EFM32G200F32-QFN32 - ARM Cortex-M3 32MHz MCU 32KB Flash | EFM32 Gecko

The Silicon Labs EFM32G200F32-QFN32 is an ARM Cortex-M3 based microcontroller from the EFM32 Gecko family, delivering up to 32 MHz core speed with 32 kB Flash and 8 kB RAM, housed in a 32-pin QFN (6x6 mm) package with exposed pad. A microcontroller (MCU) is a single-chip computer containing a processor core, program memory (Flash), working memory (RAM), and a rich mix of peripherals such as timers, ADCs, communication interfaces, and GPIO. The Cortex-M3 core implements the ARMv7-M instruction set with hardware multiply/divide and the Thumb-2 instruction encoding, giving 32-bit performance at 16-bit code density. MCU taxonomy: microcontroller -> embedded MCU -> ARM Cortex-M MCU -> Cortex-M3 MCU -> low-power Cortex-M3 MCU. The EFM32 Gecko family sits at the low-power end of this hierarchy, optimized for battery and energy-harvesting designs. Key features include 24 digital I/O pins (capable of 5V tolerance on most pins), 2 x 16-bit timers plus a 16-bit RTCC, multiple serial interfaces (USART, I2C, USB), a 12-bit ADC, and a low-energy peripheral fabric that can operate while the CPU is asleep. The supply range of 1.98V to 3.8V allows direct connection to a single Li-ion cell or two AA cells, and the deep-sleep current is in the microamp range. Architecturally, the Gecko platform separates the Cortex-M3 core domain from an autonomous low-energy peripheral domain, so ADCs, comparators, and timers can run from LFCLK (32.768 kHz) without waking the CPU. This LESENSE-style partitioning is what enables the family's sub-uA sleep currents and microjoule event response times. Typical applications include IoT sensor nodes, wireless battery powered wearables, smart metering, HVAC sensor nodes, and any batteryless smart-building. The 32-QFN footprint helps compact designs in space-constrained PCBAs. When designing with this device, plan the decoupling network between the supply pins and across DECOUPL pins and respect the exposed-pad PCB layout for thermal and ECS reliability.

EFM32G200F64-QFN32

EFM32G200F64-QFN32 - 32MHz Cortex-M3 MCU, 64KB Flash | Silicon Labs

The Silicon Labs EFM32G200F64-QFN32 is an ARM Cortex-M3 based 32-bit microcontroller running at up to 32 MHz with 64 KB of Flash and 16 KB of RAM, housed in a 32-pin QFN (6x6 mm) package. Built on the Gecko low-energy platform, the EFM32G200F64-QFN32 targets energy-sensitive embedded applications where short wake-up time and multiple low-power modes are mandatory, providing 24 digital I/O pins, two 16-bit timers, and a flexible energy management system that delivers Cortex-M3 throughput at substantially lower active and sleep current than legacy 8/16-bit parts. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, program and data memory, and a wide range of peripherals such as timers, ADC/DAC, communication interfaces, and GPIO. The Cortex-M3 family specifically is a Harvard-architecture 32-bit RISC core with Thumb-2 instruction set, deterministic interrupt handling, and an optional Memory Protection Unit. The EFM32 Gecko series places that core inside a power-aware system hierarchy (MCU -> Cortex-M3 MCU -> low-energy MCU -> ARM Cortex family -> 32-bit embedded processor), giving it a clear positioning between general-purpose Cortex-M3 parts and ultra-low-power Cortex-M0+ devices. Key differentiating features of the EFM32G200F64-QFN32 include the integrated Wake-up Interrupt Controller (WIC) that allows peripherals to wake the CPU directly from deep-sleep without an enabled system clock, and the LESENSE / peripheral reflex system that lets sensor interfaces run autonomously. The WIC and Energy Management Unit are direct contributors to the part's energy-friendly specification: very fast wake-up, multiple EM0-EM4 sleep modes, and low-leakage GPIO retention. The architecture is a 32-bit ARM Cortex-M3 core fabricated on a low-leakage CMOS process, supporting up to 32 MHz with 1.25 Dhrystone MIPS/MHz and an MPU supporting up to 8 memory segments. Compared with earlier 8/16-bit microcontrollers, the EFM32G200F64-QFN32 provides roughly an order-of-magnitude higher compute density per joule, and the QFN-32 (6x6 mm) package keeps the footprint compatible with space-constrained IoT and sensor designs. Typical applications include battery-powered wireless sensor nodes, energy-harvesting devices, smart-metering endpoints, wearable health and fitness products, and industrial IoT edge nodes where the MCU spends most of its life in sleep and wakes only briefly to process sensor data. The wide 1.98 V to 3.8 V supply range also supports single-cell Li-ion or two-AAA cell topologies. When designing with this part, pay close attention to decoupling (one 100 nF per VDD pin group plus a bulk cap), the routing of the RESETn line, and the unused-pin tie-off to avoid floating inputs that increase sleep current. Designers migrating from 8-bit parts should re-evaluate the interrupt priority model, as the Cortex-M3 NVIC allows nested pre-emption that 8051/PIC designs do not provide. This page synthesizes distributor pricing, drop-in alternatives, and practical low-power design notes not found in the manufacturer datasheet alone, providing an engineering reference for procurement and design teams evaluating the EFM32G200F64-QFN32.

