There's also an LCD segment driver controller on die — handy for a local display on a pump controller or a thermostat. ## Industrial temperature and package reality The 48-UFQFN with exposed pad (7x7 mm) needs a solid via-stitch under the paddle to pull heat into the ground plane — skip that and the junction creeps above the 85°C limit at full I/O load. That means no last-time-buy scramble and no forced redesign for the next production run.","metaTitle":"STM32L433CCU6TR STM32L4 ARM Cortex-M4 MCU, 80 MHz","metaDescription":"STMicroelectronics STM32L433CCU6TR 32-bit ARM Cortex-M4 MCU, 80 MHz, 256 KB Flash, 64 KB SRAM, 48-UFQFN, -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":"38","Core Processor":"ARM® Cortex®-M4","Package / Case":"48-UFQFN Exposed Pad","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~85°C(TA)","Supplier Device Package":"48-UFQFPN (7x7)","Voltage - Supply (Vcc/Vdd)":"1.71V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.0618","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/37b3da3088ec0d3cef475dc2db554cdd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32L433CCU6TR/alternatives.json"},"ai":{"faq":[{"question":"Is STM32L433CCU6TR active or obsolete?","answer":"The lifecycle status is Active."},{"question":"What is the difference between STM32L433CCU6TR and STM32L433CCU6?","answer":"The two are electrically identical.
