The peripheral set includes CANbus, QSPI, SAI audio, and USB, plus an LCD driver for segment displays. Brown-out detect and reset are built in, reducing external supervisor IC cost.","metaTitle":"STM32L433CCT3 STM32L4 MCU, 80MHz Cortex-M4, 256KB Flash","metaDescription":"STMicroelectronics STM32L433CCT3 ARM Cortex-M4 MCU at 80MHz with 256KB Flash, 64KB SRAM, 10x12b ADC, -40°C to 125°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-LQFP","Product Status":"Active","Data Converters":"A/D 10x12b; 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 ~ 125°C (TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.9600","priceTiers":[{"qty":1,"price":"$6.96000","currency":"USD"},{"qty":10,"price":"$6.28600","currency":"USD"},{"qty":25,"price":"$5.99360","currency":"USD"},{"qty":80,"price":"$5.20413","currency":"USD"},{"qty":230,"price":"$4.97022","currency":"USD"},{"qty":440,"price":"$4.53166","currency":"USD"},{"qty":1500,"price":"$3.94693","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6e323d1827cad59f98cd5297642b464c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L433CCT3/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32L433CCT3 and the STM32L151CBU6A?","answer":"The STM32L433CCT3 runs an ARM Cortex-M4 at 80 MHz with FPU, compared to the STM32L151CBU6A's Cortex-M3 at 32 MHz.
