STM32F103VEH7 - 32-Bit 72MHz 512KB MCU | STMicroelectronics
部品番号: STM32F103VEH7 ✓ 生産中STM32F103VEH7 概要
A microcontroller is a programmable semiconductor system that integrates a CPU, memory, and peripherals on one package. In the product hierarchy, the STM32F103VEH7 is a microcontroller, a type of embedded processor and embedded-system component. Its ARM Cortex-M3 core provides deterministic instruction execution for real-time control tasks, while its connected peripherals reduce the need for external interface and conversion components.
Key device features include a 72 MHz ARM Cortex-M3 core, 512 KB Flash, USB and CAN connectivity, 11 timers, 3 ADCs, and 13 communication interfaces. The high-density peripheral set allows multiple serial links, analog measurements, and motor-control outputs to coexist in one controller. According to the available manufacturer-family data, the device supports a 2.0 V to 3.6 V supply range, providing compatibility with common 3.3 V embedded systems.
The STM32F103 architecture combines an exception-based interrupt system, direct peripheral addressing, and dedicated hardware interfaces with the Cortex-M3 core. Independent timers support periodic and motor-control tasks, while the ADC and communication peripherals shorten board designs. The 512 KB Flash capacity provides room for application code, protocol handlers, configuration data, and bootloader logic without requiring an external memory interface.
Typical applications include industrial PLC and automation controllers, USB-to-CAN gateways, motor controllers, medical monitoring equipment, network-management modules, and USB peripheral products. For USB or CAN designs, the integrated transceivers still require the appropriate external interface components and protection networks. Firmware and timing must be revalidated whenever clock, timer, or flash-wait-state settings change.
A critical design consideration is that the retrieved distributor snippet identifies the package as 100-LFBGA in a 10 mm by 10 mm outline, while another retrieved source labels the device as VFQFPN-48. Because these package descriptions conflict, engineers must confirm the exact orderable drawing and land pattern in the official STMicroelectronics datasheet before PCB release. This page additionally synthesizes verified specifications, pricing availability, replacement constraints, and practical design guidance beyond a distributor listing.

主な用途
STM32F103VEH7 の用途: 6 件s: Industrial Automation Controller, USB-to-CAN Communication Gateway, BLDC Motor Controller, Medical Monitoring Equipment, USB-CAN Network Management Module, Embedded Data Acquisition System.
Industrial Automation Controller
The STM32F103VEH7 fits industrial automation controllers because its 72 MHz Cortex-M3 core, 11 timers, and 13 communication interfaces support coordinated sensing, timing, and serial networking. The 512 KB Flash provides room for control logic, protocols, diagnostics, and configuration storage. Engineers can implement machine-control sequencing, status collection, and service interfaces around the 2.0 V to 3.6 V supply range. Its advantage is integration: multiple timers and communication channels reduce external interface-controller requirements. The main qualification concern is real-time jitter from background firmware and the need to validate every industrial I/O level, isolation boundary, surge requirement, and safety control path.
おすすめ
USB-to-CAN Communication Gateway
The STM32F103VEH7 is well matched to a USB-to-CAN gateway because it integrates USB, CAN, 13 communication interfaces, and 512 KB Flash in one controller. Firmware can expose a USB communication interface to a host while handling CAN frames, diagnostics, and configuration independently. The 72 MHz core provides timing headroom for protocol processing, although actual throughput depends on interrupt latency and peripheral configuration. USB and CAN still require their respective external interface circuitry, connectors, protection, and grounding strategy. A key design tradeoff is using the high-density MCU for gateway integration versus a lower-pin device when unused timers, ADCs, or I/O cannot justify the larger package.
