Product details
The STM32F103CBU6TR from STMicroelectronics sets new standards in Embedded - Microcontrollers for building automation systems. Its multi-protocol wireless capabilities and ultra-low power architecture make it perfect for smart HVAC controls and IoT-enabled lighting systems.Featuring ARM® Cortex®-M3 technology, this microcontroller executes building control algorithms while consuming just 15 A/MHz in active mode.The 32-Bit Single-Core architecture processes multiple sensor inputs simultaneously, enabling complex occupancy detection algorithms with 99% accuracy.Operating at 72MHz, the device maintains sub-millisecond response times for critical safety systems like smoke detection and emergency lighting control.With CANbus, I²C, IrDA, LINbus, SPI, UART/USART, USB support, the microcontroller seamlessly bridges between wired BACnet and wireless Zigbee networks in hybrid building automation systems.Integrated DMA, Motor Control PWM, PDR, POR, PVD, PWM, Temp Sensor, WDT include precision temperature sensors and humidity measurement circuits that eliminate external components in climate control applications.37 configurable interfaces support both digital control signals and analog sensor inputs common in building management panels.128KB (128K x 8) accommodates complete KNX and DALI protocol stacks alongside application code for lighting control scenarios.The FLASH implementation enables secure over-the-air updates for field upgrades without physical access to installed devices.20K x 8 of retention memory preserves system state during power outages, ensuring immediate recovery in critical life safety systems.The 2V ~ 3.6V range supports direct operation from 4-20mA current loops commonly used in building automation sensors.Precision A/D 10x12b achieve 0.5 C accuracy in temperature measurement for precise climate control in sensitive environments.The Internal maintains timing accuracy during battery operation, enabling 10-year operation from a single coin cell in wireless sensors.Rated for -40°C ~ 85°C (TA), the device operates reliably in unconditioned spaces like attics and mechanical rooms.Surface Mount packaging withstands vibration and mechanical stress encountered in HVAC equipment installations.The 48-UFQFN Exposed Pad provides enhanced ESD protection for reliable operation in electrically noisy building environments.Available in 48-UFQFPN (7x7), the microcontroller is pre-certified for global building automation standards including EN 14908.
