The internal oscillator and POR/PVD blocks reduce external BOM count in space-constrained designs. ## 64-LQFP footprint and I/O count — board-level fit The STM32F1 series remains a mainstream offering from ST, with ongoing manufacturing and distributor support. No last-time-buy window to track.","metaTitle":"STM32F103RBT7 STM32F1 MCU, ARM Cortex-M3 72MHz, 128KB Flash","metaDescription":"STM32F103RBT7 32-bit MCU with ARM Cortex-M3 core at 72MHz, 128KB Flash, 20K x 8 RAM, 51 I/O, industrial temp -40°C to 105°C.","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":"Tray","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":"51","Core Processor":"ARM® Cortex®-M3","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b","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 ~ 105°C (TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.0300","priceTiers":[{"qty":1,"price":"$8.03000","currency":"USD"},{"qty":10,"price":"$7.25300","currency":"USD"},{"qty":25,"price":"$6.91600","currency":"USD"},{"qty":160,"price":"$6.00519","currency":"USD"},{"qty":320,"price":"$5.73528","currency":"USD"},{"qty":480,"price":"$5.22925","currency":"USD"},{"qty":960,"price":"$4.55450","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e403fd08f0c2904ac3d150bb82307457.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F103RBT7/alternatives.json"},"ai":{"faq":[{"question":"How does STM32F103RBT7 compare to the STM32L151CBU6A?","answer":"The STM32F103RBT7 offers higher performance and wider temperature coverage, while the series targets battery-operated applications with lower active current.
