部品番号: STM32F103ZFH6 ✓ 生産中STM32F103ZFH6 概要
A microcontroller is an integrated circuit that executes embedded software while coordinating digital inputs, outputs, communications, and analog measurements. Within the product hierarchy, the STM32F103ZFH6 is an ARM Cortex-M3 MCU, a 32-bit microcontroller, and a member of STMicroelectronics' STM32 embedded-processing family. It is intended for systems that require substantially more Flash memory and I/O than small 8-bit or 16-bit control devices.
The verified product information identifies the STM32F103ZFH6 as a 72 MHz device with 768 KB of Flash organized as 768K x 8. Its 32-bit Cortex-M3 core provides the processing foundation for control loops, communications gateways, human-interface systems, and data acquisition. The 144-LFBGA package supplies 144 connection points in a compact 10 x 10 mm surface-mount footprint suitable for multilayer PCB designs.
The STM32F103 family is associated with USB, CAN, six timers, two ADCs, and six communication interfaces. These functions support designs connecting external digital devices, transferring data over serial or network links, measuring analog signals, and controlling time-dependent peripherals. The available verified data does not specify individual GPIO counts, SRAM capacity, ADC resolution, or communication baud-rate limits, so those values must be confirmed in the manufacturer datasheet before final system design.
Typical applications include industrial automation equipment, USB-connected embedded controllers, CAN network nodes, data-acquisition systems, motor and motion-control platforms, and communication equipment. The 72 MHz Cortex-M3 core can manage multiple interrupt-driven peripherals while the 768 KB Flash capacity accommodates larger embedded applications, protocol stacks, and application firmware.
The principal design consideration is package and PCB complexity. A 144-LFBGA device requires a multilayer board, fine-pitch routing, controlled escape routing, and careful thermal management. Designers should also verify peripheral assignments, pin multiplexing, power sequencing, decoupling, and firmware support against the exact datasheet and reference manual before releasing hardware.
This page consolidates verified distributor pricing, package details, technical attributes, sourcing links, and design guidance into one engineering-focused reference. It also distinguishes explicitly verified information from parameters that require confirmation from the manufacturer datasheet.

主な用途
STM32F103ZFH6 の用途: 6 件s: Industrial Automation Controller, USB-CAN Network Gateway, Data Acquisition and Sensor Hub, Motor and Motion Control Platform, USB Embedded Control Device, Communication Equipment.
Industrial Automation Controller
The STM32F103ZFH6 fits industrial automation controllers that combine responsive control logic with several communication and timing resources. Its 72 MHz Cortex-M3 core and 1.25 DMIPS/MHz performance provide capacity for interrupt-driven machine-control tasks, while the verified family feature set includes six timers, two ADCs, USB, CAN, and six communication interfaces. The 768 KB Flash capacity is useful for protocol handlers, configuration tables, diagnostics, and application logic. In an industrial design, the MCU would normally process sensor inputs, supervise actuators, manage a CAN network, and report operating data over another interface. The 144-LFBGA 10 x 10 mm footprint saves board area but requires multilayer routing and fine-pitch assembly. Final qualification should verify the operating-temperature grade, electrical limits, isolation boundaries, and long-term component availability.
おすすめ
USB-CAN Network Gateway
The STM32F103ZFH6 is appropriate for a USB-to-CAN gateway that bridges a host computer with embedded equipment. The verified STM32F103 feature set includes USB, CAN, and six communication interfaces, allowing one MCU to manage multiple protocol-facing tasks without relying on a separate interface controller. Its 72 MHz Cortex-M3 core can support concurrent interrupt-driven traffic, while 768 KB Flash provides room for USB and CAN stacks, local configuration, diagnostics, and firmware-update handling. A practical design would isolate the CAN physical layer from the MCU, implement bus protection, and define behavior during bus errors or USB suspend. Before production, validate protocol timing, transceiver requirements, bus termination, firmware latency, and recovery behavior. The MCU package also requires a controlled multilayer PCB with short escape routes from the 144-LFBGA footprint.
