For the BOM planner, that means no forced requalification or spot-market scramble in the near term.","metaTitle":"STM32L433RCI6TR STM32L4 ARM Cortex-M4 80 MHz MCU","metaDescription":"STMicroelectronics STM32L433RCI6TR 32-bit ARM Cortex-M4 MCU at 80 MHz with 256 KB Flash, 64 KB SRAM, 52 I/O, CANbus, USB, 12-bit ADC/DAC, -40 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":"80MHz","Series":"STM32L4","Package":"Tape & Reel (TR)","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":"52","Core Processor":"ARM® Cortex®-M4","Package / Case":"64-UFBGA","Product Status":"Active","Data Converters":"A/D 16x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32L433","Program Memory Size":"256KB (256K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"64-UFBGA (5x5)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.3868","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e323d1827cad59f98cd5297642b464c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L433RCI6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32L433RCI6TR and STM32L433RCI6?","answer":"The STM32L433RCI6TR is the Tape & Reel (TR) shipping option of the same die and package as the STM32L433RCI6. Electrically and mechanically identical — the suffix only changes the delivery format for pick-and-place lines. The TR variant comes on a reel; the non-TR variant typically ships in tray or tube."},{"question":"Is STM32L433RCI6TR RoHS compliant?","answer":"The STM32L4 series from STMicroelectronics is manufactured RoHS-compliant by default. No separate RoHS certificate is needed for standard production lots; the part carries the usual green marking."},{"question":"What is STM32L433RCI6TR's listed speed?","answer":"The core runs at 80 MHz. That is the maximum CPU clock; the flash prefetch and ART accelerator keep it fed without wait-state penalties at that speed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L433RCI6TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L433RCI6TR when reusing this data.
