STM32F103R6H6A - 72MHz Cortex-M3 32KB MCU | STMicroelectronics
MPN： STM32F103R6H6A ✓ 啟用中STM32F103R6H6A 概覽
An ARM Cortex-M3 microcontroller is a 32-bit RISC embedded processor designed for control-oriented products. In the product hierarchy, the STM32F103R6H6A is a microcontroller, semiconductor, and programmable control component. It executes firmware from embedded Flash while using peripherals for digital interfaces, analog measurement, timers, communications, and general-purpose input/output, making it suitable for compact industrial, communications, and consumer-control designs.
The principal performance figures are a 72 MHz maximum core frequency, 90 DMIPS processing capability, 32 KB of Flash, and 37 I/O ports. The MCU also provides USB and CAN interfaces, two ADCs, and a timer set described in the available product information. These resources allow one device to coordinate data acquisition, protocol handling, timing, and actuator or digital-output control without requiring several separate interface ICs.
The STM32F103R6H6A uses a single-cycle ARM Cortex-M3 core architecture with embedded high-speed memory and an extended I/O set. Its 64-TFBGA package measures 5 x 5 mm and uses a 0.5 mm pitch according to the available package description. The small land pattern supports compact assemblies, but its fine pitch and exposed thermal and routing requirements make careful PCB layout, via placement, and assembly-process verification important.
Typical applications include USB-connected data-acquisition equipment, CAN-connected industrial controllers, compact motor-control systems, sensor-hub products, and low-cost embedded control boards. The 37 I/O ports support discrete digital interfaces, while the two ADCs suit analog sensor conditioning and the CAN and USB interfaces support connected equipment. A specific firmware design should confirm interrupt allocation, peripheral multiplexing, and communication bandwidth before release.
Designers should verify the 2 V to 3.6 V operating range, clock configuration, flash wait-state requirements, decoupling, and exposed-pad thermal layout against the manufacturer datasheet. The verified distributor information does not provide the complete 64-pin assignment, so no pinout should be inferred solely from the package name. Prototype firmware should also be tested for peripheral conflicts and USB or CAN bus timing.
This product record combines verified manufacturer and distributor specifications, current pricing as of 2026-10-30, package information, and practical design guidance. It distinguishes verified drop-in alternatives from package variants and flags parameters that remain unavailable instead of presenting guessed electrical or pin-level data as fact.

