Not a hand-solder or rework-friendly part; plan for a proper reflow profile and a clean PCB surface finish (ENIG or OSP). ## Supply voltage and power management The built-in POR/PVD/PDR circuits handle brown-out detection and power-on reset without an external supervisor — one less BOM line. The internal oscillator can serve as the system clock, though for CAN or USB operation an external crystal is recommended for accuracy. ST's product status for the STM32F103RDY6TR is Active.","metaTitle":"STMicroelectronics STM32F103RDY6TR ARM Cortex-M3 MCU, 72 MHz","metaDescription":"STM32F103RDY6TR: 32-bit ARM Cortex-M3 MCU at 72 MHz with 384 KB Flash, 64 KB SRAM, CAN, USB, motor control PWM, in 64-WLCSP.","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, 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-UFBGA, WLCSP","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F103","Program Memory Size":"384KB (384K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"64-WLCSP (4.47×4.4)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.6100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/72e2217711e2aa33719949448f146656.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F103RDY6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM32F103RDY6TR?","answer":"Within the STM32F103 series, the 64-pin WLCSP variants share the same footprint and pinout across the density options (64 KB to 512 KB Flash).
