The ROHS3 compliance covers current environmental regulations. If you are planning a multi-year production run, this is a safe choice — no need to stockpile a last-time-buy.","metaTitle":"STM32L443CCT6 STM32L4 MCU, 80MHz Cortex-M4, 256KB Flash","metaDescription":"STM32L443CCT6 32-bit ARM Cortex-M4 MCU at 80 MHz with 256 KB Flash, 64 KB SRAM, 1.71V–3.6V supply, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":"STM32L4","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"80MHz","Series":"STM32L4","Package":"Tray","RAM Size":"64K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, LCD, PWM, WDT","Connectivity":"CANbus, I²C, IrDA, LINbus, MMC/SD, QSPI, SAI, SPI, SWPMI, UART/USART, USB","Mounting Type":"Surface Mount","Number of I/O":"38","Core Processor":"ARM® Cortex®-M4","Package / Case":"48-LQFP","Product Status":"Active","Data Converters":"A/D 10x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L443","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.3400","priceTiers":[{"qty":1,"price":"$6.34000","currency":"USD"},{"qty":10,"price":"$5.73100","currency":"USD"},{"qty":25,"price":"$5.46480","currency":"USD"},{"qty":80,"price":"$4.74488","currency":"USD"},{"qty":230,"price":"$4.53170","currency":"USD"},{"qty":440,"price":"$4.13182","currency":"USD"},{"qty":1500,"price":"$3.59869","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/95850be2029da0766935bf1246526e77.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L443CCT6/alternatives.json"},"ai":{"faq":[{"question":"How does STM32L443CCT6 compare to the older STM32L151CBU6A?","answer":"The STM32L151CBU6A runs a Cortex-M3 core at 32 MHz, while the STM32L443CCT6 uses a Cortex-M4 at 80 MHz — roughly 2.5x the clock speed plus DSP and FPU instructions. The STM32L4 also adds USB, QSPI, and SAI connectivity that the lacks, and the supply range extends down to 1.71 V versus 1.8 V. If you are migrating from an design, the L4 gives you more headroom for signal processing and a wider voltage operating window."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L443CCT6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L443CCT6 when reusing this data.