典型應用
STM32F103R6H6A 適用於 6 應用s: USB Data-Acquisition Controller, CAN-Connected Industrial Controller, Compact Motor-Control System, Sensor and Condition Monitoring Hub, Embedded Communications Module, Low-Cost Embedded Control Board.
USB Data-Acquisition Controller
The STM32F103R6H6A fits a compact USB data-acquisition controller because its verified feature set combines a 72 MHz Arm Cortex-M3 core, 32 KB Flash, 37 I/O ports, two ADCs, and a USB interface. The MCU can sample connected analog channels, apply digital filtering and calibration, and present results through USB while coordinating discrete inputs and outputs. Its 64-TFBGA 5 x 5 mm package reduces board area in instruments where USB is the primary host connection. Firmware must verify USB clock requirements and peripheral pin multiplexing before production release.
推薦
CAN-Connected Industrial Controller
The STM32F103R6H6A is suitable for a compact industrial controller because the verified specifications include CAN, 37 I/O ports, two ADCs, and a 72 MHz Cortex-M3 processing core. Firmware can acquire sensor data, execute control logic, monitor digital interlocks, and exchange state or diagnostic information over CAN. The 2 V to 3.6 V operating range supports 3.3 V system rails. For deployment, the design must implement proper CAN-bus termination, protection, grounding, and fault handling, while confirming the exact transceiver and connector selected for the product.
推薦
Compact Motor-Control System
The STM32F103R6H6A can serve as the control processor in a compact motor-control system because the MCU provides a 72 MHz Cortex-M3 core, multiple timers, two ADCs, and 37 I/O ports. PWM outputs can command motor drivers, while the ADC channels can monitor position, current, or temperature signals when their analog functions are assigned correctly. Its small 64-TFBGA package allows a compact controller, although 0.5 mm pitch raises assembly complexity. Firmware must confirm timer channels, ADC sampling requirements, and safe-state behavior for power stages before driving a motor.
推薦
Sensor and Condition Monitoring Hub
The STM32F103R6H6A suits a sensor-hub or condition-monitoring product because its two ADCs, 37 I/O ports, and 72 MHz Cortex-M3 core allow it to combine analog measurements with digital status inputs in one controller. The MCU can sample sensors, perform filtering, track thresholds, and communicate measurements through USB or CAN. Operating from 2 V to 3.6 V supports integration into 3.3 V embedded systems. Signal-chain design should allocate ADC pins according to the verified alternate-function mapping, provide suitable reference and filtering components, and isolate noisy switching nodes from analog inputs.
推薦
Embedded Communications Module
The STM32F103R6H6A can support a compact communications module because the verified MCU combines USB, CAN, a 72 MHz Cortex-M3 core, 32 KB Flash, and 37 I/O ports in a 5 x 5 mm package. This permits protocol processing, status monitoring, and local control in a small module without an external microprocessor. The 2 V to 3.6 V supply range is appropriate for a 3.3 V rail. Production firmware should validate USB or CAN timing, configure the required clock tree, and include watchdog recovery and bus fault handling appropriate to the communication protocol.
推薦
Low-Cost Embedded Control Board
The STM32F103R6H6A is appropriate for a cost-conscious embedded control board requiring a 72 MHz Arm Cortex-M3 core, 32 KB Flash, 37 I/O ports, USB, CAN, and two ADCs. The MCU can coordinate user interfaces, sensors, communication ports, and routine automation tasks while operating from a 2 V to 3.6 V supply. The 64-TFBGA 5 x 5 mm package supports space-constrained boards, but the fine 0.5 mm pitch may increase assembly cost compared with leaded packages. Prototype validation should cover thermal performance, USB enumeration, CAN timing, and firmware peripheral conflicts.

主要差異化特點
- Compact 64-TFBGA implementation (對比STM32F103R6T6A)

- Higher verified processing capability (對比ATMEGA328P-MNR)
設計說明
Use the official STM32F103R6H6A 64-TFBGA land pattern rather than adapting a drawing for another STM32F103 suffix. The verified package is 5 x 5 mm with 0.5 mm pitch, so alignment, solder-paste volume, and assembly capability should be reviewed before fabrication. Place decoupling components close to the appropriate supply pins, preserve the package-exposed-pad connection specified by STMicroelectronics, and route high-current and high-speed signals away from sensitive analog inputs.
Design the supply around the verified 2 V to 3.6 V operating range and confirm all voltage-dependent limits in the manufacturer datasheet. Decouple the MCU supply locally and use separate filtering paths for analog inputs when sensitive measurements are required. USB transceiver, CAN transceiver, and attached peripherals may add voltage and current requirements not described by the MCU listing, so the regulator and power-distribution network should be sized for the complete board rather than the 72 MHz core frequency alone.
Keep the 16 MHz clock path and ADC-related routing short and controlled because the STM32F103R6H6A combines a 72 MHz processing core with two ADCs and numerous multiplexed I/O functions. Avoid routing sensitive analog traces beneath or beside digital clock and switching nets, provide a clean analog reference strategy, and verify alternate-function assignments in the device pin table. Complete pin-level layout cannot be finalized from the verified search snippets because the authoritative 64-pin assignment was not supplied.
Do not assume that STM32F103R6T6A, STM32F103R6T6ATR, or a GD32F103-family device is a mechanical drop-in replacement for this H6A order code. The verified H6A listing specifies 64-TFBGA 5 x 5 mm, and related suffix variants may use different land patterns. Verify package drawings, pin names, exposed-pad requirements, clock behavior, flash configuration, peripheral differences, and firmware dependencies before substituting any part. Migration also requires board and software regression testing.
合規資訊
RoHS compliance is explicitly identified in the verified part listing. REACH, AEC-Q100, lead-free, halogen-free, and conflict-minerals status were not supplied and remain unknown.
