The exposed pad is not present on this variant — all thermal dissipation goes through the leads, so keep the copper pour under the package solid and stitch vias to the ground plane if the application draws more than 200 mA continuous. For dual-sourcing resilience, the STM32F411 family includes pin-compatible density variants (e.g., 256 KB Flash / 64 KB SRAM) that share the same 100-LQFP footprint — a drop-in swap if the firmware budget shrinks, though the 512 KB Flash version is the one to qualify first.","metaTitle":"ST STM32F411VET6U ARM Cortex-M4 MCU, 100 MHz, 512 KB Flash","metaDescription":"STMicroelectronics STM32F411VET6U 32-bit ARM Cortex-M4 MCU at 100 MHz with 512 KB Flash, 128 KB SRAM, 81 I/O, USB OTG.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"100MHz","Series":"STM32F4","Package":"Tray","RAM Size":"128K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, MMC/SD/SDIO, SPI, UART/USART, USB OTG","Mounting Type":"Surface Mount","Number of I/O":"81","Core Processor":"ARM® Cortex®-M4","Package / Case":"100-LQFP","Product Status":"Active","Data Converters":"A/D 16x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM32F411","Program Memory Size":"512KB (512K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"100-LQFP (14x14)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$12.0800","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/69787e31837c3201468cce0037d389f1.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F411VET6U/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F411 and STM32F405?","answer":"The STM32F405 runs at up to 168 MHz and includes up to 1 MB Flash and 192 KB SRAM, plus a full-speed USB OTG with PHY and two CAN interfaces.
