ST lists the STM32L072KBU6 as Active. The STM32L0 family is ST's mainstream ultra-low-power series, so volume allocation and lead times are generally stable through authorized channels.","metaTitle":"STM32L072KBU6 ARM Cortex-M0+ MCU, 32 MHz, 128 KB Flash","metaDescription":"STMicroelectronics STM32L072KBU6 32-bit MCU with 32 MHz ARM Cortex-M0+, 128 KB Flash, 20 KB SRAM, 6 KB EEPROM, USB, industrial temp -40 to 85°C.","metaKeywords":null},"attributes":{"series":"STM32L0","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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":"23","Core Processor":"ARM® Cortex®-M0+","Package / Case":"32-UFQFN Exposed Pad","Product Status":"Active","Data Converters":"A/D 10x12b; 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":"32-UFQFPN (5x5)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.9200","priceTiers":[{"qty":1,"price":"$4.92000","currency":"USD"},{"qty":10,"price":"$4.41900","currency":"USD"},{"qty":25,"price":"$4.17720","currency":"USD"},{"qty":80,"price":"$3.62038","currency":"USD"},{"qty":230,"price":"$3.43470","currency":"USD"},{"qty":440,"price":"$3.08193","currency":"USD"},{"qty":945,"price":"$2.59922","currency":"USD"},{"qty":2940,"price":"$2.46926","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/67cb9094f3e6522ca004c703798dd6eb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L072KBU6/alternatives.json"},"ai":{"faq":[{"question":"Is STM32L072KBU6 compatible with STM32L072KBU6TR?","answer":"The 'TR' suffix typically denotes tape-and-reel packaging; the silicon and firmware are identical.
