That 84 MHz core speed means the part can run DSP filters and floating-point control loops without a separate accelerator — useful for motor control, audio processing, or sensor fusion where the math stays on-chip. The 384 KB Flash and 96 KB RAM give enough room for a modest RTOS, a USB stack, and a few hundred kilobytes of application code without squeezing into a smaller density tier. ## Peripheral set and I/O budget Fifty GPIOs in the 64-LQFP package give reasonable headroom for a mixed-signal board with a parallel LCD, keypad matrix, and a few external peripherals. The connectivity block includes USB OTG (host or device), two SPI, three USART, two I²C, SDIO, and I²S — enough for a sensor hub or a fieldbus gateway. On-chip data converters are a single 12-bit ADC with 16 channels, so if you need a DAC or a second ADC, you budget external parts. ## Industrial temperature range — where it fits It belongs in outdoor telecom enclosures, factory-floor controllers, engine-bay-adjacent electronics, and HVAC systems. ST lists the STM32F401RDT6 as Active.","metaTitle":"ST STM32F401RDT6 ARM Cortex-M4 MCU, 84 MHz, 384 KB Flash","metaDescription":"STM32F401RDT6 32-bit ARM Cortex-M4 MCU from STMicroelectronics. 84 MHz core, 384 KB Flash, 96 KB RAM, 50 I/O, USB OTG, industrial temp -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":"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":"50","Core Processor":"ARM® Cortex®-M4","Package / Case":"64-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":"64-LQFP (10x10)","Voltage - Supply (Vcc/Vdd)":"1.7V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.2400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c1395acb0fdce6474233414430f990ad.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F401RDT6/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between STM32F401RDT6 and STM32F401RCT6?","answer":"The key difference is Flash density: the STM32F401RDT6 carries 384 KB Flash, while the STM32F401RCT6 is the 256 KB variant.
