The STM32F105R8T6TR is an active product with no last-time-buy notice. The 64-LQFP package is shared across the STM32F105 series, allowing a BOM swap to a higher-density variant without a PCB change. ## Package and mounting — the 64-LQFP footprint The 51 available I/O lines are distributed across the four sides of the package; pay attention to the supply pin pairs (VDD/VSS) when laying out the decoupling — the datasheet recommends a 100 nF ceramic per pair plus a bulk capacitor on the main 3.3 V rail.","metaTitle":"STM32F105R8T6TR STM32F1 ARM Cortex-M3 MCU, 72 MHz","metaDescription":"STMicroelectronics STM32F105R8T6TR 32-bit ARM Cortex-M3 MCU at 72 MHz with 64 KB Flash, 64 KB SRAM, USB OTG, CAN, 51 I/O, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"72MHz","Series":"STM32F1","Package":"Tape & Reel (TR) Cut Tape (CT)","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, POR, PWM, Voltage Detect, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, SPI, UART/USART, USB OTG","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":"STM32F105","Program Memory Size":"64KB (64K 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":"$6.6600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/813271393bd0544f247ae965ea1bf2b0.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F105R8T6TR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F105R8T6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F105R8T6TR when reusing this data.
