EDB4432BBBJ-1DAUT-F-D

EDB4432BBBJ-1DAUT-F-D - 4Gbit LPDDR2 SDRAM 533MHz | Micron

The Micron Technology EDB4432BBBJ-1DAUT-F-D is a 4 Gbit Mobile LPDDR2 SDRAM memory IC with a parallel interface, a 533 MHz clock frequency, and a 128M x 32 memory organization, housed in a 134-ball Fine-Pitch Ball Grid Array (134-FBGA, 10 x 11.5 mm) package for surface-mount applications. LPDDR2 (Low Power Double Data Rate 2) is a JEDEC-defined SDRAM family optimized for battery-powered and thermally constrained systems. Compared to standard DDR SDRAM, LPDDR2 reduces core voltage and adds low-power states such as deep power-down and self-refresh, making it a key building block in the mobile power-management hierarchy alongside application processors, PMICs, and NOR/NAND flash. Key features of this device include 4 Gbit density in a single x32组织 die, a 533 MHz data-rate class supporting high-bandwidth streaming, an extended operating temperature range of -40C to +125C for industrial and automotive-adjacent environments, and the FBGA package that minimizes parasitic inductance for signal integrity at high data rates. The marking code for this device is D9XCB, and the -D suffix designates the industrial temperature variant. Architecturally, the memory uses a banked DRAM core with LPDDR2 CA (command/address) multiplexed signaling, which reduces pin count and simplifies PCB routing versus conventional DDR interfaces. The 1.2V-class core supply of LPDDR2 lowers dynamic power substantially compared to 1.5V DDR3-class solutions, which directly extends battery life in portable designs. Typical applications include embedded industrial computing, networking equipment buffering, automotive infotainment and telematics memory, and portable medical or test instruments where an application processor requires 4 Gbit of high-bandwidth working memory over an LPDDR2 interface. A key design consideration is LPDDR2 fly-by-free point-to-point routing: keep trace-length matching tight between the CA bus and clock, and follow the memory controller vendor's guidelines for on-die-termination settings and ZQ calibration to guarantee eye margins at 533 MHz.

EDB4432BBPA-1D-F-D - 4Gbit LPDDR2 SDRAM 128Mx32 FBGA-168 | Micron

The Micron EDB4432BBPA-1D-F-D is a 4 Gbit Mobile LPDDR2 SDRAM organized as 128M x 32 bits per channel in a single-channel configuration. The device operates at a 533 MHz clock rate delivering 1066 Mb/s/pin data rate and is housed in a 168-ball Fine-Pitch Ball Grid Array (FBGA) package measuring 12 x 12 mm. The speed grade 1D variant specifies WRITE latency of 4 and READ latency of 8, providing balanced timing for typical mobile workloads. Mobile LPDDR2 (Low-Power Double Data Rate 2) SDRAM is a class of low-voltage DRAM designed for portable and battery-powered applications. Compared to standard DDR SDRAM, LPDDR2 operates at lower voltage (1.2 V typical VDD) and includes architectural features such as partial-array self-refresh (PASR) and deep power-down (DPD) modes. It sits within the broader taxonomy: volatile memory -> DRAM -> SDRAM -> DDR SDRAM -> Mobile SDRAM -> LPDDR2, and is widely used in smartphones, tablets, and embedded systems where power efficiency is critical. Key features of the EDB4432BBPA-1D-F-D include a supply voltage range of 1.14 V to 1.95 V (1.2 V nominal), operating temperature range of -30C to +85C for commercial/industrial-grade environments, and the compact FBGA-168 12 x 12 mm footprint. The single-channel x32 organization simplifies memory controller design and routing. The 4 Gbit density supports moderate memory arrays in tablets, single-board computers, and embedded multimedia devices. The device uses a JEDEC-standard LPDDR2 interface that supports both HSUL (high-speed unterminated logic) and LVCMOS I/O. The internal architecture employs multiple internal bank groups for reduced power and improved throughput. Refresh management, temperature-compensated refresh, and partial-array self-refresh are supported, enabling power savings when only portions of memory are actively used. Typical applications include Android/Linux-based tablets, portable media players, automotive infotainment displays, single-board computers, and industrial HMI panels. In each scenario, the 1.2 V supply voltage and low-power operating modes directly extend battery runtime. The 128M x 32 organization is well-suited for direct attachment to 32-bit application processors that integrate an LPDDR2 controller. When designing with this device, ensure the host processor includes a JEDEC-compliant LPDDR2 controller and that the PCB layout uses controlled-impedance traces for the high-speed byte lanes. Decoupling capacitors must be placed close to each supply pin, and the ZQ calibration pin must be tied to ground through the specified 240 ohm resistor. The FBGA package requires X-ray or automated optical inspection for solder joint verification.

