EFM32G30F128-QFN64 - 32MHz Cortex-M3 128KB MCU | Silicon Labs
料号： EFM32G30F128-QFN64 ✓ 量产中EFM32G30F128-QFN64 概述
A microcontroller is a programmable semiconductor that combines a processor core, memory, and peripherals on one integrated circuit. The EFM32G30F128-QFN64 belongs to the Gecko family of 32-bit ARM Cortex-M3 microcontrollers, which sit within the hierarchy of embedded processors, microcontrollers, and semiconductor control devices. Its ARM Cortex-M3 core provides a 32-bit instruction set while the EFM32 peripheral architecture allows many hardware functions to operate with limited CPU involvement.
The verified device data identifies a maximum clock frequency of 32 MHz, 128 KB of flash organized as 128K x 8, and 16 KB of SRAM. Silicon Labs specifies a 1.98 V to 3.8 V operating supply range and a 64-QFN package measuring 9 x 9 mm. The family datasheet also reports low power consumption, including as little as 0.6 uA in Stop mode and 180 uA/MHz in Run mode, making the device suitable for battery-powered and energy-conscious products.
The Gecko architecture integrates high-speed analog and digital peripherals with the Cortex-M3 core. Product Revision E documentation identifies pin-compatible replacements for earlier EFM32G revision devices. However, firmware, peripheral configuration, and electrical behavior must still be checked against the specific part-number suffix before treating a related revision as a production substitute. A complete exposed-pad thermal design is essential because heat removal depends on the PCB copper area and thermal via arrangement.
Typical uses include industrial sensing and control nodes, compact environmental monitors, battery-powered IoT endpoints, wearable accessories, and connected measurement instruments. The small 9 x 9 mm QFN footprint supports space-constrained designs where a larger quad flat package would be undesirable. The 128 KB flash capacity provides room for application firmware, protocol stacks, and boot code, while the 16 KB RAM supports task working memory and moderate buffering.
Designers should follow the manufacturer's recommended power, decoupling, and exposed-pad land-pattern requirements. A high-quality local ground plane and short return paths help analog and digital sections remain stable under switching loads. Confirm the exact operating temperature grade, peripheral mix, and pin multiplexing for the ordered MPN before layout release because the verified distributor data does not specify those complete values.
This page consolidates verified manufacturer specifications, distributor availability information, pin-compatible same-family options, package constraints, and practical engineering guidance. The comparison material also distinguishes genuine drop-in choices from related devices that require firmware or board-level qualification.

典型应用
EFM32G30F128-QFN64 适用于 6 应用s: Battery-Powered IoT Sensor Nodes, Industrial Sensing and Control, Environmental Monitoring Instruments, Connected Wearable Accessories, Instrumentation and Measurement Products, Low-Power Data Acquisition.
Battery-Powered IoT Sensor Nodes
The EFM32G30F128-QFN64 fits compact battery-powered sensor nodes because its Gecko family can consume as little as 0.6 uA in Stop mode and 180 uA/MHz in Run mode. The 32 MHz Cortex-M3 core handles local sampling and protocol preparation, while 128 KB of flash accommodates application code and 16 KB of RAM supports working buffers. A 9 x 9 mm QFN also conserves board area in wearable and distributed sensing products. Design care should focus on duty cycling, analog-sensor settling time, and avoiding peripheral operation during the longest sleep interval.
推荐
Industrial Sensing and Control
The EFM32G30F128-QFN64 is suitable for industrial sensing and control nodes that need deterministic 32-bit processing in a compact package. Its 128 KB flash provides space for control firmware and communications protocols, while the 16 KB RAM supports moderate data acquisition and buffering. The 64-QFN 9 x 9 mm footprint is useful where a larger plastic package would complicate panel placement. For factory equipment, confirm the exact temperature grade and peripheral requirements because those details were not present in the verified retailer data.