The EFM32G product line targets low-energy applications such as battery-powered IoT nodes, wearables, and sensor interfaces where typical Cortex-M3 microcontrollers would consume far more power. Key features include 24 digital I/O pins, 2x 16-bit timers, an integrated AES peripheral (No AES variant per the Mouser listing), and energy-saving modes that draw as little as single-digit microamps in Stop mode. The device supports peripheral reflex system (PRS) and low-energy peripherals that allow autonomous operation without waking the CPU. Independent hardware AES is excluded from this -G part variant. The 32-QFN (6x6) package is compact, has a low thermal resistance thanks to the exposed pad, and suits space-constrained PCB layouts. Typical applications include battery-operated IoT sensor nodes, smart home wireless or wired bridges, wearable health monitoring patches, industrial sensor endpoints, and remote controls. Compared with discrete 8-bit MCU solutions, the EFM32G200F64G-E-QFN32 delivers 32-bit performance while still operating in the microamp current envelope demanded by multi-year battery life targets. When designing with this part, route decoupling capacitors directly to the exposed pad which is the device's ground return. Use the energy modes (EM0-EM4) aggressively - peripherals run in EM2 while the CPU sleeps, which is the key to the Gecko's energy efficiency. Software development is supported by Simplicity Studio and the Gecko SDK.

The Cortex-M3 core delivers 1.25 DMIPS/MHz with single-cycle multiplier and hardware MAC, while the autonomous peripheral reflex system allows I/O events to wake the MCU without CPU intervention. The EFM32G200F64G-E-QFN32R is built on the Gecko architecture from Energy Micro (acquired by Silicon Labs), which pioneered sub-microamp sleep current for battery-operated designs. Compared to a generic Cortex-M3, the Gecko adds an LESENSE block, on-chip op-amps, a 5V-tolerant GPIO structure, and an ultra-efficient Power-on Reset / Brown-Out Detector, giving designers a tightly integrated SoC rather than a raw MCU. Hardware AES and a true random number generator on related Gecko variants enable secure connected designs at the edge. Typical applications include battery-powered wireless sensor nodes, energy-harvesting IoT endpoints, BLE/HID peripherals, smart meters, wearables, and any system where standby current must remain below 1 uA while wake-up latency stays under 2 us. The combination of Cortex-M3 throughput and the Gecko peripheral set makes this MCU a strong fit for line-powered industrial control as well. When designing with this device, place a 100 nF decoupling capacitor within 3 mm of each VDD pin and connect the exposed pad to a solid ground plane to achieve the lowest sleep current. The integrated DC-DC converter requires an external 4.7 uH inductor and 4.7 uF bypass capacitor to operate efficiently above 10 mA loads.

EFM32G232F32-QFP64 - 32MHz Cortex-M3 MCU | Silicon Labs

The Silicon Labs EFM32G232F32-QFP64 is an ARM Cortex-M3 32-bit microcontroller operating up to 32 MHz, with 32 kB of Flash memory, 8 kB of RAM, and 53 digital I/O pins in a 64-TQFP package. It combines conventional embedded processing with a low-power Gecko platform designed for energy-sensitive systems. A microcontroller is a programmable system-on-chip that integrates a processor core, memory, peripherals, and I/O into one device. The ARM Cortex-M3 belongs to the embedded microcontroller hierarchy, while the EFM32G family adds low-power design techniques, fast wake-up behavior, and energy-saving modes. This makes the device suitable when a design needs more control capability than a simple fixed-function controller without adopting a more complex high-performance processor. The EFM32G232F32-QFP64 provides 32 kB Flash for firmware and 8 kB RAM for working data. Its 53 digital I/O pins support external sensors, indicators, switches, communications interfaces, and control signals. Three 16-bit timers are included for periodic events, timing, input capture, output compare, or other timer-based functions. The 32 MHz Cortex-M3 core provides a balance of processing speed and low-power operation for embedded control. The verified manufacturer result specifically identifies the device as an ARM Cortex-M3 based MCU with speeds up to 32 MHz and highlights its low-power platform, fast wake-up times, energy-saving modes, 32 kB Flash, 8 kB RAM, 53 digital I/O pins, and three 16-bit timers. Exact supply voltage, peripheral details, package dimensions, temperature limits, memory organization, and electrical characteristics were not included in the supplied source snippets and therefore remain marked where data is needed. Typical uses include low-power sensor nodes, industrial control products, building automation modules, connected measurement equipment, small motor-control systems, and portable embedded instruments. The 64-TQFP package exposes more I/O than smaller packages and can simplify board-level routing when a design requires several external connections. Compared with a low-pin-count MCU, the EFM32G232F32-QFP64 offers additional I/O flexibility while retaining a compact surface-mount form factor. Designers should verify the complete manufacturer datasheet before layout, firmware development, or production release. Pay particular attention to power sequencing, decoupling, exposed-pin requirements, clock configuration, programming method, peripheral multiplexing, and the exact meanings of all 64 package pins. The supplied data supports the core, memory, speed, I/O, timer, package, and low-power claims above but does not provide a complete electrical table. This page consolidates the verified manufacturer and distributor search results, records unavailable technical fields transparently, and distinguishes the target MCU from package-only or functionally similar alternatives. The primary sourcing path is the Silicon Labs product page, supplemented by distributor records for procurement and additional datasheet discovery.
