STM32H745ZIT6U Description
STM32H745ZIT6U is a 32-Bit Microcontroller Nucleo-144 with Internal SMPS Function Development Board. The STM32H745ZIT6U has 12 general-purpose 16-bit timers, three ADCs, two DACs, two ultra-low-power comparators, a low-power RTC, a high-resolution timer, two PWM timers for motor control, five low-power timers, and a genuine random number generator (RNG). For external sigma-delta modulators, the STM32H745ZIT6U supports four digital filters (DFSDM). Standard and cutting-edge communication interfaces are also included.
