Connectivity includes CANbus, EBI/EMI, I2C, IrDA, LINbus, MMC/SD, SAI, SPI, UART/USART, and USB OTG — enough to serve as the central controller in an IoT gateway, a motor-drive interface board, or a portable medical monitor. The 38 I/O lines in the 48-UFQFN package give reasonable breakout for mixed-signal designs.","metaTitle":"STM32L4P5CEU6 ARM Cortex-M4 MCU, 120 MHz, 512 KB Flash","metaDescription":"STMicroelectronics STM32L4P5CEU6 32-bit MCU with 120 MHz Cortex-M4 core, 512 KB Flash, 320 KB SRAM, rich connectivity including CAN and USB OTG.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Grade":"-","Speed":"120MHz","Series":"STM32L4","Package":"Tray","RAM Size":"320K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, LCD, POR, PWM, WDT","Connectivity":"CANbus, EBI/EMI, I2C, IrDA, LINbus, MMC/SD, SAI, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"38","Qualification":"-","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":"STM32L4P5","Program Memory Size":"512KB (512K 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":"$10.7600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/864b0095aefddec5383cd033b8022454.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM32L4P5CEU6 in this component family?","answer":"Within the STM32L4 series, pin-compatible density variants exist (e.g., STM32L4P5xx with different Flash/SRAM sizes). The base product number STM32L4P5 shares the same footprint, so a swap requires checking the memory map and peripheral set, not the board layout."},{"question":"What is STM32L4P5CEU6's listed speed?","answer":"The core runs at 120 MHz, which is the maximum clock for this Cortex-M4 device. At that speed, the Flash needs at least one wait state inserted; the STM32L4's prefetch buffer helps maintain single-cycle execution for sequential code."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STM32L4P5CEU6","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STM32L4P5CEU6 when reusing this data.
