 Hello and welcome to this presentation of the STM32U5 Analog Comparators. It covers the main features of these ultra-low power comparators. Two comparators inside the STM32U5 microcontrollers provide a binary output, which indicates if the analogue voltage on the positive input is larger than the voltage on the negative input. They allow the microcontrollers to react when the analogue signal crosses a predefined threshold. The comparator continuously monitors voltage in contrast to an analogue to digital converter, which operates in sampled mode. Each comparator has three speeds mode. Input can be selectable from GPIOs, internal reference voltage as well as DAC output voltage. Output can be routed to GPIO and also timer or interrupt inputs through the peripheral interconnect matrix. Hysteresis voltage is programmable and by combining the two comparators, it's possible to implement a window mode that monitors if the analogue voltage is within the voltage range defined by lower and upper thresholds. There's also an integrated mechanism to calibrate the offset. Outputs can often be used as a wake-up source. Compared to the STM32L5, the comparator of the STM32U5 features a lower propagation delay. This table shows the internal and external connections of the comparator inputs and outputs. Each comparator has two analogue inputs and one digital output. The positive input is connected to a GPIO pad while the negative input can be connected either to a GPIO pad or internally to DAC outputs or Vref int with four divide ratios. The output of the comparator can be inverted. The state of the comparator can be connected to GPIOs, an interrupt request, EXTI module to generate a wake-up request or an event to the CPU, timer inputs, triggers for communication peripherals, triggers to GPDMA or LPDMA. These two last possibilities are new with respect to the STM32L5. It's possible to have the comparator output simultaneously redirected internally and externally. Motor control loop is simplified by enabling a corporation between the following units comparators, timers, DACs and Vref int. Refer to the following presentations for peripherals connected to the comparators IMX, interconnect matrix, GPIO, general purpose inputs and outputs.
