STM32F103CBU6TR - 72MHz Cortex-M3 128KB MCU | STMicroelectronics (Tape & Reel)
MPN: STM32F103CBU6TR ✓ Hoạt độngSTM32F103CBU6TR Tóm tắt
A microcontroller is a programmable semiconductor that integrates a CPU core, memory, peripherals, and interfaces into a single embedded-control component. The STM32F103 belongs to the ARM Cortex-M microcontroller class and the broader embedded-processor hierarchy: MCU, microcontroller, embedded processor, and semiconductor. This device family is intended for systems that need deterministic control, serial communications, analog measurement, and moderate firmware complexity without a separate processor.
Key verified features include a 72 MHz ARM Cortex-M3 CPU, 1.25 DMIPS/MHz Dhrystone 2.1 performance at zero-wait-state memory access, single-cycle multiplication, hardware division, and 128 KB of Flash. The family feature description also identifies USB, CAN, seven timers, two ADCs, and nine communication interfaces. These peripherals support connected industrial controls, USB peripherals, CAN nodes, measurement systems, and compact embedded products.
The STM32F103CBU6TR uses a 48-UFQFPN package with an exposed pad, enabling a compact PCB footprint and improved heat spreading when the pad is properly connected to the ground plane. The MCU is not a power semiconductor, so a safe-operating-area chart is not applicable. Supply voltage, current, temperature limits, pin functions, and detailed electrical limits are not fully included in the supplied verified data and must be confirmed from the manufacturer datasheet before design release.
Typical applications include industrial automation, USB-enabled embedded controls, CAN-connected equipment, motor and motor-control systems, instrumentation, and low-cost development platforms. Its 72 MHz processing rate and communication peripherals make it suitable for control loops that require more performance than a simple 8-bit MCU while retaining a broad embedded peripheral set. The 48-pin package also offers more I/O and interface options than smaller 32-pin or 20-pin devices.
For a new design, preserve the exposed-pad land pattern, follow the manufacturer's decoupling and layout guidance, and verify pin multiplexing, clock configuration, peripheral assignment, and firmware support against the exact datasheet and reference manual. This page combines verified distributor specifications, sourced replacement information, comparison structure, and practical design guidance; it does not substitute for an electrical sign-off of the manufacturer documentation.

Ứng dụng tiêu biểu
STM32F103CBU6TR phù hợp cho 6 Áp dụngs: USB-Enabled Embedded Control, CAN-Connected Industrial Equipment, Industrial Automation Controller, Motor and Motor-Control Systems, Instrumentation and Data Acquisition, Communication Gateway and Protocol Bridge.
USB-Enabled Embedded Control
The STM32F103CBU6TR fits compact USB-connected controllers because the verified family data identifies USB, a 72 MHz ARM Cortex-M3 core, 128 KB Flash, seven timers, and two ADCs. The MCU can manage protocol handling, state machines, control outputs, and sensor acquisition in one device. Its 48-UFQFPN footprint provides more pin options than a low-pin-count controller while keeping the design compact. The main design consideration is USB transceiver and signal-integration planning, together with firmware validation for the exact USB peripheral configuration.
Được đề xuất
CAN-Connected Industrial Equipment
The STM32F103CBU6TR is suitable for CAN-connected industrial equipment because the verified STM32F103 family includes CAN, nine communication interfaces, timers, and ADCs. It can coordinate remote sensors, actuator commands, diagnostic data, and local control loops while retaining 128 KB of Flash for application firmware. The 72 MHz Cortex-M3 core supports responsive protocol and control tasks. Design the CAN transceiver, termination, isolation, and protection network separately, and validate timing against the selected bus topology.
Được đề xuất
Industrial Automation Controller
The STM32F103CBU6TR works as an industrial automation controller when a design needs a 32-bit CPU, 72 MHz performance, USB or CAN communications, two ADCs, and multiple timers. It can execute sequencing logic, monitor analog inputs, drive discrete outputs, and communicate with supervisory equipment. The 48-pin UFQFPN package provides a practical pin count for mixed control and communications. Production designs should follow the manufacturer reference manual for alternate-function mapping, clock setup, reset behavior, decoupling, and exposed-pad implementation.
Được đề xuất
Motor and Motor-Control Systems
The STM32F103CBU6TR can serve in motor-control and embedded motion systems because its Cortex-M3 core reaches 72 MHz and the verified family data identifies seven timers and two ADCs. Timers support precise counting and timing functions, while ADCs can acquire current or position-related analog signals. The MCU can coordinate control algorithms, communication, and protection logic. Power-stage design, gate-drive timing, current sensing, thermal protection, and motor-specific safety requirements remain external to the MCU and must be validated independently.
Được đề xuất
Instrumentation and Data Acquisition
The STM32F103CBU6TR is appropriate for instrumentation and data-acquisition modules requiring two ADCs, nine communication interfaces, 128 KB Flash, and deterministic 72 MHz processing. It can sample analog channels, apply calibration and filtering, execute control logic, and forward results through USB, CAN, or other available serial interfaces. The 48-pin package provides more I/O flexibility for sensor inputs and communication signals. Input filtering, reference design, sensor excitation, calibration storage, and communication isolation should be specified for the final measurement system.
Được đề xuất
Communication Gateway and Protocol Bridge
The STM32F103CBU6TR can act as a compact communication gateway because the verified family data lists USB, CAN, nine communication interfaces, and a 72 MHz Cortex-M3 core. A gateway can translate between local serial links, packet queues, configuration data, and diagnostic messages while using the 128 KB Flash for firmware. The MCU is suitable when real-time protocol handling is needed without a higher-power application processor. For deployment, verify baud-rate support, buffering, timeout behavior, bootloader strategy, and electrical protection on every external communication line.

Ghi chú thiết kế
Reproduce the 48-UFQFPN footprint and exposed-pad land pattern from the exact STM32F103CBU6TR package drawing. Keep the MCU, decoupling capacitors, and any oscillator or reset components close to their associated pins. Route high-current and high-speed communication paths away from sensitive analog inputs, and provide a continuous ground reference. The verified data confirms the 7 mm by 7 mm package and exposed pad but does not provide the complete recommended land pattern.
Before power-up, verify the STM32F103CBU6TR supply-voltage range, decoupling values, regulator startup behavior, and maximum current from the manufacturer datasheet; those electrical values are not present in the supplied verified snippets. Place bulk and local bypass capacitance according to the reference design and check startup margin across temperature. Do not infer supply limits from the 72 MHz CPU specification, since clock rate and operating voltage are separate constraints.
USB and CAN interfaces need deliberate signal-integrity planning. Keep USB traces short, impedance controlled, and referenced to a continuous ground plane; route CAN differential traces with appropriate geometry and terminate according to the network design. Isolate clocks, high-speed edges, switching supplies, and motor-drive return currents from ADC and communication paths. The verified data confirms the presence of USB and CAN but does not provide trace-impedance or timing values.
Thông tin tuân thủ
The supplied verified data does not state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification status. AEC-Q100 is marked not_applicable because no automotive qualification is stated; this is not an automotive qualification claim.
