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.

EFM32TG110F8-QFN24T

EFM32TG110F8-QFN24T - 32MHz Cortex-M3 MCU | Silicon Labs

Silicon Labs EFM32TG110F8-QFN24T is a 32 MHz ARM Cortex-M3 microcontroller with 8 kB Flash, 2 kB RAM, and 17 digital I/O pins in a 24-QFN 5 x 5 mm package. The device operates from a 1.85 V to 3.8 V supply and includes two 16-bit timers, AES hardware, and three operational amplifiers. A microcontroller is an integrated circuit that combines a processor core, program memory, data memory, and peripherals on one semiconductor die. The EFM32TG110 belongs to the Tiny Gecko family of 32-bit embedded MCUs, placing an ARM Cortex-M3 core within the broader hierarchy of microcontroller, embedded processor, and semiconductor devices. Silicon Labs positions this low-power platform for energy-sensitive embedded products that require fast wake-up operation and energy-saving modes. The principal feature set includes operation up to 32 MHz, 8 kB of Flash, 2 kB of RAM, and 17 digital I/O pins. 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.

Typical applications include IoT sensor endpoints, BLE-enabled beacons, wearable fitness bands, smart-home sensor hubs, industrial HVAC thermostats, battery-powered metering, and remote controls. The wide 1.8-3.8 V supply range simplifies single-cell Li-ion or 2x AA battery designs. When designing with this part, pay attention to the DC-DC inductor selection (the on-chip DC-DC needs an external 10 uH inductor) and the QSPI loading for any external flash expansion. The 32-pin QFN footprint is compact but leaves only 24 GPIO; engineers needing more I/O should step up to the QFP-64 or QFN-64 variants in the same family. This page synthesizes distributor pricing, drop-in alternatives within the same QFN-32 footprint, and practical low-energy design guidance not found in the manufacturer datasheet alone.

EFM32TG222F8-QFP48T - 32MHz Cortex-M3 MCU | Silicon Labs

The Silicon Labs EFM32TG222F8-QFP48T is a 32-bit ARM Cortex-M3 microcontroller operating up to 32 MHz, with 8 KB of Flash memory, 2 KB of RAM, and 37 digital I/O pins in a 48-pin TQFP package. It also includes three operational amplifiers and AES capability, combining general-purpose embedded control with energy-conscious peripheral integration. A microcontroller is a semiconductor device that integrates a processor core, memory, I/O, timers, and communication peripherals into one component. The EFM32TG222F8-QFP48T belongs to the Tiny Gecko family, where the ARM Cortex-M3 core provides a compact instruction set for embedded control. Within the device hierarchy, it is a 32-bit MCU, an embedded processor, and a power-sensitive mixed-signal control platform. Three principal characteristics define this configuration: a maximum CPU speed of 32 MHz, 8 KB of Flash for firmware, and 2 KB of SRAM for working data. The 37 digital I/O pins provide interface capacity for sensors, actuators, human-interface devices, and external control signals. Two 16-bit timers support periodic timing, pulse measurement, and basic motor or signal-generation tasks. The integrated operational amplifiers are useful when a board must amplify weak analog signals without adding separate amplifier packages. AES support is valuable for products that need hardware-assisted encryption and decryption. The low-energy platform, fast wake-up behavior, and energy-saving modes are intended to reduce active and idle consumption in compact embedded systems. Typical uses include battery-powered sensor nodes, industrial condition-monitoring terminals, compact instrumentation, building-control endpoints, and low-power data-acquisition products. The three operational amplifiers can support analog front ends, while the timer and I/O resources can handle periodic sensing and discrete control functions. PCB design should preserve clean analog and digital return paths, especially when the internal amplifiers process low-level signals. Place decoupling capacitors close to the supply pins, route sensitive analog inputs away from switching nodes, and use the manufacturer pin-description table when assigning package leads and programming functions. This product overview combines the core Tiny Gecko specifications, same-package replacement options, interface considerations, and practical selection guidance. It is designed to help engineers evaluate clock performance, memory capacity, peripheral integration, package compatibility, and low-power behavior before completing an embedded design.

The EFM32TG225F16-BGA48 operates at up to 32 MHz and includes 16 KB of Flash, identified by the part number as 16K x 8 bits. Its 48-BGA package supports dense PCB layouts in applications where component area is limited. The 1.85 V to 3.8 V operating range accommodates low-voltage digital systems, while the listed 2.5 V and 3.3 V operating points align with common embedded supply requirements. The device is also identified with AES and operational-amplifier capabilities. The Tiny Gecko platform emphasizes low-power operation through energy-saving modes and rapid wake-up behavior. These characteristics matter in duty-cycled products because the controller can reduce consumption during inactive periods and resume processing quickly when an input, timer, or communication event requires attention. Its Cortex-M3 instruction set supports efficient event handling while providing a familiar software-development environment for embedded toolchains and peripheral configurations. Typical applications include low-power sensor nodes, compact industrial monitoring equipment, energy-aware IoT endpoints, wearable accessories, and embedded control modules. The small 48-BGA package is especially useful where PCB area is constrained, while the 32 MHz processing rate supports responsive control and communication routines. Designers should confirm memory requirements, peripheral assignments, pin functions, and power sequencing in the manufacturer datasheet before finalizing a layout. BGA assembly requires careful PCB design, including controlled pad geometry, appropriate solder-mask and paste patterns, adequate thermal conditions, and inspection coverage for hidden joints. Place stable decoupling close to the supply pins, confirm the operating voltage against every peripheral rail, and use the manufacturer pin-description table when assigning traces. This page also identifies compatible family alternatives and engineering guidance for evaluating a redesign. The information here combines the device architecture, package constraints, sourcing considerations, alternatives, and design guidance into one engineering-focused reference.
