFM32TG230F8-QFN64 is suitable for 6 applications: Low-Power Sensor Nodes, Industrial Monitoring Equipment, Battery-Operated Portable Controls, Compact Embedded Control Systems, Connected Energy-Sensitive Devices, Small Measurement Instruments.
Low-Power Sensor Nodes
The EFM32TG230F8-QFN64 fits compact sensor nodes that periodically measure a physical quantity, process the result locally, and return to a low-power state between events. Its ARM Cortex-M3 core operates up to 32 MHz for handling control logic and short communication bursts, while 2 KB of RAM and 8 KB of Flash support small embedded firmware. Silicon Labs specifically identifies fast wake-up and energy-saving modes as platform benefits, making the device relevant for battery-operated environmental or condition-monitoring products. The design must still confirm the exact sleep currents, wake-up timing, and peripheral behavior in the complete datasheet.
Recommended
Industrial Monitoring Equipment
The EFM32TG230F8-QFN64 is appropriate for industrial monitoring modules that combine digital inputs, periodic sensing, status indication, and a serial communications link. Its 56 digital I/O pins provide substantial interface capacity for discrete sensors, alarms, and control signals in a compact 9 x 9 mm QFN footprint. The 32 MHz Cortex-M3 core can execute protocol and control tasks while the Tiny Gecko energy-saving modes help manage duty-cycled operation. Industrial qualification details, extended temperature limits, isolation, and EMC requirements are not included in the supplied data and must be verified separately.
Recommended
Battery-Operated Portable Controls
A portable control product can use the EFM32TG230F8-QFN64 for local button handling, actuator timing, status sequencing, and low-duty-cycle logic without requiring a larger processor. Its 8 KB Flash and 2 KB RAM are appropriate for focused firmware rather than large graphical or application-heavy workloads. The 56-pin I/O count also allows the controller to integrate multiple inputs and outputs while preserving a compact board outline. Designers should account for regulator efficiency, battery chemistry, sleep-mode leakage, and the device’s verified current limits rather than assuming the low-power positioning alone determines runtime.
Recommended
Compact Embedded Control Systems
The EFM32TG230F8-QFN64 can serve as the central controller in a small embedded system that coordinates timers, digital signals, communications, and simple peripheral functions. Its 32-bit ARM Cortex-M3 architecture provides a familiar interrupt-driven control platform, and the verified 56 digital I/O pins allow the design to avoid adding a separate large I/O expander when the pin budget fits. The 64-QFN package supports dense layouts, but exposed-pad and assembly details must be confirmed from the manufacturer documentation before production layout release.
Recommended
Connected Energy-Sensitive Devices
For connected devices that transmit data intermittently, the EFM32TG230F8-QFN64 combines a 32 MHz Cortex-M3 core with low-power platform features described by Silicon Labs. Firmware can process a sensor reading, update a local output, perform a short communications transaction, and then enter an energy-saving mode. This pattern suits small gateways, remote controls, and instrumentation nodes where a higher-power MCU would increase idle consumption. The supplied data does not verify radio functionality, so external communication hardware and its power budget must be evaluated as part of the complete system.
Recommended
Small Measurement Instruments
The EFM32TG230F8-QFN64 can support small measurement instruments that need deterministic timer support, digital control, and local signal conditioning. The two verified 16-bit timers provide useful resources for periodic sampling, pulse timing, or control-loop tasks, while the 56 digital I/O pins can connect sensors, switches, displays, and status indicators. Its 1.85 V to 3.8 V listed supply range may simplify integration with compatible low-voltage analog and digital subsystems, although regulator selection and signal-level compatibility still require board-level validation.

Key Differentiators
- Compact low-power ARM Cortex-M3 platform (vs EFM32TG230F32-QFN64T)
- Verified 8 KB Flash and 2 KB RAM configuration (vs EFM32GG230F512-QFN64)
- 56 digital I/O pins in a compact package (vs EFM32TG840F8-QFN64T)
- Two 16-bit timers for embedded timing tasks (vs EFM32GG230F1024G-E-QFN64)
Design Notes
Validate the complete power architecture before layout. The supplied distributor data lists a 1.85 V to 3.8 V supply range, but it does not provide core, I/O, sleep, or active current limits. Select a regulator with adequate startup, transient, and noise margin for the MCU and any connected analog circuitry. Use the manufacturer’s recommended decoupling and power-entry guidance when those values are available.
Confirm the 64-QFN land pattern, exposed-pad treatment, pin-one orientation, and assembly requirements from the official package drawing. A 9 x 9 mm QFN can be compact but leaves little room for routing errors around the perimeter and thermal pad. Preserve the manufacturer’s recommended via pattern and solder-mask requirements, and review the PCB against the current Silicon Labs hardware-design guidance before fabrication.
Do not treat related EFM32 MPNs as drop-in replacements without checking the complete datasheet. The alternatives listed here share a QFN64 family context, but the supplied cross-reference results do not verify pin multiplexing, alternate functions, memory limits, peripheral availability, or lifecycle status. In particular, the T suffix and other ordering suffixes can affect packaging or qualification, so verify the manufacturer ordering table before substitution.
Compliance Information
The supplied verified web data does not explicitly state compliance status for the EFM32TG230F8-QFN64. Obtain current Silicon Labs product declarations or material compliance documentation before production release.