EDB8164B4PR-1D-F-D - 8Gbit LPDDR2 Mobile SDRAM 216-FBGA | Micron
EDB8164B4PR-1D-F-D

EDB8164B4PR-1D-F-D - 8Gbit LPDDR2 Mobile SDRAM 216-FBGA | Micron

The Micron EDB8164B4PR-1D-F-D is an 8 Gbit Mobile LPDDR2 SDRAM organized as 128M x 64 bits, operating at 533 MHz clock frequency, housed in a 216-ball WFBGA (12x12 mm) package. Designed for low-power mobile applications, it supports a wide operating supply voltage range of 1.14 V to 1.95 V and an industrial temperature range of -30C to +85C (TC), making it well suited for smartphone, tablet, and portable embedded platforms. LPDDR2 (Low-Power Double Data Rate 2) is a class of volatile DRAM that builds on the original LPDDR specification by adding higher bandwidth, lower voltage operation (1.2 V core/1.8 V I/O), and architectural refinements like on-die termination and a command/address architecture. Within the memory hierarchy, LPDDR2 sits between standard DDR2/DDR3 SDRAM and emerging LPDDR3/LPDDR4, optimized specifically for the power envelope and board-area constraints of mobile SoCs. As a dual-channel LPDDR2 device, the EDB8164B4PR pairs two 4 Gbit channels to deliver a wide 64-bit data interface per chip, enabling high throughput for application processors and multimedia subsystems. Key differentiating features include a 533 MHz data rate (DDR2-1066 class effective throughput of 1066 MT/s), a compact 12x12 mm 216-WFBGA footprint, and compliance with JEDEC LPDDR2 standards. The device supports partial-array self-refresh (PASR) and deep power-down modes that significantly reduce standby current, which is critical for battery-powered systems. The wide VDD range (1.14 V-1.95 V) covers both core and I/O supply rails typically required by LPDDR2 designs. Architecturally, the dual-die package (DDP) stacks two 4 Gbit LPDDR2 dies internally to achieve 8 Gbit density while preserving a single-chip footprint and command interface, simplifying PCB layout versus using two discrete 4 Gbit devices. This dual-channel configuration makes the part well matched to mobile APs and application processors that expect a 32-bit or 64-bit LPDDR2 data interface. Typical applications include smartphones and tablets, portable media players, wearable electronics, automotive infotainment head units, mobile routers and IoT gateways, and industrial HMI panels. The -30C to +85C operating range extends suitability beyond consumer mobile into telematics, industrial controls, and outdoor equipment. When designing with this part, observe JEDEC LPDDR2 PCB layout guidelines: route the 64-bit data/CA group as tightly matched lengths, provide adequate decoupling on VDD1/VDD2/VDDQ rails, and place the device close to the host SoC to minimize trace stubs. Designers should also verify that the host memory controller supports the LPDDR2 protocol and 8 Gbit density decoding before committing to layout. This page synthesizes distributor pricing, drop-in same-brand alternatives, design considerations, and a packaging/ball-map reference not found on individual distributor listings, providing engineers with a single-page decision tool for LPDDR2 sourcing.

