If your application streams audio or holds large lookup tables, you will be budgeting bytes. The DMA controller offloads peripheral-to-memory transfers without CPU intervention, which helps keep real-time loops tight. The motor-control PWM timer with complementary outputs and programmable dead time is a genuine differentiator — this part was designed with BLDC and PMSM drive in mind, not just general-purpose control. ## 64-TFBGA — what the package means for layout and procurement The 64-TFBGA (5x5 mm) is a 0.5 mm pitch BGA. It saves roughly 40% board area versus the equivalent LQFP-64, but it requires micro-via or blind-via PCB technology for fanout, and rework needs a BGA station. If your production line is set up for QFP only, the pin-compatible STM32F103RBT6 in LQFP-64 is the easier assembly choice — but the BGA version gives you a smaller footprint if board space is the constraint. That said, the STM32F1 is a mature platform — ST's roadmap emphasis has shifted to the STM32G0, G4, and H5 series. For new designs, consider whether the STM32F103RBH6TR's peripheral mix and BGA package still match your long-term supply strategy. For existing BOM lines, the active status means you can order through normal distribution without broker premiums.","metaTitle":"STM32F103RBH6TR ARM Cortex-M3 MCU, 72 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32F103RBH6TR 32-bit MCU with 72 MHz ARM Cortex-M3 core, 128 KB Flash, 20 KB RAM, 51 I/O, CAN/USB/SPI/I²C, -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":"Tape & Reel (TR)","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":"128KB (128K 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":"$4.3017","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ee18814be9a61431b80fb87c2c23e468.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F103RBH6TR/alternatives.json"},"ai":{"faq":[{"question":"Can STM32F103RBH6TR replace STM32F103RBT6?","answer":"The STM32F103RBT6 is the LQFP-64 variant of the same die — same 72 MHz Cortex-M3 core, same 128 KB Flash and 20 KB RAM.
