That core includes a single-cycle multiply and a hardware FPU — so it handles PID loops, FFTs, or sensor fusion without a separate DSP. ## I/O and connectivity for a control board Fifty GPIOs in a 64-LQFP package leave room for a parallel LCD interface, a keypad matrix, and a handful of sensors. The 16-channel 12-bit ADC covers analog inputs like thermistors or current shunts without an external converter. ST lists this part as Active. It is not qualified for under-hood automotive (125°C) or avionics extended-temperature ranges — if your design needs that, look at the STM32F4 automotive-grade variants or the STM32G4 series with AEC-Q100 certification. ## Supply range and power management The built-in brown-out detect and POR eliminate the need for an external supervisor in many designs.","metaTitle":"STM32F401RET6TR STM32F4 ARM Cortex-M4 MCU, 84 MHz","metaDescription":"STM32F401RET6TR 32-bit ARM Cortex-M4 MCU, 84 MHz speed, 512 KB Flash, 96 KB RAM, 50 I/O, 64-LQFP, -40°C 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":"Tape & Reel (TR); Cut Tape (CT)","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":"512KB (512K 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":"$9.1400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c1395acb0fdce6474233414430f990ad.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM32F401RET6TR/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to STM32F401RET6TR?","answer":"Within the STM32F401 family, the STM32F401RCT6 (256 KB Flash, 64 KB RAM) and STM32F401RDT6 (384 KB Flash, 96 KB RAM) are pin-compatible in the same 64-LQFP package.