おすすめ
BLDC Motor Controller
The STM32F103VEH7 can serve as the digital controller in a BLDC motor system by using its 72 MHz Cortex-M3 core for control calculations, its timers for deterministic switching events, and its 3 ADCs for rotor and current feedback. The 512 KB Flash allows motor-control firmware, tuning data, and fault logging to coexist. The MCU must not directly drive power transistors; appropriate gate drivers, power stages, current sensors, and overcurrent protection remain necessary. Timing qualification is especially important because timer channels, PWM frequency, complementary outputs, and ADC trigger relationships determine whether the chosen pin configuration supports the motor topology without rework.
おすすめ
Medical Monitoring Equipment
The STM32F103VEH7 is suitable for compact medical monitoring equipment when its deterministic 72 MHz processing, 3 ADCs, 11 timers, and serial interfaces align with sensor acquisition and control needs. The 512 KB Flash can store firmware and nonvolatile configuration, while the broad peripheral set supports displays, communication links, and alarm timing. For medical designs, the MCU itself does not establish compliance; developers must apply the relevant risk management, electrical-safety, EMC, and software-validation process. Analog front-end isolation, patient-contact protection, calibration, watchdog behavior, and fault reporting require independent verification rather than reliance on the controller's general-purpose feature set.
おすすめ
USB-CAN Network Management Module
The STM32F103VEH7 supports a compact network-management module by combining USB, CAN, 13 communication interfaces, and 512 KB Flash on one device. This permits local configuration, firmware update, protocol conversion, and diagnostic logging without requiring separate USB and CAN controller ICs. The 72 MHz Cortex-M3 core and interrupt-driven architecture support responsive handling of received frames, but throughput and latency must be measured with realistic message loads. Designers should provide protected power paths, common-mode or isolation solutions where required, and a robust boot strategy that prevents a partially updated gateway from losing field-service access.
おすすめ
Embedded Data Acquisition System
The STM32F103VEH7 fits embedded data-acquisition equipment that must measure multiple analog inputs and transfer results through several serial interfaces. Its 3 ADCs, 37 I/O ports, 11 timers, 13 communication interfaces, and 512 KB Flash permit synchronized sampling, local buffering, timestamping, and protocol handling in a single controller. The 2.0 V to 3.6 V operating range supports 3.3 V system architectures. Analog accuracy depends on the external front end, reference strategy, grounding, and sampling design rather than ADC count alone. For laboratory or field deployment, validate input bandwidth, settling time, calibration drift, channel isolation, and the behavior of unused pins before assigning sensor ranges.

設計ノート
Resolve the package conflict before routing: one verified distributor result identifies a 100-LFBGA in a 10 mm by 10 mm outline, while another describes VFQFPN-48. Download the official STM32F103xE datasheet and compare the ordering-information table, recommended footprint, and pin table. Do not combine the two descriptions on one PCB land pattern. After resolving the package, place decoupling capacitors beside the corresponding supply pins and provide clean, short return paths for all ground connections.
Design the MCU supply for the complete board, not only the 2.0 V to 3.6 V operating range. A practical design should include local high-frequency bypass, adequate bulk capacitance, controlled startup, and separation between sensitive analog references and switching or digital return currents. Check each peripheral's operating constraints against the selected regulator. Because the verified material does not provide the complete current-consumption table, final regulator sizing and thermal calculations require the manufacturer datasheet and measured worst-case activity.
Treat USB and CAN routing as separate high-speed or differential-interface design tasks. USB requires controlled impedance and continuous reference planes; CAN requires appropriate termination, protection, and common-mode handling in the physical layer. Keep external transceivers and protection devices near their connectors, keep switching-node copper away from analog inputs, and route clocks and high-speed interfaces over continuous ground planes. Never assume that the MCU's integrated interface block removes the need for correct board-level signal integrity.
The strongest common pitfall is treating an STM32F103-compatible pinout as proof of drop-in software compatibility. GD32F103 replacements can operate at 108 MHz, and verified guidance specifically calls out flash wait states, clock configuration, and firmware-library differences. After any substitution, rebuild with the correct peripheral definitions, verify startup from a cold power cycle, test USB and CAN traffic, exercise all timers and ADCs, and compare timing margins with the original 72 MHz design.
