部品番号: EFM32TG232F16-QFP64 ✓ 生産中EFM32TG232F16-QFP64 概要
A microcontroller is the central programmable element of an embedded system, integrating a CPU core, nonvolatile program memory, volatile data memory, peripherals, and I/O into one semiconductor package. The ARM Cortex-M3 provides a 32-bit RISC processing architecture, while the Tiny Gecko platform adds low-energy features suited to battery-powered sensors, industrial equipment, consumer controls, and connected products. This device operates from a 1.85 V to 3.8 V supply range.
The EFM32TG232F16-QFP64 combines 16 kB Flash, 4 kB RAM, 53 digital I/O pins, and two 16-bit timers in one package. Its 32 MHz maximum CPU speed provides adequate processing performance for protocol handling, data acquisition, local control, and low-complexity user interfaces. The 10 mm by 10 mm TQFP package also exposes 53 digital I/O pins, supporting simultaneous peripheral connections while remaining compatible with conventional surface-mount assembly.
Its energy-conscious architecture is the principal technical advantage. The Tiny Gecko family supports energy-saving modes and fast wake-up times, allowing firmware to remain responsive without continuously running the CPU at full clock speed. Applications can therefore balance computational throughput against standby consumption according to the duty cycle of the product.
Typical uses include low-power sensor nodes, compact industrial controllers, wearable accessories, meter-management electronics, battery-operated monitoring equipment, and embedded control modules. The combination of Cortex-M3 processing, flexible GPIO, and low-power operation is particularly useful when a design must fit multiple digital interfaces into a limited board area without adding a separate low-power controller.
Designers should plan the PCB for the 64-pin TQFP footprint, preserve adequate clearance around adjacent leads, and route high-frequency or sensitive analog signals away from switching nodes. Firmware should use the low-energy modes only after validating wake-up sources, clock transitions, and peripheral states. Component compatibility requires checking the complete Silicon Labs pinout and peripheral table before substituting another EFM32 device.
This product page consolidates the key electrical, memory, package, and low-power characteristics with practical implementation guidance. It also distinguishes verified same-footprint alternatives from functionally similar devices, helping engineers evaluate replacement options without treating a different microcontroller family as a true drop-in substitute.

