The pad needs a good via stitch to the ground plane to pull heat out; without it the junction temperature climbs fast under continuous load. The small pitch and no leads mean the reflow profile wants a tight soak zone — too fast a ramp and you get head-in-pillow joints. Orientation mark is pin 1 chamfer on the top-left corner, easy to spot under a microscope. Will it survive the hot air? Yes, if you preheat the board to 100°C and use a nozzle that covers the whole body, not a tiny pencil tip. ## Peripherals and connectivity On the peripheral side you get I²C, SPI, UART/USART, USB, and IrDA, plus a 13-channel 12-bit ADC and a 2-channel 12-bit DAC. With 40 I/O in a 48-pin package, most of the pins are usable — good for a design that needs a few buttons, an LCD segment driver, and a sensor interface without a port expander.","metaTitle":"STM32L072CBU6 ARM Cortex-M0+ MCU, 32 MHz, 128 KB Flash","metaDescription":"STM32L072CBU6 is a 32-bit ARM Cortex-M0+ MCU from STMicroelectronics, 32 MHz, 128 KB Flash, 20 KB SRAM, 6 KB EEPROM, 40 I/O, 1.65-3.6 V, -40 to 85°C, in","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"32MHz","Series":"STM32L0","Package":"Tray","RAM Size":"20K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"6K x 8","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, SPI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"40","Core Processor":"ARM® Cortex®-M0+","Package / Case":"48-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 13x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L072","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"48-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.2985","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ada4f80ea4bd20d880045c15cfc2cc1e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between STM32L072CBU6 and STM32L073CBU6?","answer":"The STM32L073CBU6 is the higher-density sibling in the same package and pinout. It doubles the Flash to 192 KB and adds a few more peripheral features (e.g., additional comparators and capacitive sensing channels). For designs that need more code space or extra analog blocks, the L073 is the step-up; the L072 covers the 128 KB tier with the same core and supply range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L072CBU6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L072CBU6 when reusing this data.