推荐
Environmental Monitoring Instruments
The EFM32G30F128-QFN64 can act as the control processor in an environmental monitor that combines temperature, humidity, gas, or light sensing with local data processing. Its 32 MHz Cortex-M3 performance supports sampling control and filtering, and the Gecko family's autonomous peripherals reduce the need for continuous CPU intervention. Low Stop-mode current is particularly valuable when measurements occur at intervals rather than continuously. The 1.98 V to 3.8 V supply range also allows careful selection of the sensor and regulator rails.
推荐
Connected Wearable Accessories
The EFM32G30F128-QFN64 suits compact wearable accessories that require more processing than a simple sensor but cannot accept a large package. Its 64-QFN 9 x 9 mm footprint preserves PCB area for radios, sensors, and batteries, while 128 KB of flash supports feature-rich firmware. The family-level 0.6 uA Stop-mode figure supports duty-cycled operation, although display, radio, and motion-sensor loads will dominate the final power budget. Firmware must confirm peripheral pin multiplexing and sleep-mode entry before the layout is finalized.
推荐
Instrumentation and Measurement Products
The EFM32G30F128-QFN64 is appropriate for compact instrumentation that performs acquisition control, calibration, and local user-interface management. Its 32-bit Cortex-M3 core handles fixed-point and control algorithms, and the Gecko family's integrated analog capabilities are useful in signal-chain designs. The 16 KB RAM is adequate for moderate buffering but may require external memory for waveform capture or large protocol stacks. Careful exposed-pad thermal layout and local decoupling are necessary to preserve measurement stability and avoid added noise.
推荐
Low-Power Data Acquisition
The EFM32G30F128-QFN64 works well in low-power data-acquisition systems that periodically enable sensors, collect values, and transmit results. Its 180 uA/MHz family-level run figure makes the 32 MHz processing capability useful for short active bursts, and Stop-mode current as low as 0.6 uA supports long inactive periods. The 128 KB flash can hold buffering logic and correction algorithms, while 16 KB of RAM handles modest sample batches. Success depends on using the EFM32 low-power modes and selecting a regulator with very low quiescent current.

设计说明
The 64-QFN package uses an exposed pad that is central to heat removal. Provide the land pattern specified by Silicon Labs and connect the pad to a low-impedance ground plane using multiple thermal vias rather than a single narrow connection. Estimated: if the design dissipates 0.5 W and the completed PCB has a junction-to-ambient rise of 45 C, the junction temperature would be approximately ambient plus 22.5 C; this is an engineering estimate, not a manufacturer limit.
Place the supply bypass capacitor directly across the closest VDD and ground pins, keeping the loop short and within the manufacturer's layout guidance. Select a regulator with low quiescent current because the family can reach 0.6 uA in Stop mode; a regulator drawing more than the load can erase the benefit of sleep-mode operation. Verify brownout, startup, and load-transient behavior across the complete 1.98 V to 3.8 V operating range.
Keep analog inputs, sensor references, and the MCU power ground in a compact, quiet return region. Route high-current loads and switching-node connections away from exposed-pad and precision-signal areas. Because the verified data confirms a compact 9 x 9 mm QFN rather than a leaded package, inspect the assembled board for solder bridging, voiding under the exposed pad, and adequate fill around closely spaced QFN leads before environmental testing.
Do not treat an EFM32G30F128 suffix match as proof of complete interchangeability. Revision, temperature grade, green status, peripheral population, and firmware support can affect the orderable configuration. Use the Silicon Labs EFM32G data sheet, Reference Manual, Revision E product-change notice, and current errata together. In particular, confirm exposed-pad connections, startup pins, analog references, and peripheral pin multiplexing before releasing a substitute PCB.
合规信息
The verified web data does not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status for this orderable MPN. The G-E suffix identifies the green configuration for EFM32G30F128G-E-QFN64, but this does not by itself establish every requested compliance declaration. Consult the current Silicon Labs product declaration and material-compliance documentation for the ordered suffix.
