For a typical motor-control or sensor-fusion firmware stack, 256 KB holds the application code plus a bootloader with room for OTA staging; 32 KB of RAM supports moderate-sized lookup tables, communication buffers, and real-time control variables. If the design needs more than 32 KB of volatile data — for example, a large frame buffer or extensive logging — this part will hit the ceiling, and the 72 MHz STM32F103 sibling with matching Flash but identical RAM won't help; you would step to a higher-density STM32F1 or F4 variant. STMicroelectronics lists the STM32F101RCT6TR as Active. For production planning, that means no forced redesign window; the part can be qualified into a new BOM today with confidence that the supply channel will remain open through the typical product lifecycle. The ROHS3 compliance covers EU regulatory requirements without exemption paperwork. ## Package and footprint — 64-LQFP, 10x10 mm Housed in a 64-lead LQFP with a 10x10 mm body, the STM32F101RCT6TR uses a fine-pitch 0.5 mm lead pitch. Cut Tape (CT) is also available for prototype or low-volume builds. The DMA controller offloads data transfers from the CPU, which matters at 36 MHz when servicing multiple high-rate peripherals simultaneously.","metaTitle":"STM32F101RCT6TR STM32F1 MCU, 36 MHz, 256 KB Flash, 64-LQFP","metaDescription":"STMicroelectronics STM32F101RCT6TR ARM Cortex-M3 MCU, 36 MHz, 256 KB Flash, 32K x 8 RAM, 51 I/O, -40°C 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":"36MHz","Series":"STM32F1","Package":"Tape & Reel (TR) Cut Tape (CT)","RAM Size":"32K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, PDR, POR, PVD, PWM, Temp Sensor, WDT","Connectivity":"I²C, IrDA, LINbus, SPI, UART/USART","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":"STM32F101","Program Memory Size":"256KB (256K 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":"$7.6200","priceTiers":[{"qty":1,"price":"$7.62000","currency":"USD"},{"qty":10,"price":"$6.88000","currency":"USD"},{"qty":25,"price":"$6.56000","currency":"USD"},{"qty":100,"price":"$5.69610","currency":"USD"},{"qty":250,"price":"$5.44016","currency":"USD"},{"qty":500,"price":"$4.96014","currency":"USD"},{"qty":1000,"price":"$4.32011","currency":"USD"},{"qty":2000,"price":"$4.16011","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/fbf302d4f0db56efe66035db5e3aaeca.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F101RCT6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F101RCT6TR and STM32F103RCT6?","answer":"The key difference is core speed: the STM32F101RCT6TR runs at 36 MHz, while the STM32F103RCT6 runs at 72 MHz.
