The exposed thermal pad needs a via stitch to the ground plane on the PCB to pull heat out of the die — without it, continuous operation above 85°C ambient gets tight. The package is compact enough for space-constrained designs like sensor nodes or handheld tools.","metaTitle":"STM32L071KBU3TR ARM Cortex-M0+ MCU, 32 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32L071KBU3TR 32-bit MCU with ARM Cortex-M0+ core at 32 MHz, 128 KB Flash, 20 KB SRAM, 6 KB EEPROM. -40°C to 125°C range, 1.65V-3.6V","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":"Tape & Reel (TR)","RAM Size":"20K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"6K x 8","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"I²C, IrDA, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"23","Core Processor":"ARM® Cortex®-M0+","Package / Case":"32-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 10x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L071","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"32-UFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5590","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/bdf0122ce3763ca70cc9e1606c816ad1.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the difference between STM32L071KBU3 and STM32L071KBU3TR?","answer":"The difference is the shipping medium: the base part number STM32L071KBU3 typically ships in trays or tubes, while the -TR suffix denotes Tape & Reel packaging for automated pick-and-place assembly.