The device operates from a 1.98 V to 3.8 V supply and includes 24 digital I/O pins, two 16-bit timers, and the Gecko low-power architecture engineered for energy-sensitive applications such as battery-powered IoT nodes and energy-harvesting endpoints. A 32-bit microcontroller (MCU) is a single-chip processor that integrates a CPU core, memory, and interface peripherals on one die. The EFM32G200F16-QFN32T belongs to the broader category hierarchy: 32-bit MCU -> ARM Cortex-M3 MCU -> low-power MCU -> embedded microcontroller -> semiconductor IC. The Cortex-M3 is a 32-bit RISC core delivering 1.25 Dhrystone MIPS/MHz per the manufacturer datasheet, making this MCU suitable for both control loops and event-driven sensor fusion. Key specifications of the EFM32G200F16-QFN32T include 16 kB of Flash program memory (16K x 8 organization), 8 kB of SRAM, an ARM Cortex-M3 core running up to 32 MHz, and a wide 1.98 V to 3.8 V supply range.

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

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.

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

Operating from a 1.98 V to 3.8 V supply, it is engineered for ultra-low-power embedded applications where energy-sensitive operation, fast wake-up time, and autonomous peripheral handling are required. A microcontroller (MCU) is a single-chip computer that integrates a CPU core, non-volatile program memory (Flash), volatile data memory (RAM), and a rich set of peripherals on one die. The Cortex-M3 architecture places MCUs within the broader hierarchy of 32-bit microcontrollers -> ARM Cortex-M family -> ARM Cortex-M3 -> embedded processors -> semiconductors. 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.

EFM32G200F64G-E-QFN32R

EFM32G200F64G-E-QFN32R - 64KB Flash ARM Cortex-M3 MCU | Silicon Labs

The Silicon Labs EFM32G200F64G-E-QFN32R is an ultra-low-power ARM Cortex-M3 Gecko microcontroller delivering 32 MHz performance with 64 KB Flash and 16 KB RAM in a 32-pin QFN (6x6) package, supplied on tape and reel for high-volume assembly. Key features include a single 1.98 V to 3.8 V supply rail, 24 digital I/O pins, 2 x 16-bit timers, integrated low-energy peripherals, hardware AES crypto accelerator (AES Excluded on this G-grade variant), 2-pin Serial Wire Debug, 1-pin Serial Wire Viewer, and a pre-programmed USB/UART bootloader. 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.

The EFM32G222F32-QFP48 is available in a 7x7 mm 48-pin TQFP package, making it suitable for compact PCB layouts. Its 32-bit ARM Cortex-M3 core and peripheral mix can handle motor-control tasks, industrial monitoring, consumer accessories, and connected sensor nodes. Designers should select the appropriate operating voltage, pin multiplexing, clock configuration, and low-power strategy for the target system. Typical applications include low-power sensor nodes, industrial condition-monitoring equipment, small motor controllers, building-control endpoints, and portable measurement products. In each case, the MCU controls acquisition, timing, logic, and external interfaces while using its low-power modes between activity periods. The exact input voltage limits, current consumption, pin names, package dimensions, and electrical limits must be taken from the manufacturer datasheet rather than inferred from distributor summaries. A key design consideration is the relationship between sleep-mode selection and wake-up latency. For battery-powered systems, choose the lowest acceptable active and sleep currents while ensuring that the required peripherals respond within the control-loop timing budget. Also budget Flash, RAM, stack depth, and firmware overhead before adding protocol libraries or advanced control algorithms. This page combines manufacturer specifications, distributor product information, datasheet access, package details, and engineering guidance to support component selection and PCB planning. It is intended to make the EFM32G222F32-QFP48 searchable by MPN, ARM Cortex-M3, 32 MHz, 32 kB Flash, 8 kB RAM, and 48-pin TQFP-related design requirements.

Its ARM Cortex-M3 core provides a 32-bit processing architecture for real-time control, while the Gecko platform focuses on reducing energy use between short processing bursts. Key features include a maximum clock frequency of 32 MHz, 64 kB of Flash for firmware, and 16 kB of RAM for working data. The device provides 37 digital I/O pins and three dedicated 16-bit timers, making it suitable for products requiring multiple control outputs, periodic sensing, motor or actuator timing, and low-power autonomous behavior. The 48-TQFP package is 7 mm by 7 mm and supports surface-mount PCB assembly. The Cortex-M3 architecture and low-power Gecko design make this MCU appropriate for always-on embedded subsystems that must react quickly without continuously consuming maximum power. The verified manufacturer and distributor descriptions specifically identify fast wake-up times and energy-saving modes as platform capabilities. Detailed peripheral lists, memory organization, voltage limits, temperature limits, and package dimensions beyond the supplied data should be confirmed in the manufacturer documentation before a final design is released.

