This removes the sourcing risk for new designs and production ramps. For dual-sourcing resilience, the STM32L4 family includes pin-compatible density variants (e.g., 512 KB Flash parts) that share the same 100-UFBGA footprint, though firmware migration and peripheral differences must be validated. ## Peripheral set and connectivity — what hooks up where Beyond the core, this MCU integrates a brown-out detect/reset, DMA controller, LCD driver, PWM timers, and a watchdog timer. Connectivity spans CANbus, I²C, IrDA, LINbus, MMC/SD, QSPI, SAI, SPI, SWPMI, and multiple UART/USART channels — enough to bridge sensors, displays, wireless modules, and fieldbus interfaces in a single chip.","metaTitle":"STM32L433VCI6 STM32L4 ARM Cortex-M4 MCU, 80 MHz","metaDescription":"STM32L433VCI6 is an STM32L4 32-bit ARM Cortex-M4 MCU with 80 MHz core, 256 KB Flash, 64 KB SRAM, 83 I/O, 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":"STM32L433","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":"$3.9466","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6e323d1827cad59f98cd5297642b464c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L433VCI6/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM32L433VCI6?","answer":"Within the STM32L4 series, the STM32L433VCT6 shares the same core and peripheral set but differs in package (100-LQFP vs 100-UFBGA) — not pin-compatible due to different footprint.
