The 96 KB SRAM splits between a main 64 KB block and a 32 KB CCM (core-coupled memory) accessible only by the CPU — no DMA. That CCM region is ideal for interrupt stacks or time-critical loops, but watch the linker script: placing a DMA buffer there will silently fail. ## USB OTG, 81 I/O, and the peripheral mix Connectivity includes USB OTG (full-speed), three SPI, three I²C, six UART/USART, SDIO, and I²S — enough for a sensor hub or a small HMI panel. Brown-out detect, POR, and a windowed watchdog are on-chip, so external supervisor ICs are optional for most industrial designs. For procurement, this means the part is factory-supported and can be specified into production without near-term obsolescence risk.","metaTitle":"STM32F401VET6 STM32F4 ARM Cortex-M4 MCU, 84 MHz","metaDescription":"STMicroelectronics STM32F401VET6 32-bit ARM Cortex-M4 MCU at 84 MHz with 512 KB Flash, 96 KB SRAM, USB OTG, 81 I/O, in 100-LQFP.","metaKeywords":null},"attributes":{"series":"STM32F4","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"84MHz","Series":"STM32F4","Package":"Tray","RAM Size":"96K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, 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":"STM32F401","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":"$8.9600","priceTiers":[{"qty":1,"price":"$8.96000","currency":"USD"},{"qty":10,"price":"$8.09700","currency":"USD"},{"qty":25,"price":"$7.72000","currency":"USD"},{"qty":90,"price":"$6.70322","currency":"USD"},{"qty":270,"price":"$6.40200","currency":"USD"},{"qty":450,"price":"$5.83713","currency":"USD"},{"qty":990,"price":"$5.08395","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c1395acb0fdce6474233414430f990ad.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F401VET6/alternatives.json"},"ai":{"faq":[{"question":"Does STM32F401VET6 have USB OTG?","answer":"Yes, the connectivity list includes USB OTG.