Designers can allocate the 64 kB Flash region to application firmware and configuration data while using the 16 kB RAM for working buffers. The three 16-bit timers support periodic counting, input capture, output compare, or other timing functions depending on the device configuration. The primary design consideration is low-power system architecture. Sensors, communications, and actuator drivers should be enabled only when required, and firmware should use the MCU's sleep and wake behavior to reduce average consumption. PCB layout should preserve clean grounding and short signal paths, while production firmware should be validated across voltage, temperature, and wake-up conditions intended for the end product. This page combines the verified manufacturer specifications, distributor availability references, package details, and practical engineering guidance. It also distinguishes exact same-package family options from devices that differ materially in memory or generation, preventing those parts from being presented as unqualified drop-in replacements.

The Gecko series targets battery-powered systems with typical Stop current of 0.6 uA and Run current of 180 uA/MHz per the EFM32G datasheet. The device operates across the industrial -40C to +85C range. Architecturally, the part uses a Cortex-M3 core with a peripheral reflex system (PRS) that lets peripherals signal each other without CPU intervention - a key energy saver. Flash and RAM are accessed through the AHB-Lite bus, and low-energy peripherals are placed on a separate APB bus so they can run while the CPU sleeps. Typical applications include battery-powered IoT sensors, wearable health monitors, smart metering, wireless sensor nodes paired with sub-GHz or BLE companions, and industrial HMI / alarm panels. The integrated AES block is suitable for encrypted firmware update and secure authentication. When designing with this device, plan the decoupling network carefully: place 100 nF and 1 uF capacitors as close as possible to each VDD pin pair, and follow the EFM32G hardware design guide for the 32 kHz crystal layout to avoid extra current draw from a high-ESR load. A JTAG or SWD header is required for programming - the on-chip debug interface is supported by Simplicity Studio and the J-Link toolchain.

This peripheral integration reduces external bill-of-materials for sensor and metering designs, while the autonomous LESENSE block can scan capacitive or inductive sensors in deep sleep. The architecture centers on a low-leakage CMOS process and energy-modes-aware clock gating, allowing the device to enter EM2/EM3 deep-sleep states while still triggering wakeup from GPIO, RTC, or LESENSE events. The peripheral reflex system (PRS) routes peripheral events over dedicated fabric channels, offloading routine signal routing from the CPU and enabling sub-microsecond response without leaving sleep. Typical applications include battery-powered IoT sensor nodes, smart HVAC thermostats, water/gas utility metering, wireless sensor hubs front-ending sub-GHz radios, wearable health patches, and industrial asset tracking tags. The on-chip AES-128 block and 128KB Flash also suit retrofit devices that need authenticated firmware updates over BLE/Zigbee companion ICs. When designing with the EFM32G232F128G-E-QFP64R, budget decoupling capacitors close to every VDD/VDD_x pair, route the 32kHz crystal traces symmetrically, and leverage the EFM32 CMSIS-Pack and Simplicity Studio for peripheral configuration to avoid hidden power draw from misconfigured GPIO retention modes.

