For control loops, FFTs, or audio processing, the M4's DSP extensions and floating-point unit cut cycle counts significantly. ## Package and supply — footprint and rail planning The 1.71 V minimum supply means a single Li-ion cell or two alkaline cells can power the MCU directly — no boost converter needed. The 38 GPIOs are enough for a keypad, small TFT, or sensor array without port expansion.","metaTitle":"STMicroelectronics STM32L443CCU6 MCU, ARM Cortex-M4 80 MHz","metaDescription":"STMicroelectronics STM32L443CCU6 32-bit ARM Cortex-M4 MCU, 80 MHz speed, 256 KB Flash, 64 KB SRAM, 1.71-3.6 V supply, -40 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-UFQFN Exposed Pad","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-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.1700","priceTiers":[{"qty":1,"price":"$6.17000","currency":"USD"},{"qty":10,"price":"$5.57200","currency":"USD"},{"qty":25,"price":"$5.31280","currency":"USD"},{"qty":80,"price":"$4.61313","currency":"USD"},{"qty":230,"price":"$4.40583","currency":"USD"},{"qty":440,"price":"$4.01707","currency":"USD"},{"qty":1560,"price":"$3.49874","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/95850be2029da0766935bf1246526e77.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L443CCU6/alternatives.json"},"ai":{"faq":[{"question":"What is the listed speed of the STM32L443CCU6?","answer":"The STM32L443CCU6 is rated for 80 MHz operation with its ARM Cortex-M4 core."},{"question":"What series does the STM32L443CCU6 belong to?","answer":"It belongs to the STM32L4 series, which is STMicroelectronics' ultra-low-power ARM Cortex-M4 family."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L443CCU6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L443CCU6 when reusing this data.
