EFM32TG108F4-D-QFN24 - 32MHz Cortex-M3 4KB MCU | Silicon Labs
Silicon Labs EFM32TG108F4-D-QFN24 is an ARM Cortex-M3 microcontroller with a maximum clock speed of 32 MHz, 4 KB of Flash memory, 2 KB of RAM, and 17 digital I/O pins, housed in a 24-QFN package measuring 5 mm by 5 mm. It belongs to the EFM32 Tiny Gecko family and is designed for compact, energy-sensitive embedded systems that require efficient processing, low-power operation, and rapid wake-up behavior.
An EFM32 microcontroller is a 32-bit embedded processing IC that combines an ARM Cortex-M processor core with flash memory, RAM, general-purpose I/O, timers, communications peripherals, and low-energy management features. Within the product hierarchy, this device is an MCU, embedded controller, semiconductor, and energy-conscious alternative to more general-purpose microcontroller platforms when compact size and low standby consumption are important design priorities.
The verified device data identifies an ARM Cortex-M3 core operating up to 32 MHz, 4 KB of programmable Flash organized as 4K by 8, 2 KB of SRAM, and 17 digital I/O pins. It also includes two 16-bit timers. Its small 5 mm by 5 mm QFN-24 land pattern supports dense PCB construction, while the 24-QFN package provides a practical surface-mount option for wearable, sensor, embedded-control, and connected peripheral designs.
The Tiny Gecko architecture emphasizes energy-saving operating modes, fast wake-up times, and retention-oriented low-energy techniques. These characteristics are particularly valuable in battery-operated equipment where the controller may spend most of its time asleep and briefly process sensor readings, control outputs, or exchange data. The Cortex-M3 processor provides a substantially more capable instruction set than an 8-bit controller while retaining a compact, cost-conscious embedded footprint.
Typical uses include low-power sensor nodes, compact industrial sensing modules, battery-powered accessories, wearable-device subcontrollers, building-control endpoints, and small instrumentation products. In these applications, the 4 KB Flash and 2 KB RAM favor firmware focused on control logic, sampling, local signal conditioning, and communications support rather than large graphical interfaces or extensive local data storage.
Designers should verify the complete exposed-pad connection, pin multiplexing, decoupling requirements, programming interface, and operating limits against the manufacturer datasheet before layout release. The verified snippets provide the principal electrical and package information, but they do not expose the complete QFN-24 pin table or all timing and peripheral details, so unsupported values are not inferred in this data set.
This page combines verified manufacturer and distributor specifications with package and lifecycle context, a strictly filtered replacement analysis, and engineering-oriented application guidance. It distinguishes confirmed parameters from missing details, making it more useful for preliminary design decisions and procurement than a distributor listing alone.
