STM32G041F6P6 - 64MHz Cortex-M0+ MCU | STMicroelectronics
部品番号: STM32G041F6P6 ✓ 生産中STM32G041F6P6 概要
A microcontroller is a programmable semiconductor that integrates a CPU core, memory, peripherals, and communication interfaces on one device. The STM32G041F6P6 belongs to the STM32G0 mainstream family and uses the Arm Cortex-M0+ architecture, a 32-bit RISC core designed for energy-efficient control applications. Its role in the broader hierarchy is embedded controller → microcontroller → Arm Cortex-M0+ MCU, where the integrated peripherals reduce the need for external components in control, sensing, and communications products.
Key features include a maximum 64 MHz operating frequency, 32 KB of Flash memory, and 8 KB of RAM. Two USART peripherals support serial communication, while the integrated ADC supports analog measurement functions. AES-256 hardware encryption provides a dedicated cryptographic capability without requiring a general-purpose software implementation. The 1.7 V to 3.6 V supply range allows operation from common low-voltage rails, and the TSSOP-20 package supports compact, surface-mount PCB layouts.
The Arm Cortex-M0+ core provides a straightforward exception-based architecture and efficient instruction execution for embedded workloads. Flash memory retains programmed firmware, while RAM supports stack, variables, and working data. The combination of two USARTs, an ADC, timers, and communication interfaces permits one MCU to consolidate several common peripheral functions, reducing board area and simplifying firmware design in small industrial, consumer, and communications equipment.
Typical applications include compact sensor controllers, serial data concentrators, industrial monitoring nodes, battery-powered instruments, and small communication modules. The STM32G041F6P6 is particularly appropriate when the design needs two serial channels, analog measurement, encrypted data handling, and a 64 MHz control loop without requiring a larger microcontroller package. Its low-voltage supply range also fits systems powered by regulated 3.3 V rails or compatible low-energy power sources.
Designers should verify the complete pin assignment, exposed electrical limits, clock configuration, and peripheral allocation against the manufacturer datasheet before layout release. Decoupling, programming access, reset behavior, and analog-input conditioning remain essential integration details. Because the supplied data does not include a verified pin table, no pin names are inferred in this record, and a footprint-only substitution should not be assumed to be functionally identical.
This page combines verified manufacturer and distributor information, explicit data gaps, application-oriented design guidance, and same-brand drop-in candidates for engineering review. It distinguishes confirmed STM32G041F6P6 attributes from alternatives that require datasheet-level pin, memory, peripheral, and firmware validation before production use.

主な用途
STM32G041F6P6 の用途: 6 件s: Industrial Sensor Controllers, Battery-Powered Measurement Instruments, Serial Data Concentrators, Secure Access-Control Terminals, Compact Communication Modules, Consumer Appliance Control.
Industrial Sensor Controllers
The STM32G041F6P6 fits compact industrial sensor nodes that must acquire analog measurements and report them over two independent serial links. Its integrated ADC avoids a separate analog front-end for suitable low-bandwidth measurements, while the 64 MHz Arm Cortex-M0+ core provides headroom for filtering, scaling, and control calculations. Two USART peripherals can connect a local sensor bus and an upstream controller, reducing component count and board space. The 1.7 V to 3.6 V operating range also accommodates common regulated industrial rails. Design engineers should still verify analog input limits, accuracy, channel multiplexing, and industrial temperature requirements against the manufacturer documentation before releasing production hardware.
Battery-Powered Measurement Instruments
STM32G041F6P6 is appropriate for compact, battery-powered measurement instruments where both processing speed and low-voltage operation matter. A 64 MHz Cortex-M0+ core can service timing, control, and serial-protocol tasks without requiring a higher-power application processor, while the 32 KB Flash and 8 KB RAM provide dedicated firmware and working-memory capacity. The integrated ADC supports measurement functions and the two USARTs allow simultaneous peripheral and host communication. Because the supplied data does not specify sleep currents or wake-up performance, the MCU alone cannot guarantee a battery lifetime; designers should evaluate the complete datasheet and duty cycle alongside the sensor, regulator, and communications hardware.
