Product Overview

STM32F103CBT6 is a medium-density performance line 32-bit microcontroller from STMicroelectronics, based on the ARM Cortex-M3 core, belonging to the STM32F103xB series. It features an LQFP48 package (7×7mm), 128KB Flash memory, and 20KB SRAM, with a maximum operating frequency of 72MHz. Supporting a wide voltage range of 2.0V to 3.6V, it integrates rich peripherals and low-power modes, suitable for industrial control, motor drives, medical devices, and other scenarios requiring high performance and reliability.

Key Features

• High-Performance Processing：Powered by a 72MHz ARM Cortex-M3 core, supporting single-cycle multiplication and hardware division, with a performance of 1.25 DMIPS/MHz to efficiently run complex control algorithms.
• Adequate Memory：128KB Flash (for program storage) and 20KB SRAM (for data caching), supporting in-system programming. Flash endurance ≥10,000 cycles, data retention for 10 years.
• Rich Peripherals：Including 3×16-bit general-purpose timers, 1×16-bit advanced PWM timer, 2×12-bit ADCs (16 channels, 1µs conversion time), 3×USART, 2×SPI (18Mbit/s), 2×I2C, USB 2.0 full-speed, and CAN 2.0B interfaces, meeting multi-scenario expansion needs.
• Industrial-Grade Reliability：Operating temperature range -40°C to +85°C, 5V tolerant I/Os, and ESD protection up to 2kV (HBM), adapting to harsh industrial environments.
• Low-Power Design：Supports Sleep, Stop, and Standby modes, with Standby current as low as 1.7µA. VBAT pin maintains RTC and backup registers, extending battery life.

Technical Specifications

Typical Applications

• In industrial control systems, STM32F103CBT6 accurately drives stepper motors and actuators with its 72MHz performance and rich timers. The 12-bit ADC enables high-precision sensor data collection, while the CAN interface supports real-time device communication. Its industrial temperature range ensures stable production line operation.
• For portable medical devices (e.g., blood glucose monitors), the low-power mode extends battery life, 128KB Flash stores detection algorithms, the USB interface facilitates data upload, and the 12-bit ADC ensures detection accuracy. The compact LQFP48 package fits small device designs.

Why Choose STM32F103CBT6？

• Powerful Computing Performance：72MHz Cortex-M3 core with hardware division, outperforming 8-bit/16-bit MCUs in real-time control and data processing.
• High Integration：Integrated USB, CAN, and multi-channel ADC reduce external components, simplifying hardware design.
• Industrial-Grade Stability：-40°C to +85°C operating temperature and 2kV ESD protection, suitable for outdoor and factory environments.
• Flexible Power Control：Multiple low-power modes for scenario-specific adjustment, with 1.7µA standby current ideal for battery-powered devices.
• Mature Ecosystem：Compatible with ST standard peripheral libraries and HAL, with rich tools (e.g., STM32CubeIDE) accelerating project development.