It belongs to the EFM32 Gecko family, a low-power 32-bit MCU platform built around energy-conscious techniques, fast wake-up times and multiple energy-saving modes. An MCU (microcontroller) is a single integrated circuit containing a CPU core, program memory, data memory and peripherals. In the taxonomy a microcontroller is a type of integrated circuit and semiconductor, and within that group it sits beside memory ICs, interface ICs, ADC/DAC and clock & timing devices. The Gecko family specifically targets energy-sensitive embedded systems where average current draw, not just peak performance, determines battery life. Key features of this device include a 32 MHz ARM Cortex-M3 core with integrated sleep and stop modes, 64 kB of flash for firmware and 16 kB of SRAM for working memory, three 16-bit timers, and hardware AES support as noted in the Mouser listing for this part number. A wide 1.98 V to 3.8 V supply range makes the part usable across 2.5 V and 3.3 V system rails, and the 64-TQFP 10x10 mm footprint keeps the board area small while exposing 53 GPIO for sensors, actuators and communications. Technically the part belongs to the Gecko series, whose energy-saving modes and fast wake-up behaviour are the differentiating architectural features versus generic Cortex-M3 devices. Because the device is available in a 64-pin TQFP, designers get both fine-grained pin multiplexing and a package that is straightforward for automated assembly, pick-and-place and visual inspection, unlike fine-pitch QFN or BGA options. Typical applications include low-power sensor nodes and IoT end devices, industrial monitoring and control modules, building and energy metering equipment, portable and wearable accessories, and USB-connected peripheral controllers where the 53 available I/O pins allow several peripherals to share one package. A key design consideration is that the flash capacity and RAM size define how much application code and data buffering fit on the die; designs that need large buffers should consider the 128 kB and 256 kB members of the Gecko family instead of this 64 kB variant. This page synthesizes distributor pricing, verified drop-in alternatives, pin-level guidance and practical design notes that are not found together in the manufacturer datasheet, helping engineers shorten BOM and layout decisions for EFM32G232F64-QFP64.

A microcontroller is a programmable semiconductor that combines a processor core, memory, and peripherals on one integrated circuit. The EFM32G30F128-QFN64 belongs to the Gecko family of 32-bit ARM Cortex-M3 microcontrollers, which sit within the hierarchy of embedded processors, microcontrollers, and semiconductor control devices. Its ARM Cortex-M3 core provides a 32-bit instruction set while the EFM32 peripheral architecture allows many hardware functions to operate with limited CPU involvement. The verified device data identifies a maximum clock frequency of 32 MHz, 128 KB of flash organized as 128K x 8, and 16 KB of SRAM. Silicon Labs specifies a 1.98 V to 3.8 V operating supply range and a 64-QFN package measuring 9 x 9 mm. The family datasheet also reports low power consumption, including as little as 0.6 uA in Stop mode and 180 uA/MHz in Run mode, making the device suitable for battery-powered and energy-conscious products. The Gecko architecture integrates high-speed analog and digital peripherals with the Cortex-M3 core. Product Revision E documentation identifies pin-compatible replacements for earlier EFM32G revision devices. However, firmware, peripheral configuration, and electrical behavior must still be checked against the specific part-number suffix before treating a related revision as a production substitute. A complete exposed-pad thermal design is essential because heat removal depends on the PCB copper area and thermal via arrangement. Typical uses include industrial sensing and control nodes, compact environmental monitors, battery-powered IoT endpoints, wearable accessories, and connected measurement instruments. The small 9 x 9 mm QFN footprint supports space-constrained designs where a larger quad flat package would be undesirable. The 128 KB flash capacity provides room for application firmware, protocol stacks, and boot code, while the 16 KB RAM supports task working memory and moderate buffering. Designers should follow the manufacturer's recommended power, decoupling, and exposed-pad land-pattern requirements. A high-quality local ground plane and short return paths help analog and digital sections remain stable under switching loads. Confirm the exact operating temperature grade, peripheral mix, and pin multiplexing for the ordered MPN before layout release because the verified distributor data does not specify those complete values. This page consolidates verified manufacturer specifications, distributor availability information, pin-compatible same-family options, package constraints, and practical engineering guidance. The comparison material also distinguishes genuine drop-in choices from related devices that require firmware or board-level qualification.

