ST lists the STM32L081CBT6TR as Active (current production). The base product number STM32L081 covers multiple package and temperature variants; the CBT6TR suffix confirms the 48-LQFP, -40°C to 85°C grade, and Tape & Reel shipping format.","metaTitle":"STM32L081CBT6TR STMicroelectronics ARM Cortex-M0+ MCU","metaDescription":"STM32L081CBT6TR is a 32-bit ARM Cortex-M0+ MCU from STMicroelectronics, 32 MHz, 128 KB Flash, 20 KB RAM, 6 KB EEPROM, 1.65 V to 3.6 V supply, -40°C to 85°C.","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, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"40","Core Processor":"ARM® Cortex®-M0+","Package / Case":"48-LQFP","Product Status":"Active","Data Converters":"A/D 13x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L081","Program Memory Size":"128KB (128K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5042","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8143764d90fbf45beb08d071cbbf1b30.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How many UART/USART interfaces does STM32L081CBT6TR support?","answer":"The connectivity block includes UART/USART, I²C, SPI, IrDA, and LINbus.
