The 96 KB SRAM is enough for a FreeRTOS heap with several moderate-sized buffers, a USB stack, and a TCP/IP offload. For most sensor-fusion, fieldbus-gateway, or UI-controller tasks, this memory balance works without external RAM. ## 81 I/O in a 100-LQFP — routing and footprint The 100-LQFP package (14x14 mm body) brings out 81 general-purpose I/O. That is enough for a parallel LCD interface, an external memory bus, and several serial peripherals simultaneously. The fine-pitch (0.5 mm) QFP is hand-solderable with a decent iron and a flux pen, but for production runs a reflow profile per J-STD-020 is the standard. ## Connectivity and peripherals for a system-on-chip approach The peripheral set includes USB OTG (host/device), SDIO for SD cards, three SPI, three I²C, and up to six UART/USART with IrDA and LIN support. The internal oscillator is accurate enough for UART baud-rate generation but not for USB — an external crystal is recommended for USB operation. ## Industrial temperature range and lifecycle ROHS3 compliant. No AEC-Q100 qualification — not for automotive under-hood or chassis domains. ## Sourcing posture for the STM32F401VDT6 This part is in the active allocation window for the STM32F4 family. Lead times have stabilized from the 2021-2023 shortage peaks, but the 100-LQFP variant can still see extended cycles during high-demand quarters. We source through franchised distribution and verified independent channels, with traceability back to the manufacturer date code.","metaTitle":"STM32F401VDT6 ARM Cortex-M4 MCU, 84MHz, 384KB Flash","metaDescription":"STMicroelectronics STM32F401VDT6 32-bit MCU with ARM Cortex-M4 core at 84MHz, 384KB Flash, 96KB SRAM, 81 I/O, USB OTG, industrial temp -40°C to 85°C.","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":"384KB (384K 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":"$8.2200","priceTiers":[{"qty":1,"price":"$8.22000","currency":"USD"},{"qty":10,"price":"$7.42700","currency":"USD"},{"qty":25,"price":"$7.08120","currency":"USD"},{"qty":90,"price":"$6.14867","currency":"USD"},{"qty":270,"price":"$5.87230","currency":"USD"},{"qty":450,"price":"$5.35416","currency":"USD"},{"qty":990,"price":"$4.66330","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/c1395acb0fdce6474233414430f990ad.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F401VDT6/alternatives.json"},"ai":{"faq":[{"question":"What is the maximum clock speed of STM32F401VDT6?","answer":"The core runs at 84 MHz.
