It integrates motor control PWM timers, DMA, a 12-bit ADC with 16 channels, a 12-bit DAC with 2 channels, and connectivity for CANbus, USB, I²C, SPI, and multiple UART/USART interfaces. ## 72 MHz core and 96 KB SRAM — headroom for real-time control loops The 72 MHz Cortex-M3 core delivers 1.25 DMIPS/MHz, enough for sensor fusion or field-oriented motor control loops without external DSP. The 96 KB SRAM supports dual CAN message buffers, a USB packet buffer, and a modest RTOS heap simultaneously. ## Motor control PWM and CAN — built for drive and industrial bus nodes The peripheral set includes advanced motor control PWM timers with dead-time insertion and complementary outputs, plus a CAN 2.0B interface. This combination makes the STM32F103RFT6TR a direct fit for brushless DC (BLDC) and permanent-magnet synchronous motor (PMSM) drives, as well as CANopen fieldbus nodes. The base product number is STM32F103, which shares pin-compatibility across the STM32F103 value-line density options — a 256 KB or 512 KB Flash sibling can serve as a drop-in substitute if the full 768 KB is not needed, though the firmware image must fit the smaller memory. ## Sourcing note: TR suffix is Tape & Reel, same die as the tray variant The die and firmware are identical to the tray-packaged STM32F103RFT6. If your BOM specifies the tray variant, this TR version is a direct substitute — same footprint, same electricals, same programming algorithm.","metaTitle":"STM32F103RFT6TR STM32F1 MCU, 72 MHz, 768 KB Flash, 64-LQFP","metaDescription":"STMicroelectronics STM32F103RFT6TR ARM Cortex-M3 MCU, 72 MHz, 768 KB Flash, 96 KB SRAM, 51 I/O, -40 to 85°C, 64-LQFP.","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":"96K 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":"51","Core Processor":"ARM® Cortex®-M3","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F103","Program Memory Size":"768KB (768K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.9300","priceTiers":[{"qty":1,"price":"$10.93000","currency":"USD"},{"qty":10,"price":"$10.04200","currency":"USD"},{"qty":25,"price":"$9.62600","currency":"USD"},{"qty":100,"price":"$8.48140","currency":"USD"},{"qty":250,"price":"$8.06516","currency":"USD"},{"qty":500,"price":"$7.54482","currency":"USD"},{"qty":1000,"price":"$6.92041","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1e0a2899638e8adeb34943c703bd9a9b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F103RFT6TR/alternatives.json"},"ai":{"faq":[{"question":"Is STM32F103RFT6TR obsolete?","answer":"ST continues to manufacture it; there is no announced last-time-buy or end-of-life notice."},{"question":"What is the difference between STM32F103RFT6 and STM32F103RFT6TR?","answer":"The die and electrical specifications are identical.
