The 64 KB SRAM supports a modest RTOS heap and double-buffered ADC buffers. Connectivity includes CAN, USB, and multiple UART/SPI/I²C. ## Temperature grade and package — where it lives on the board The exposed pad should be stitched to the ground plane with thermal vias if the MCU drives multiple peripherals at 80 MHz.","metaTitle":"STM32L433VCT6TR STMicroelectronics MCU, 32-bit ARM Cortex-M4","metaDescription":"STM32L433VCT6TR 32-bit ARM Cortex-M4 MCU, 80 MHz, 256KB Flash, 64KB SRAM, 83 I/O, -40°C to 85°C, 100-LQFP.","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":"Tape & Reel (TR); Cut Tape (CT)","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-LQFP","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-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.9300","priceTiers":[{"qty":1,"price":"$8.93000","currency":"USD"},{"qty":10,"price":"$8.06900","currency":"USD"},{"qty":25,"price":"$7.69360","currency":"USD"},{"qty":100,"price":"$6.68030","currency":"USD"},{"qty":250,"price":"$6.38008","currency":"USD"},{"qty":500,"price":"$5.81712","currency":"USD"},{"qty":1000,"price":"$5.11770","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6e323d1827cad59f98cd5297642b464c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L433VCT6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum clock speed of STM32L433VCT6TR?","answer":"The STM32L433VCT6TR runs at 80 MHz.
