This MCU runs at 32 MHz and includes I²C, SPI, and UART connectivity. ## Memory budget and the firmware-fit decision It handles a modest FreeRTOS heap, a BLE stack stub, or a deterministic control loop — but you will bump into the Flash ceiling if the application needs a full GUI library or over-the-air update with dual-image banking. The 1 KB EEPROM (emulated or native) is a genuine advantage: it stores calibration constants and device serial numbers without wearing the Flash, and it survives 100k write cycles typical of the STM32L0 embedded EEPROM. For a design that ships with field-reprogrammable parameters, this saves an external 24LCxx part and its PCB footprint. If your build needs -40°C to 125°C or AEC-Q100, this is not the part; you step up to the STM32L0 automotive-grade variants. ## Lifecycle and sourcing posture That makes it a safe BOM line for production builds without last-time-buy risk. If you are dual-sourcing, the entire STM32L041 base product number shares the same pinout across Flash-density options, so a swap to a higher-density variant is a firmware recompile away without a board spin.","metaTitle":"STM32L041C6T6TR ARM Cortex-M0+ MCU, 32 MHz, 32 KB Flash","metaDescription":"STMicroelectronics STM32L041C6T6TR 32-bit MCU, ARM Cortex-M0+ core at 32 MHz, 32 KB Flash, 8 KB RAM, 1 KB EEPROM, 48-LQFP, -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":"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":"38","Core Processor":"ARM® Cortex®-M0+","Package / Case":"48-LQFP","Product Status":"Active","Data Converters":"A/D 10x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L041","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.8V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.8070","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/753c77324476fdd7794c6f26274fa242.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy STM32L041C6T6TR and get current pricing?","answer":"This part is available to order through independent distribution.
