A typical LoRa sensor node firmware — radio stack, sensor driver, and application loop — fits in about 20 KB of Flash and uses 4 KB of SRAM for buffers, leaving headroom for OTA staging or additional protocol layers. The 1 KB EEPROM (1K x 8) stores calibration coefficients and network credentials without wearing the Flash. If your firmware exceeds 30 KB or the SRAM budget for DMA and communication stacks pushes past 6 KB, step up to the STM32L051 or STM32L073 density options. No exposed pad — thermal dissipation relies on the leadframe and board copper. ROHS3 compliance is confirmed, covering the current EU RoHS exemption list. For volume production commitments, the active status removes the obsolescence risk that drives spot-market premiums.","metaTitle":"STM32L031K6T6TR ARM Cortex-M0+ MCU, 32 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32L031K6T6TR 32-bit ARM Cortex-M0+ MCU, 32 MHz core, 32 KB Flash, 8 KB SRAM, 1 KB EEPROM, 10-ch 12-bit ADC, -40 to 85°C, 32-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":"Tape & Reel (TR) Cut Tape (CT)","RAM Size":"8K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"1K x 8","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"25","Core Processor":"ARM® Cortex®-M0+","Package / Case":"32-LQFP","Product Status":"Active","Data Converters":"A/D 10x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L031","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"32-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.3900","priceTiers":[{"qty":1,"price":"$3.39000","currency":"USD"},{"qty":10,"price":"$3.04600","currency":"USD"},{"qty":25,"price":"$2.88000","currency":"USD"},{"qty":100,"price":"$2.49590","currency":"USD"},{"qty":250,"price":"$2.36796","currency":"USD"},{"qty":500,"price":"$2.12476","currency":"USD"},{"qty":1000,"price":"$1.79196","currency":"USD"},{"qty":2400,"price":"$1.70236","currency":"USD"},{"qty":4800,"price":"$1.63836","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/9da9efc4233dfdd482528b8b281fc32a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L031K6T6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32L031K6T6TR and STM32L031K6T6?","answer":"The STM32L031K6T6TR is the Tape & Reel (TR) packaged variant of the STM32L031K6T6.
