STM32F071V8T6 - 48MHz Cortex-M0 MCU | STMicroelectronics
部品番号: STM32F071V8T6 ✓ 生産中STM32F071V8T6 概要
A microcontroller is a programmable semiconductor that executes firmware, reads sensor inputs, controls digital outputs, and manages system communication. The STM32F0 family belongs to the hierarchy of embedded microcontroller, 32-bit RISC processor, Arm Cortex-M microcontroller, and embedded semiconductor. The Cortex-M0 architecture is intended for compact control systems where deterministic execution, low complexity, and broad peripheral integration are more important than high-end processor performance.
The STM32F071V8T6 provides a 48 MHz Cortex-M0 core, 64 KB of Flash memory, and 16 KB of SRAM with hardware parity according to the indexed device data. Its 100-LQFP package exposes 100 connections in a 14 x 14 mm footprint, making it suitable for densely populated embedded control boards. The specified 2.0 V to 3.6 V operating supply supports common 3.3 V industrial, consumer, and instrumentation designs.
The 16 KB SRAM provides working memory for firmware execution, while the 64 KB Flash stores application code and configuration data. The Cortex-M0 core operates at up to 48 MHz, matching the frequency identified by STMicroelectronics, DigiKey, Mouser, and the indexed datasheet. A dedicated CRC calculation unit, reset and power-management functions, and integrated communication capabilities support reliable data handling and peripheral integration.
Typical applications include compact industrial controllers, sensor-hub boards, consumer accessories, communication modules, and low-cost embedded instruments. The 100-LQFP package offers substantially more I/O than smaller microcontroller packages, allowing designers to connect displays, sensors, communication transceivers, and discrete control signals without relying on external I/O expanders.
When designing a PCB, reserve adequate exposed copper and routing clearance for the 100-pin LQFP footprint, follow the manufacturer pin and land-pattern guidance, and place decoupling capacitors close to the supply pins. Validate all peripheral multiplexing, boot behavior, clock configuration, and firmware dependencies before using a related STM32F0 device as a substitute.

主な用途
STM32F071V8T6 の用途: 6 件s: Industrial Control and Automation, Sensor Hub and Environmental Monitoring, Communication and Protocol Interface, Consumer Accessory Controller, LED Lighting and Display Control, Instrumentation and Measurement Front End.
Industrial Control and Automation
The STM32F071V8T6 fits compact machine-control boards that combine digital inputs, outputs, sensors, and local communication. Its 48 MHz Arm Cortex-M0 core provides deterministic embedded processing, while 64 KB of Flash supports application firmware and 16 KB of SRAM provides working memory. The 100-LQFP package offers 100 connections for isolators, drivers, transducers, and status interfaces. Engineers should verify the complete operating-temperature rating, watchdog behavior, and peripheral assignments in the manufacturer documentation before using it in a safety-related or high-availability industrial controller.
おすすめ
Sensor Hub and Environmental Monitoring
The STM32F071V8T6 is appropriate for a multi-sensor node that samples digital or analog sensing channels and forwards results over a serial interface. The 64 KB Flash can retain calibration tables and application code, and the 16 KB SRAM supports protocol buffers and acquisition logic. Its 48 MHz Cortex-M0 core allows responsive peripheral servicing without a higher-cost application processor. The 100-LQFP package simplifies direct connection of multiple sensors and digital isolators, although analog-channel specifications and the exact GPIO alternate functions require verification from the full datasheet.
おすすめ
Communication and Protocol Interface
The STM32F071V8T6 can serve as the host controller for an embedded communication module that needs deterministic firmware execution and several peripheral connections. Its 48 MHz Cortex-M0 core and 64 KB of Flash are suitable for protocol stacks, local configuration, and device management. The 100-LQFP package provides ample connections for a transceiver, indicators, controls, and isolation devices. Design validation should compare the exact USART, SPI, I2C, and timer resources of each candidate because the verified data confirms integrated communications but does not enumerate every peripheral instance.
おすすめ
Consumer Accessory Controller
The STM32F071V8T6 can manage buttons, indicators, relays, sensors, and a serial accessory interface in a compact consumer product. Its 2.0 V to 3.6 V digital and I/O supply supports 3.3 V logic, while the 64 KB Flash and 16 KB SRAM are sized for embedded control rather than a rich graphical user interface. The 100-LQFP footprint provides more I/O than small-outline alternatives but requires adequate PCB area and careful escape routing. Firmware development must include boot, reset, brownout, and peripheral initialization appropriate to the selected STM32F0 device.
おすすめ
LED Lighting and Display Control
The STM32F071V8T6 is usable in LED signage, status displays, and general lighting-control modules where multiple outputs must be updated in real time. Its 48 MHz Cortex-M0 core supports timer-based dimming, key scanning, and communication updates, while the 100-LQFP package offers enough pins to distribute several control signals. The 64 KB Flash stores animation or configuration data and the 16 KB SRAM supports display buffers. Exact timer channels, PWM resolution, and GPIO drive capabilities must be confirmed from the manufacturer datasheet because those values were not included in the supplied verification.
おすすめ
Instrumentation and Measurement Front End
The STM32F071V8T6 suits measurement instruments that need control logic, calibration storage, communications, and several digital I/O connections in a single device. Its 64 KB Flash can hold firmware and calibration information, while 16 KB of SRAM supports acquisition and conversion control. At 48 MHz, the Cortex-M0 core handles protocol tasks and front-panel updates without requiring an external processor. Designers should verify ADC characteristics, timer accuracy, reference voltage, and operating-temperature limits from the complete datasheet before establishing measurement accuracy for this 100-LQFP implementation.

設計ノート
Use the current STMicroelectronics 100-LQFP recommended land pattern and pin-1 orientation rather than scaling a generic 100-pin footprint. Preserve solder-mask and paste geometry specified for the exact package. Because the supplied evidence does not include the complete pin table or recommended PCB artwork, engineers should verify pin numbering, exposed thermal considerations, and assembly tolerances in the official package documentation before fabrication.
The verified digital and I/O supply range is 2.0 V to 3.6 V. Place the required local bypass capacitors close to their associated supply pins, with short ground-return paths, and confirm that every connected peripheral uses voltage levels compatible with the selected supply domain. Do not infer analog or external-supply limits from the digital range; verify those separately in the manufacturer datasheet before connecting sensors or transceivers.
Do not treat a matching package, CPU frequency, and Flash density as sufficient proof of drop-in equivalence. Review alternate-function assignments, timer channels, communication instances, pin mapping, clock topology, startup behavior, and firmware dependencies. This is especially important when moving from STM32F071V8T6 to STM32F072 or STM32F101 devices, where the processor core or memory organization can change software behavior even when the board outline remains similar.
