The connectivity block includes CANbus, USB, multiple SPI and I²C interfaces, plus QSPI for a fast external Flash or RAM. Brown-out detect and a watchdog timer are built in, so external supervisor ICs are optional. ## Industrial temperature range in a fine-pitch BGA Plan for a 4-layer or higher PCB to route the BGA fan-out. ## Active lifecycle — no LTB concern It is a current-production part with no announced end-of-life. New designs can commit to this order code without near-term obsolescence risk.","metaTitle":"STM32L443VCI6 ARM Cortex-M4 MCU, 80 MHz, 256 KB Flash","metaDescription":"STMicroelectronics STM32L443VCI6: 32-bit ARM Cortex-M4 at 80 MHz, 256 KB Flash, 64 KB SRAM, 83 I/O, industrial temp -40°C to 85°C, 100-UFBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"83","Core Processor":"ARM® Cortex®-M4","Package / Case":"100-UFBGA","Product Status":"Active","Data Converters":"A/D 16x12b; 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":"100-UFBGA (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.5200","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/95850be2029da0766935bf1246526e77.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the maximum clock speed of STM32L443VCI6?","answer":"The STM32L443VCI6 runs at 80 MHz from its internal oscillator or an external clock."},{"question":"How many I/O pins does STM32L443VCI6 have?","answer":"It provides 83 I/O lines in the 100-UFBGA package."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L443VCI6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L443VCI6 when reusing this data.
