The Cortex-M4 core includes single-cycle DSP and floating-point instructions, so a motor-control or audio-processing loop that would stall an M3 core runs in fewer cycles here. The 50 available I/Os and the 16-channel 12-bit ADC give it enough analog front-end and digital interface density for a mid-complexity industrial controller or a sensor-fusion node. ## Connectivity and peripherals — what is on the bus Connectivity includes I2C, SPI, UART/USART, IrDA, LINbus, SDIO, and USB OTG — enough for a multi-sensor hub talking to a host over USB or a CAN gateway via an external transceiver. The peripheral set includes brown-out detect, POR, PWM timers, a watchdog, DMA, and I2S for audio codec interface. ## Lifecycle and sourcing — EOL reality for this STM32F4 line The STM32F401VBH3 carries an EOL-hot lifecycle stage. For a production BOM, this means the procurement team should lock in a final buy quantity or qualify a pin-compatible replacement within the STM32F4 family.","metaTitle":"STMicroelectronics STM32F401VBH3 ARM Cortex-M4 MCU, 84MHz","metaDescription":"STM32F401VBH3 32-bit MCU with ARM Cortex-M4 core at 84 MHz, 128 KB Flash, 64K x 8 RAM, 100-UFBGA, -40°C to 125°C.
