N.º da peça: EFM32G200F16-QFN32 ✗ Fim de vidaEFM32G200F16-QFN32 Visão geral
A microcontroller is a programmable semiconductor that integrates a processor core, memory, peripherals, and I/O into one device. The EFM32G200 belongs to the EFM32 Gecko family, a low-power platform designed around an ARM Cortex-M3 core. Its 32-bit processing supports responsive control logic while the 16 kB Flash configuration provides embedded program storage and the 8 kB RAM provides working memory for protocol handling, state management, and control tasks.
Key features include a maximum operating speed of 32 MHz, 24 digital I/O pins, two 16-bit timers, internal oscillator options, and low-power platform features. The 32-QFN exposed-pad package supports compact PCB layouts, while the exposed thermal pad provides a thermal connection to the board and helps transfer heat from the device. The operating temperature range is -40 °C to 85 °C, making the device appropriate for industrial and embedded environments within that range.
The EFM32G200 architecture is designed for applications where energy efficiency and rapid response are more important than maximum flash capacity. Its Cortex-M3 processor, Wake-up Interrupt Controller, timer resources, and low-energy modes provide a practical platform for battery-powered sensors, portable instrumentation, building automation, and small industrial control modules. The 24 I/O pins provide connectivity for sensors, switches, indicators, communication interfaces, and external control signals.
Typical designs place the microcontroller near the system’s sensor and power-conversion sections, with decoupling capacitors at the supply pins and the exposed pad connected to a suitable ground-plane area. Firmware should use the manufacturer’s low-power configuration procedures, validate wake-up behavior under the required operating conditions, and confirm peripheral pin multiplexing before PCB release. This page combines verified manufacturer and distributor information with package, pricing, sourcing, and replacement guidance for engineers evaluating the EFM32G200F16-QFN32.

Aplicações típicas
EFM32G200F16-QFN32 é adequado para 6 aplicaçãos: Battery-Powered Sensor Nodes, Industrial Control Modules, Building Automation Controllers, Portable Measurement Instruments, Smart Home Hubs, LED Lighting Controllers.
Battery-Powered Sensor Nodes
The EFM32G200F16-QFN32 fits compact sensor nodes that periodically measure a physical condition, process the result locally, and return to a low-energy state. Its ARM Cortex-M3 core operates up to 32 MHz, allowing sampling, filtering, and local decision-making without a higher-power processor, while the low-power platform provides fast wake-up behavior and energy-saving modes. The 24 digital I/O pins can support sensors, interrupts, indicators, and configuration switches, and the 8 kB RAM is suitable for compact buffers. The key design trade-off is the 16 kB Flash limit, which makes code-size planning essential for wireless stacks or complex calibration logic.
Recomendado
Industrial Control Modules
The EFM32G200F16-QFN32 is suitable for small industrial control modules operating between -40 °C and 85 °C. Its 32 MHz Cortex-M3 core provides responsive digital control, two 16-bit timers support repetitive timing or event capture, and 24 I/O pins offer connections to sensors, relays, indicators, and field inputs. The 1.98 V to 3.8 V operating range enables integration with low-voltage industrial rails when appropriate regulation is available. Because the MCU is identified as discontinued in one cross-reference source, engineers should verify lifecycle status and secure supply before committing to a new long-life industrial design.
Recomendado
Building Automation Controllers
The EFM32G200F16-QFN32 can serve as the local controller in a building-automation subsystem handling occupancy inputs, lighting control, alarms, and scheduled actuator commands. Its 24 digital I/O pins reduce the need for external I/O expanders, while the two 16-bit timers and 32 MHz Cortex-M3 performance accommodate event timing and control logic. Low-energy operation is valuable in systems that remain connected to building power but operate mostly idle. The primary constraint is software capacity: 16 kB Flash and 8 kB RAM require disciplined modular code, and a larger-memory variant is preferable if the design includes extensive protocol libraries.
Recomendado
Portable Measurement Instruments
The EFM32G200F16-QFN32 supports portable measurement instruments that combine local signal conditioning, digital control, and user I/O. The verified comparison identifies a 4 x 12-bit ADC and 1 x 12-bit DAC configuration for this device, enabling basic mixed-signal acquisition and control without requiring the largest embedded system. The 24 digital I/O pins support display controls, switches, status indicators, and external interfaces, while the compact 6 x 6 mm QFN package supports portable PCB layouts. Designers should budget Flash for calibration tables and UI logic and should verify analog pin multiplexing in the manufacturer datasheet before layout release.
Recomendado
Smart Home Hubs
The EFM32G200F16-QFN32 can act as a compact smart-home endpoint for local switching, sensing, and wake-up response. Its fast-wakeup, low-power EFM32 platform is well matched to systems that remain idle for long periods and react to scheduled events or external interrupts. The 24 digital I/O pins can drive relays or monitor digital sensors, and the 32 MHz core handles lightweight state machines and communication handling. Because the MCU has only 16 kB Flash and no AES according to the verified Mouser listing, it is better suited to local endpoint control than to security-heavy gateway designs. External radios and secure elements may be required.
Recomendado
LED Lighting Controllers
The EFM32G200F16-QFN32 is appropriate for compact LED lighting controllers that need deterministic timing, local fault handling, and low standby consumption. Two 16-bit timers can support periodic timing tasks, while the 24 I/O pins provide control and status channels for LED drivers, buttons, and fault signals. The 32 MHz Cortex-M3 core is more than adequate for closed-loop dimming or simple sequencing logic. The designer should use the manufacturer’s low-power and clock configuration guidance and verify the exposed-pad thermal layout because enclosed LED fixtures can restrict convection. A memory-expanded variant is useful if the controller also implements communications and field-update logic.

Notas de projeto
Use the official 32-QFN 6 x 6 mm land pattern and verify pad, solder-mask, and paste dimensions against the current package drawing. Place input and output decoupling capacitors close to their respective supply pins, connect the exposed pad to the appropriate ground plane with the manufacturer-recommended via pattern, and avoid thermal-coupling paths to sensitive analog components. The exposed pad is part of the thermal and electrical design, not a mechanical feature that can be omitted.
The device operates across 1.98 V to 3.8 V, but the allowed range does not remove the need to design for sequencing, startup, and transient conditions. Confirm which supply pins and internal blocks are operational during startup, use stable local regulation for sensitive analog rails, and validate brownout behavior in the completed board. The 2.5 V and 3.3 V operating associations in the supplied comparison data do not replace the detailed electrical-limit and power-up requirements in the official datasheet.
Do not treat the same 32-QFN outline as proof that every EFM32 variant is a drop-in replacement. Although all five listed alternatives use the 32-QFN 6 x 6 mm package, boot pins, power pins, peripheral mappings, exposed-pad usage, and reset behavior can differ by family. Before substitution, compare the official pin tables and confirm that the new device's startup, clock, debugger, and firmware requirements are compatible with the existing PCB and software.
Estimate junction temperature from actual regulator dissipation and the board-specific thermal resistance rather than relying on a generic package rating. The exposed pad can lower junction temperature when connected to a substantial copper area and thermal vias, but its effectiveness depends on airflow, board size, adjacent heat sources, and the maximum ambient temperature. Verify operation at -40 °C to 85 °C, including the temperature rise of surrounding power components, before release.
Informações de conformidade
The supplied verified results do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not applicable because the EFM32G200F16-QFN32 is an industrial and embedded microcontroller rather than an identified automotive-qualified device.
