This eliminates the cost and board area of an external serial EEPROM in many designs. ## Active lifecycle — no LTB planning needed The part is ROHS3 compliant. The 1.65 V minimum supply is the key spec for single-cell battery operation: a fresh alkaline cell at 1.65 V is essentially empty, so the MCU keeps running until the battery is truly drained. If your application needs the full -40 to 125°C automotive range, this part is not that — it is the industrial-grade sibling in the STM32L0 family. ## Package and I/O — 64-LQFP with 51 usable pins Of the 64 pins, 51 are general-purpose I/O, giving a high pin-to-package ratio. The remaining pins are power, ground, and a few dedicated functions (oscillator, reset, debug). The 16-channel 12-bit ADC is available on many of those I/O pins, so a multi-sensor node can read analog signals without external multiplexers.","metaTitle":"STM32L071RBT6 MCU, ARM Cortex-M0+, 32MHz, 128KB Flash","metaDescription":"STM32L071RBT6 32-bit MCU, ARM Cortex-M0+ at 32MHz, 128KB Flash, 20KB RAM, 6KB EEPROM, 51 I/O, 16x12b ADC, 1.65-3.6V, -40 to 85°C, 64-LQFP.","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, I²S, POR, PWM, WDT","Connectivity":"I²C, IrDA, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"51","Core Processor":"ARM® Cortex®-M0+","Package / Case":"64-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b","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 ~ 85°C (TA)","Supplier Device Package":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.1300","priceTiers":[{"qty":1,"price":"$5.13000","currency":"USD"},{"qty":10,"price":"$4.60600","currency":"USD"},{"qty":25,"price":"$4.35440","currency":"USD"},{"qty":80,"price":"$3.77375","currency":"USD"},{"qty":230,"price":"$3.58022","currency":"USD"},{"qty":440,"price":"$3.21252","currency":"USD"},{"qty":960,"price":"$2.70936","currency":"USD"},{"qty":2880,"price":"$2.57390","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/22d621a76748b868dc4a8fc30085ea48.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L071RBT6/alternatives.json"},"ai":{"faq":[{"question":"What are the alternatives to STM32L071RBT6?","answer":"A functional alternative within the STM32 portfolio is the STM32L151CBU6A, which uses a Cortex-M3 core (also 32-bit at 32 MHz) and adds a 12-bit DAC and USB connectivity, but comes in a 48-pin package with fewer I/O (37) and no embedded EEPROM.