主な用途
EFM32TG232F16-QFP64 の用途: 6 件s: Low-Power Wireless Sensor Node, Industrial Condition Monitoring, Battery-Powered Metering Device, Embedded Control and HMI Module, Portable Medical Accessory, Secure Network Edge Device.
Low-Power Wireless Sensor Node
The EFM32TG232F16-QFP64 fits compact wireless sensor nodes that periodically measure a physical quantity and transmit the result through a short-range radio. Its 32 MHz ARM Cortex-M3 core can service sensor conversion, packet preparation, and radio-control logic, while the Tiny Gecko low-energy modes allow the controller to sleep between events. Sixteen kilobytes of Flash and 4 kB of RAM support compact protocol stacks and data buffering, although code-size headroom must be checked before committing a radio library. The 53 digital I/O pins provide flexible connections to sensors and status indicators without requiring a large I/O expander.
おすすめ
Industrial Condition Monitoring
For industrial condition monitoring, the EFM32TG232F16-QFP64 can acquire periodic measurements from equipment and apply filtering, threshold checks, or event logic before transmitting results. Its two 16-bit timers support timing-intensive input capture, output compare, or periodic sampling tasks, while 53 digital I/O pins support discrete inputs, fault signals, and local alarms. A 1.85 V to 3.8 V operating range permits integration with 2.5 V and 3.3 V sensor networks. The small 10 mm TQFP footprint leaves board space for isolation, signal conditioning, and communication hardware.
おすすめ
Battery-Powered Metering Device
The EFM32TG232F16-QFP64 is well suited to compact metering devices that must conserve energy while maintaining deterministic timing. Its low-energy operating modes support long idle periods, and fast wake-up behavior allows the processor to respond to scheduled tasks or external interrupts without continuous full-speed operation. The 32 MHz Cortex-M3 core can calculate totals, format readings, and manage communication, while two 16-bit timers provide the timing basis for measurement intervals. The 16 kB Flash and 4 kB RAM favor compact protocols and modest local data storage.
おすすめ
Embedded Control and HMI Module
The EFM32TG232F16-QFP64 can act as the local controller for compact keypads, status displays, relays, and communication interfaces. Its 53 digital I/O pins provide substantial parallel-control capacity, reducing the need for chained I/O expanders in space-constrained products. The two 16-bit timers can handle display refresh, debouncing, pulse measurement, or periodic service tasks, while the Cortex-M3 processor manages a simple graphical or menu-driven interface. Its 64-pin TQFP package is suitable for cost-driven PCB assembly when compared with a fine-pitch BGA package.
おすすめ
Portable Medical Accessory
The EFM32TG232F16-QFP64 can serve as the control core in a portable medical accessory that handles buttons, indicators, and low-bandwidth sensor data while relying on a battery. Its low-energy architecture supports duty-cycled operation, and the 53 digital I/O pins leave capacity for sensor-enable signals, status LEDs, and interface control. The 32 MHz processor is sufficient for basic filtering and device-state management rather than intensive signal analysis. Medical use still requires separate evaluation of electrical isolation, regulatory quality, calibration, and any application-specific safety requirements.
おすすめ
Secure Network Edge Device
The EFM32TG232F16-QFP64 is appropriate for a small network-edge device that terminates a local serial interface and forwards status or control commands. Its 53 GPIO pins can support UART, SPI, I2C, interrupts, and discrete control signals, while 4 kB RAM accommodates short protocol frames and task state. AES capability is listed for the MCU family, although the final firmware security design must address key storage, peripheral configuration, and update procedures. The 16 kB Flash budget favors a focused firmware image with minimal library overhead.

選定ガイド
Do not choose this MCU when firmware or data-buffer requirements exceed the 16 kB Flash and 4 kB RAM limits, or when the board requires a different footprint, voltage tolerance, or high-speed external-memory interface. Another Cortex-M3 device may offer similar CPU performance, but cross-brand substitution generally requires schematic changes, peripheral reassignment, a new startup configuration, and firmware porting. For a fresh design, confirm the final code size, active peripherals, wake-up behavior, and PCB footprint before placing a production order.

設計ノート
Assign the 64-pin TQFP footprint directly from the Silicon Labs package drawing and verify lead dimensions against the PCB library before fabrication. Place the device where the thermal and decoupling connections remain short, and check clearance to tall or moving enclosure parts. Because 53 pins are user digital I/O, create a pin-assignment matrix in the schematic before routing so alternate-function conflicts are detected before PCB layout.
Design the 1.85 V to 3.8 V supply rail for both active current and transient demand from enabled peripherals. Place local bulk and high-frequency decoupling at the MCU supply pins using the capacitance and placement guidance in the manufacturer datasheet. Confirm that 2.5 V and 3.3 V peripheral buses cannot create overshoot beyond the MCU limits, especially during reset or peripheral shutdown.
Do not select a replacement from clock speed and package dimensions alone. EFM32 devices require compatibility in supply pins, ground pins, boot configuration, peripheral mappings, interrupt assignments, and firmware support. Confirm the complete pin description table and startup configuration for EFM32TG232F16-D-QFP64, and perform a firmware and board-level regression test before using it as a drop-in substitute.
Use the Tiny Gecko low-energy modes to meet the product energy budget, but validate wake-up behavior with every peripheral and interrupt source enabled. Measure current across active, idle, sleep, and deep-sleep states at the intended supply voltage. Sensor leakage, pull resistors, indicator LEDs, and communication modules can exceed the MCU contribution, so isolate those loads or switch them off when the device is dormant.
