EFM32TG110F8-D-QFN24

EFM32TG110F8-D-QFN24 - 32MHz Cortex-M3 Tiny Gecko MCU | Silicon Labs

The Silicon Labs EFM32TG110F8-D-QFN24 is an ARM Cortex-M3 32-bit microcontroller running up to 32 MHz with 8 KB of Flash and 2 kB of RAM, housed in a 24-QFN (5 x 5 mm) surface-mount package. It is built on Silicon Labs' energy-friendly EFM32 platform, combining a low-power architecture with fast wake-up from energy-saving modes for battery-operated and energy-harvesting designs. A microcontroller (MCU) is a single integrated circuit that contains a processor core, program memory, data memory and a set of dedicated peripherals such as timers, GPIO, serial interfaces and analog blocks. Within the component hierarchy, the EFM32TG110 sits in the ARM Cortex-M3 class of 32-bit embedded processors and in the EFM32 Tiny Gecko family of Silicon Labs low-power MCUs, a line positioned between the larger EFM32 Gecko and the ultra-low-power EFM32 Zero Gecko families for designs where energy cost per data point matters. Key features of this device include an ARM Cortex-M3 core operating up to 32 MHz, 8 KB of Flash program memory organized as 8K x 8, 2 kB of SRAM, 17 digital I/O pins and two 16-bit timers. Silicon Labs specifies run-mode current of 150 uA/MHz and stop-mode current as low as 0.6 uA, which is the core reason the family is popular in coin-cell and sensor-node products. The device also integrates an AES hardware accelerator, analog peripherals including an operational amplifier, and a 2-pin serial-wire debug interface with a separate 1-wire Serial Wire Viewer pin for profiling and trace output. Technically, the Tiny Gecko platform gives the EFM32TG110 fast wake-up times from its deep-sleep states, retention of output state in shutoff mode, and a peripheral set that can operate autonomously. This lets a design sleep at microamp current, wake, sample a sensor, transmit a short packet and return to sleep without the long wake latency typical of generic low-power MCUs, which directly reduces average current in duty-cycled nodes. Typical applications include wireless sensor nodes and IoT end devices, industrial monitoring and metering, battery-powered handheld instruments, energy-harvesting sensors, smart home accessories and small motor or actuator control sub-systems where a full MCU plus glue logic would be over-specified. When designing with the EFM32TG110F8-D-QFN24, remember that its 2 kB of RAM is the real design constraint: keep stack depth, DMA buffers and protocol buffers lean, and prefer the 8 KB Flash part only for code sizes that genuinely fit. Route the two SWD debug pins to test points so the board can be programmed and profiled in production. This page consolidates device specifications, drop-in alternatives in the same 24-QFN footprint, a parameter-by-parameter comparison, and practical low-power design notes so engineers can qualify the part against a second source and plan a board layout in one pass.

The principal design consideration is the small memory footprint. Firmware must fit within 8 kB of Flash and its working data within 2 kB of RAM, so code size, library use, stack depth, and interrupt handling should be checked early. Hardware design should follow Silicon Labs guidance in AN0002 EFM32 Hardware Design Considerations. This page consolidates verified manufacturer and distributor details, package information, application guidance, and selection considerations. It helps engineers compare the EFM32TG110F8-QFN24 against available alternatives without treating merely similar microcontrollers as verified drop-in replacements.

Two 16-bit timers support periodic timing, input capture, output compare, and basic motor or control functions. Integrated AES hardware accelerates cryptographic operations, while the three operational amplifiers reduce the need for external analog signal-conditioning components in suitable low-power measurement circuits. The 1.85 V to 3.8 V operating range permits use from 2 V-class and 3.3 V systems when the individual rail, peripheral, and timing requirements remain within device limits. The 24-QFN 5 x 5 mm package provides a compact surface-mount option for space-constrained products. Because the QFN has no exposed leads, PCB layout must provide adequate solderable land area and careful thermal-via placement beneath the package where appropriate. Typical applications include low-power sensor nodes, compact industrial control modules, battery-operated accessories, small motor-control systems, and embedded instrumentation. The ARM Cortex-M3 architecture provides a familiar software ecosystem, while the 8 kB Flash footprint makes the MCU most appropriate for compact control logic rather than resource-intensive applications. The 2 kB RAM also favors targeted buffering and state management over large data acquisition workloads. Designers should allocate decoupling capacitors close to the supply pins, confirm that every exposed-pad thermal and solder-layout requirement follows the package drawing, and keep analog signals away from fast-switching nodes. The three operational amplifiers and 17 I/O pins should be assigned only after checking the pin-mux limitations, analog operating ranges, and shared peripheral resources in the manufacturer pin description table. This product page consolidates the core MCU specifications, package constraints, application guidance, and validated cross-reference options into one engineering-focused reference. It also highlights memory differences and family considerations that determine whether a candidate can replace the EFM32TG110F8-QFN24T without PCB or firmware redesign.

