The 16 KB SRAM (organized as 16K x 8) handles a couple of 1 KB DMA buffers plus the stack and heap — if you are doing heavy audio or graphics frame buffering, you will bump the ceiling. The 48 MHz PLL needs one flash wait state above 24 MHz; the hardware prefetch helps keep tight loops running without stalling. ## 49-WLCSP — board-level reality for the rework bench No exposed pad to stitch — thermal dissipation goes through the balls into the PCB copper. On the rework bench, hot-air station with a fine nozzle and a preheat plate below the board; do not pry — the die is the package, and the balls shear before the silicon gives. ## Peripherals and connectivity — what the 37 I/O give you With 37 I/O on a 49-ball package, the pinout is dense. The peripheral set includes a DMA controller, I²S audio interface, POR/PWM timers, and a watchdog. The USB peripheral has its own 48 MHz oscillator sourced from the internal PLL — no external crystal needed for USB if the clock trimming is within tolerance. The 10-channel 12-bit ADC samples up to 1 MSps; the two 12-bit DAC channels are useful for analog set-point generation or audio output. ROHS3 compliant. The base product number is STM32F072, so PCNs and errata are tracked under that family umbrella.","metaTitle":"STM32F072CBY6TR STM32F0 MCU, 48 MHz, 128 KB Flash, 49-WLCSP","metaDescription":"STMicroelectronics STM32F072CBY6TR 32-bit ARM Cortex-M0 MCU at 48 MHz with 128 KB Flash, 16 KB SRAM, USB, CAN, 12-bit ADC/DAC.","metaKeywords":null},"attributes":{"series":"STM32F0","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"48MHz","Series":"STM32F0","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"16K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"DMA, I²S, POR, PWM, WDT","Connectivity":"CANbus, HDMI-CEC, I²C, IrDA, LINbus, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"37","Core Processor":"ARM® Cortex®-M0","Package / Case":"49-UFBGA, WLCSP","Product Status":"Active","Data Converters":"A/D 10x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F072","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"49-WLCSP","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.8600","priceTiers":[{"qty":1,"price":"$5.86000","currency":"USD"},{"qty":10,"price":"$5.26100","currency":"USD"},{"qty":25,"price":"$4.97360","currency":"USD"},{"qty":100,"price":"$4.31040","currency":"USD"},{"qty":250,"price":"$4.08932","currency":"USD"},{"qty":500,"price":"$3.66934","currency":"USD"},{"qty":1000,"price":"$3.09463","currency":"USD"},{"qty":2500,"price":"$3.01425","currency":"USD"},{"qty":5000,"price":"$3.01425","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/842c0bddc0ad2bfac87b7ea526219400.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F072CBY6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F072CBY6TR and STM32F072C8T6?","answer":"The WLCSP saves board area but requires a reflow-capable assembly process; the LQFP is easier to hand-solder and rework.
