For existing BOMs, sourcing this exact code now depends on inventory held by independent distributors; we can quote current availability and pricing against an RFQ. ## Peripheral fit — CAN and USB on a 32 KB part The CAN interface makes this MCU a natural fit for a compact CAN node in an industrial or automotive sub-system where the firmware is lean enough to fit in 32 KB. The USB peripheral (device mode) can serve as a simple data-logger or configuration port. The 10 KB RAM (10K x 8) is the tightest in the STM32F103R line — any DMA transfer or USB buffer allocation must be planned against that ceiling. The 16-channel 12-bit ADC covers multi-sensor acquisition without an external mux. ## Firmware bring-up note — flash wait state at 72 MHz At 72 MHz the internal Flash requires at least one wait state for reliable zero-wait execution. The bootloader defaults to a lower clock; the application code must configure the flash latency register before raising the PLL to full speed, or the first branch will hard-fault. The SWD debug port stays alive even with the independent watchdog enabled, which helps during early bring-up.","metaTitle":"ST STM32F103R6T6 ARM Cortex-M3 MCU, 72 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32F103R6T6 32-bit ARM Cortex-M3 MCU, 72 MHz, 32 KB Flash, 10 KB RAM, CAN/USB, -40°C to 85°C, 64-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"72MHz","Series":"STM32F1","Package":"Tray","RAM Size":"10K 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-LQFP","Product Status":"Obsolete","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F103","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Voltage - Supply (Vcc/Vdd)":"2V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.8900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/42f02f89944e6df7814fe7b7034b92e2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F103R6T6/alternatives.json"},"ai":{"faq":[{"question":"Is STM32F103R6T6 obsolete?","answer":"Yes, the STM32F103R6T6 is listed as Obsolete.