EFM32TG210F8-D-QFN32 - 32MHz ARM Cortex-M3 MCU | Silicon Labs

The Silicon Labs EFM32TG210F8-D-QFN32 is a 32-bit ARM Cortex-M3 microcontroller with a 32 MHz maximum clock, 8 kB of Flash memory, 2 kB of RAM, and 24 digital I/O pins in a 32-pin QFN package with an exposed pad. It combines a compact memory footprint with energy-saving modes and fast wake-up behavior for embedded systems that prioritize low power. An EFM32 microcontroller is an embedded processor platform that integrates a CPU, memory, analog and digital peripherals, interrupt control, and energy-management functions into one device. The EFM32TG210 belongs to the Tiny Gecko family, where the ARM Cortex-M3 processor operates within a system designed for both performance-sensitive control and low-current standby operation. This hierarchy places the device among 32-bit microcontrollers, embedded processors, and general-purpose semiconductor components. The Tiny Gecko architecture operates at up to 32 MHz and includes two 16-bit timers, digital I/O, AES hardware support, and an operational amplifier according to the product listing. Energy-sensitive operation is supported by consumption as low as 0.6 µA in Stop mode and approximately 150 µA/MHz in Run mode. These characteristics make the controller useful in battery-operated products where duty-cycled sensing and measurement must coexist with responsive control firmware. The EFM32TG210F8-D-QFN32 uses 8 kB Flash for program storage and 2 kB RAM for working data. Its integrated analog features can reduce the need for external signal-conditioning components in compact sensor nodes, while the 24 digital I/O pins support switches, indicators, communications, and external control signals. The exposed-pad QFN construction also provides a thermal path through PCB copper, making package layout an important part of reliable operation. Typical uses include connected sensor nodes, compact industrial monitors, wearable accessories, low-power measurement instruments, and consumer products that wake briefly to acquire or transmit data. In these systems, the MCU acts as the central controller: it samples inputs, executes embedded algorithms, manages timers, controls peripherals, and returns to a low-energy state whenever the measurement cycle is complete. Designers should follow the manufacturer pin-description table when assigning every QFN signal and must preserve the exposed-pad connection to the appropriate PCB plane. Place decoupling capacitors close to the supply pins, confirm oscillator and reset requirements in the device datasheet, and calculate the duty-cycle-dependent average current before selecting the power source. This page combines the core device specifications, engineering comparisons, application guidance, and practical design notes needed to evaluate the EFM32TG210F8-D-QFN32.

The official product description also identifies low-energy techniques, fast wake-up behavior, and energy-saving modes. These characteristics suit systems that spend substantial time between active operations while retaining deterministic access to embedded peripherals. The device belongs to Silicon Labs' Tiny Gecko family and provides an integrated AES and operational-amplifier feature set according to distributor product data. Its 1.85 V to 3.8 V operating range allows use in low-voltage embedded designs, while the 32-QFN 6x6 mm package supports compact PCB layouts. Exact peripheral availability, electrical limits, pin functions, and tool-support details should be confirmed against the manufacturer documentation before production design release. Typical applications include battery-powered sensing, compact industrial controllers, wearable or accessory electronics, low-power embedded nodes, and portable instruments. In these systems, the MCU can execute firmware, operate timers, read inputs, and control outputs while using its low-power platform to reduce activity outside the required measurement or control intervals. Designers should verify the QFN land pattern, exposed-pad connection, pin multiplexing, decoupling requirements, and supported voltage range in the manufacturer documentation. The 6x6 mm QFN package also requires careful PCB layout and assembly process control to achieve reliable thermal and electrical performance.