おすすめ
Data Acquisition and Sensor Hub
The STM32F103ZFH6 can serve as the control center of a data-acquisition or sensor-hub platform that samples external sensors and forwards measurements. The verified family specification includes two ADCs and six communication interfaces, while the 72 MHz Cortex-M3 core leaves processing capacity for filtering, calibration, status monitoring, and data packaging. Its 768 KB Flash accommodates acquisition firmware, interface drivers, lookup tables, and communication protocols. A typical system would sample supported analog inputs, convert them into engineering units, apply calibration information, and publish results over a serial or network link. Because the supplied data does not state ADC resolution, sample rate, SRAM capacity, or channel count, those limits must be confirmed from the exact datasheet. Board-level implementation should also include input protection, anti-alias filtering, reference-voltage planning, and careful separation between analog and digital signals.
おすすめ
Motor and Motion Control Platform
The STM32F103ZFH6 suits embedded motor-control and motion-control platforms where real-time timing, analog measurement, and serial communication must coexist. Its verified 72 MHz Cortex-M3 core and six timers provide a basis for generating timing references and servicing control interrupts, while the two ADCs support feedback measurements. The 768 KB Flash capacity can hold motion algorithms, parameter tables, communications, and diagnostic functions. A practical implementation would connect the MCU to external power-stage drivers, use timers for deterministic control updates, and sample current or position feedback through supported analog channels. The exact PWM resolution, timer channels, ADC characteristics, and operating-temperature limits are not present in the supplied excerpts and require confirmation from STMicroelectronics documentation. Layout should minimize analog noise, provide stable power and ground distribution, and account for thermal conditions generated by the external motor driver.
おすすめ
USB Embedded Control Device
The STM32F103ZFH6 is well suited to a USB-connected embedded controller because the verified STM32F103 family feature set includes USB, timers, ADCs, and multiple communication interfaces. The 72 MHz ARM Cortex-M3 core can handle USB traffic while running supervisory logic or responding to local controls, and the 768 KB Flash capacity supports device firmware, USB descriptors, configuration data, and application-specific routines. A typical implementation would expose status information, configuration controls, and diagnostic data to a host computer while executing local real-time tasks. The design must account for USB electrical requirements, connector protection, bus or power-supply topology, and enumeration behavior. Exact USB standards, transfer modes, endpoint configuration, and current consumption are not included in the verified excerpts and should be confirmed using the exact manufacturer documentation before schematic approval.
おすすめ
Communication Equipment
The STM32F103ZFH6 can support communication equipment that requires a compact controller with several peripheral resources and a substantial embedded-code allowance. Its verified 72 MHz Cortex-M3 core provides real-time processing, while six communication interfaces, six timers, USB, and CAN support multiple data paths and protocol functions. The 768 KB Flash capacity is suitable for protocol stacks, framing logic, routing tables, diagnostics, and configuration storage. In a communications module, the MCU might manage a local network interface, maintain session or routing information, and coordinate control messages across another serial link. Designers should verify peripheral multiplexing against the 144-LFBGA ball map, check bandwidth and interrupt requirements, and confirm that the selected MCU package can be assembled reliably by the PCB and assembly suppliers. EMI, ESD, thermal performance, and protocol-specific certification remain separate system-level requirements.

設計ノート
Treat the STM32F103ZFH6 as a fine-pitch BGA design rather than a conventional leaded package. Use the official 144-LFBGA 10 x 10 mm land pattern, route all 144 balls on a multilayer PCB, and establish escape-routing geometry before placing decoupling capacitors or sensitive analog components. Maintain consistent via dimensions and spacing according to the PCB fabricator's current capabilities. A paste mask and assembly profile derived from the manufacturer package drawing are essential; dimensions inferred from a generic BGA library can create solder-bridging or open-joint risk.
Place supply and ground decoupling components directly at the associated 144-LFBGA balls using the shortest possible current loops. Separate noisy digital return paths from analog reference and measurement areas, and verify the exact supply pins, voltage tolerances, and decoupling values against the STMicroelectronics datasheet. The verified sources confirm 2.5 V or 3.3 V operation, but they do not provide the complete decoupling network or internal regulator arrangement. Do not copy a generic STM32F1 board without checking the exact package pinout and schematic.
Avoid selecting a replacement from the STM32F103 family by MPN family name alone. The target has 768 KB of Flash in a 144-LFBGA package, while family members may differ in memory density, package, pin availability, temperature grade, and peripheral population. For every proposed alternative, compare the complete ball map, power pins, exposed connections, clock pins, debug interface, USB and CAN resources, ADC channels, and timer assignments. A valid drop-in candidate must preserve the PCB footprint and every connected signal's electrical and protocol behavior.
コンプライアンス情報
