The BGA requires via-in-pad or microvia routing for the centre balls; plan for a four-layer stack-up if the full I/O count is used. ## 12-bit ADC for analog sensing Sixteen 12-bit ADC channels are integrated for current-sense resistor monitoring, thermistor inputs, or potentiometer feedback — common in motor-drive current loops and human-machine interface knobs.","metaTitle":"STM32F103R8H6 ARM Cortex-M3 MCU, 72 MHz, 64 KB Flash","metaDescription":"STMicroelectronics STM32F103R8H6 32-bit ARM Cortex-M3 MCU, 72 MHz core, 64 KB Flash, 20 KB SRAM, CANbus, 51 I/O, -40 to 85°C, 64-TFBGA.","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":"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-TFBGA","Product Status":"Active","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F103","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-TFBGA (5x5)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.1066","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/638a51de4b49a357eed482a06ba20b03.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F103R8H6/alternatives.json"},"ai":{"faq":[{"question":"Does STM32F103R8H6 have CAN bus?","answer":"Yes, the STM32F103R8H6 includes a CANbus (Controller Area Network) interface, making it suitable for automotive and industrial fieldbus applications."},{"question":"What is the maximum operating frequency of STM32F103R8H6?","answer":"The core runs at 72 MHz maximum, which places it in the mid-range of the Cortex-M3 performance tier — enough for real-time motor control loops and protocol handling without external RAM."},{"question":"What is the closest pin-compatible alternative to STM32F103R8H6 in this family?","answer":"However, the STM32F103R8H6 uses a 64-TFBGA package, so pin compatibility applies only to the BGA variant; verify the package before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32F103R8H6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32F103R8H6 when reusing this data.
