For applications that need the M3 pipeline and peripheral set but don't need 72 MHz throughput — sensor hubs, simple motor controls, human-machine interfaces — this part fits without paying for unused clock headroom. ## Peripheral set and connectivity — what's available on the bus The peripheral list includes DMA, PDR, POR, PVD, PWM, a temperature sensor, and a watchdog timer. The 16-channel 12-bit ADC (A/D 16x12b) handles analog sensor inputs without an external converter. The Vcc range of 2V to 3.6V lets the MCU run directly from two alkaline cells or a shared 3.3V rail without a separate LDO. The lifecycle status is listed as Active. The base product number STM32F101 anchors the family, so die revisions or errata updates would roll under the same ordering code. ## Sourcing posture — quoted to order on the spot market No stock-count or lead-time figure is published here because the supply picture changes weekly — a direct RFQ returns the real-time position.","metaTitle":"STM32F101RBT6TR ARM Cortex-M3 MCU, 36 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32F101RBT6TR 32-bit MCU, 36 MHz, 128 KB Flash, 16 KB RAM, 51 I/O, -40 to 85°C, 64-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"36MHz","Series":"STM32F1","Package":"Tape & Reel (TR) Cut Tape (CT)","RAM Size":"16K 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","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F101","Program Memory Size":"128KB (128K 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":"$6.5000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/605d138a68c44da9433402f3eee154b1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F101RBT6TR/alternatives.json"},"ai":{"faq":[{"question":"Is STM32F101RBT6TR pin compatible with STM32F103RBT6?","answer":"Yes, the STM32F101RBT6TR and STM32F103RBT6 share the same 64-LQFP pinout. The two parts are footprint-identical on the board. The difference is the core clock — the F103 runs at 72 MHz while the F101 is limited to 36 MHz — and the F103 adds a second ADC and a USB interface that the F101 omits. If your firmware and peripheral requirements fit within the F101's resources, it drops straight into the same PCB layout as a cost-reduced alternative."},{"question":"What is the closest pin-compatible alternative to STM32F101RBT6TR in this family?","answer":"The STM32F103RBT6 is the direct pin-compatible upgrade. Same 64-LQFP footprint and same 128 KB Flash / 16 KB RAM, but the F103 doubles the core clock to 72 MHz and adds a second 12-bit ADC plus USB 2.0 full-speed. If your design needs the extra throughput or USB connectivity, the F103 swaps in without a PCB change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F101RBT6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F101RBT6TR when reusing this data.
