The 36-VFQFPN package (6x6 mm) with exposed pad keeps the board area tight while the pad handles thermal dissipation at continuous loads. At 72 MHz the Cortex-M3 executes most single-cycle instructions, so a tight motor-control PWM loop or a USB packet handler runs without stalling the core. The 128 KB Flash needs one wait state above 48 MHz — the hardware handles it transparently once the clock tree is configured. The 20 KB SRAM is enough for moderate buffering; if your application queues large CAN messages or USB bulk transfers, budget the RAM before committing. ## Peripherals and connectivity — what is on the 26 I/O The part includes DMA, a motor-control PWM timer, a temperature sensor, and a watchdog, plus CAN, USB, I²C, SPI, and up to three USARTs with IrDA and LIN support. The 10-channel 12-bit ADC covers analog inputs. With 26 I/O in a 36-pin package, most pins are shared — the peripheral multiplexer needs careful allocation during pinout planning. ## Industrial temperature grade — where it runs It is not qualified for automotive under-hood (no AEC-Q100 in the record), but the industrial range covers most panel-mount and enclosure-based equipment.","metaTitle":"STM32F103TBU6TR STM32F1 MCU, 72 MHz, 128 KB Flash, 36-VFQFPN","metaDescription":"STM32F103TBU6TR 32-bit ARM Cortex-M3 MCU, 72 MHz, 128 KB Flash, 20 KB SRAM, industrial temp -40°C to 85°C, 36-VFQFPN.","metaKeywords":null},"attributes":{"series":"STM32F1","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"72MHz","Series":"STM32F1","Package":"Tape & Reel (TR) Cut Tape (CT)","RAM Size":"20K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, Motor Control PWM, PDR, POR, PVD, PWM, Temp Sensor, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"26","Core Processor":"ARM® Cortex®-M3","Package / Case":"36-VFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 10x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F103","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"36-VFQFPN (6x6)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.0400","priceTiers":[{"qty":1,"price":"$7.04000","currency":"USD"},{"qty":10,"price":"$6.35600","currency":"USD"},{"qty":25,"price":"$6.06000","currency":"USD"},{"qty":100,"price":"$5.26200","currency":"USD"},{"qty":250,"price":"$5.02548","currency":"USD"},{"qty":500,"price":"$4.58206","currency":"USD"},{"qty":1000,"price":"$3.99083","currency":"USD"},{"qty":3000,"price":"$3.84302","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/b951295a5a701632768131870cfc7618.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F103TBU6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F103TBU6 and STM32F103TBU6TR?","answer":"The STM32F103TBU6 and STM32F103TBU6TR are the same silicon.