Serial Data Concentrators
The STM32G041F6P6 can serve as a compact serial concentrator when an embedded product must aggregate data from two serial devices and present a processed result through another interface. Its two USART peripherals reduce the need for an external protocol converter, and the 64 MHz Cortex-M0+ core provides capacity for framing, filtering, and data transformation. The 20-pin TSSOP package preserves routing flexibility in space-constrained boards. A production design should verify USART baud-rate, parity, oversampling, and peripheral-alternate-function assignments because no verified pin table was included in the supplied data. Software support and restart behavior must also be tested if the concentrator handles unattended remote equipment.
Secure Access-Control Terminals
STM32G041F6P6 is suitable for access-control and secure peripheral nodes that require encrypted data handling in a small embedded footprint. Its AES-256 hardware encryption can process supported cryptographic operations more predictably than a software-only implementation, while the 64 MHz Cortex-M0+ core can manage credential transactions, status reporting, and serial communication. Two USARTs can support an external reader or controller alongside a communications link, and the integrated ADC can support simple analog supervisory functions. Engineers must confirm the exact hardware-accelerated cipher modes, key-management approach, clock implementation, and peripheral mapping from official documentation. No claim is made that the MCU alone provides a complete secure element or end-to-end system security.
Compact Communication Modules
The STM32G041F6P6 can complement a wireless or wired communication module by handling low-level configuration, serial framing, and auxiliary control functions. Its 32 KB Flash and 8 KB RAM suit compact protocol stacks, while the integrated ADC, timers, and two USARTs can support sensor inputs, timing tasks, and module control without a separate microcontroller. The 1.7 V to 3.6 V supply range facilitates integration with common 3.3 V communication hardware, although the MCU and radio must share a suitable power architecture. Designers should account for RF-related switching noise, antenna layout separation, protocol timing, and firmware update requirements. The TSSOP-20 footprint also allows the controller to be placed near a connector or status-indicator circuitry.
Consumer Appliance Control
STM32G041F6P6 fits small consumer appliances and embedded control modules that require digital I/O, basic analog sensing, and serial diagnostics. The 64 MHz Cortex-M0+ core can execute motor, valve, display, or button-control logic, while timers simplify periodic tasks and the ADC supports sensor monitoring. Two USARTs allow diagnostics or an external interface, and AES-256 hardware encryption is available where protected command or configuration data is required. The device's 20-pin TSSOP package reduces board footprint, although pin multiplexing must be planned carefully for small control boards. Product developers should verify the operating-temperature range, brownout behavior, flash endurance, and any appliance-specific safety requirements before production.

設計ノート
Place all decoupling capacitors immediately across the STM32G041F6P6 supply pins, with the shortest return path to the associated ground plane. Confirm the required capacitance, voltage rating, and ESR from the official electrical-characteristics documentation before schematic release. Because the verified data does not provide a pin table or recommended capacitor values, do not assign networks to pins based on the TSSOP-20 outline alone; coordinate the layout with the official pin definition.
A shared TSSOP-20 footprint does not by itself prove drop-in compatibility. Before replacing the STM32G041F6P6 with STM32G041F8P6, STM32G031F6P6, STM32G031F8P6, STM32G011F6P6, or STM32G011F8P6, compare every pin name, alternate function, power pin, ground connection, clock input, reset function, and programming interface. Also confirm that firmware, startup code, linker configuration, and peripheral drivers do not depend on features that differ between the STM32G0 variants.
Keep the 64 MHz clock circuit and sensitive analog inputs away from high-current switching nodes and noisy communication return paths. Use short ground references for the ADC and avoid routing measurement inputs beneath digital clock or serial activity where practical. Series damping at external clock and communication sources may be considered after checking edge-rate and capacitance requirements, but exact resistor values are left unspecified because the supplied data does not include the recommended schematic or electrical limits.
Design the 1.7 V to 3.6 V supply rail so that startup, load transients, and peripheral current remain inside the device limits. A 3.3 V rail is consistent with the verified voltage range, but rail tolerance, brownout behavior, and the maximum operating frequency at reduced voltage must be checked in the manufacturer documentation. Separate sensitive analog references or external interfaces from digital return currents where the measured signal precision requires it.
コンプライアンス情報