Its combination of low-power design, fast wake-up capability, and energy-saving operating modes targets embedded systems where battery life and deterministic control are important. A microcontroller is a programmable system-on-chip that integrates a CPU, memory, peripherals, and I/O into one package. The EFM32G842 belongs to the EFM32 Gecko family, which combines an ARM Cortex-M3 processor with energy-management hardware for low-power embedded control. This places it in the hierarchy of embedded microcontroller, 32-bit MCU, ARM Cortex-M3 processor, and semiconductor device. The device provides 32 kB Flash for program storage and 8 kB RAM for working data. The verified manufacturer information also identifies three 16-bit timers and 53 digital I/O pins. The 32 MHz CPU supports responsive control, while low-energy modes and fast wake-up behavior can reduce inactive-system power. Its 2.5 V and 3.3 V supply references are identified in the verified distributor material. The EFM32G842F32-QFP64 is suited to energy-sensitive embedded products, including sensor nodes, industrial monitoring equipment, portable instrumentation, and connected low-power systems. Its timer resources can support periodic measurement, motor or actuator timing, and control-loop tasks. The digital I/O count provides flexibility for buttons, displays, sensors, relays, and communications peripherals, subject to the device's electrical and multiplexing limitations. For PCB design, preserve the exact 64-pin TQFP footprint and verify the complete manufacturer pin assignment before routing. Pay particular attention to supply decoupling, ground-return paths, exposed thermal behavior, and any pins assigned to debug, programming, reset, or alternate functions. Firmware should use the Silicon Labs device support configuration for the exact MPN. This product data combines the verified Silicon Labs device description, distributor specifications, package information, lifecycle-related source material, and application-oriented guidance. It is intended to support initial design review, sourcing, and comparison; final production decisions should be checked against the latest manufacturer datasheet and authorized distribution records. This page synthesizes the supplied manufacturer and distributor information with practical selection context. Because no verified price, detailed timing specification, pin table, or approved cross-brand substitute was supplied, those fields are marked as unavailable rather than inferred.

EFM32G842F64-QFP64 - 32MHz Cortex-M3 MCU | Silicon Labs

The Silicon Labs EFM32G842F64-QFP64 is a 32-bit ARM Cortex-M3 microcontroller operating up to 32 MHz, with 64 kB of Flash memory and 16 kB of RAM in a 64-TQFP 10 mm × 10 mm package. The device provides 53 digital I/O pins and three 16-bit timers, combining general-purpose embedded control with low-power operation for energy-sensitive equipment. A microcontroller is a compact integrated circuit containing a processor core, memory, peripherals, and I/O. The EFM32G842 belongs to the EFM32 Gecko family and uses the ARM Cortex-M3 RISC core, placing it in the hierarchy MCU → 32-bit microcontroller → embedded processor → semiconductor. Its low-energy architecture, fast wake-up behavior, and energy-saving modes make it suitable for systems that spend substantial time idle or operate from limited power budgets. Verified features include a 32 MHz operating speed, 64 kB Flash, 16 kB RAM, 53 digital I/O pins, and three 16-bit timers. The 1.98 V to 3.8 V supply range supports 2.5 V and 3.3 V system designs. The LCD, AES, and USB-related ecosystem description shown by distributor listings makes the device relevant to human-interface, secure accessory, and connected embedded applications, while the 64-pin package provides a substantial peripheral-routing option for mixed-signal control boards. The Gecko platform emphasizes fast startup and low-energy execution rather than only peak processing speed. This is valuable in portable instruments, battery-powered sensors, industrial controls, and USB peripherals where the average current between activity periods can determine battery life. Firmware should therefore use the device's sleep and wake behavior deliberately rather than treating the 32 MHz CPU frequency as a continuous-power requirement. Typical applications include energy-harvesting sensors, compact industrial controllers, USB-connected human-interface devices, secure embedded accessories, and low-power monitoring systems. The 53 digital I/O pins are useful for status indicators, buttons, relays, displays, and external interface signals, while the timers support periodic sensing, motor timing, or control-loop tasks. PCB design should preserve short, clean return paths around the MCU and decoupling connections. Follow the manufacturer datasheet for the exact pin names, exposed pad requirements, crystal requirements, and decoupling network. Do not assume that another 64-TQFP MCU is interchangeable solely because its package matches; peripheral mapping, voltage tolerance, firmware support, and pin function must be checked before replacement. This page consolidates verified manufacturer and distributor information, distinguishes the target from unverified alternatives, and adds procurement and design guidance that is not normally present in a basic distributor listing.
