The peripheral list covers Brown-out Detect, DMA, I²S, POR, PWM, and WDT — the usual STM32F4 complement for motor control and audio applications. Connectivity extends to EBI/EMI for parallel memory or displays, plus IrDA and LINbus for legacy industrial buses.
The STM32F427IIT6 is rated for a 180 MHz core clock. That speed, combined with the ARM Cortex-M4 DSP extensions and FPU, handles real-time control loops and signal-processing tasks without an external DSP.
