GD32H757xx Datasheet



Outputs to timers for capture.



Outputs to EXTI and NVIC.

The general purpose comparators, CMP0 and CMP1, can work either standalone (all terminal

are available on I/Os) or together with the timers. It could be used to wake up the MCU from

low-power mode by an analog signal, provide a trigger source when an analog signal is in a

certain condition, achieves some current control by working together with a PWM output of a

timer and the DAC. It blanking function can be used for false overcurrent detection in motor

control applications.

High-Performance Digital Filter (HPDF)



8 multiplex digital serial input channels.

configurable SPI and Manchester interfaces.



8 internal digital parallel input channels.

input with up to 16-bit resolution.

internal source: ADC data or memory (CPU/DMA write) data stream.



Configurable Sinc filter and integrator.

the order and oversampling rate (decimation rate) of Sinc filter can be configured.

sampling rate of configurable integrator.



Threshold monitor function.

independent Sinc filter, configurable order and oversampling rate (decimation rate).

configurable data input source: serial channel input data or HPDF output data.



Malfunction monitor function.

A counter with 8 bits is used to monitor the continuous 0 or 1 in the serial channel

input data stream.



Extreme monitor function.

store minimum and maximum values of output data values of HPDF.



Up to 24-bit output data resolution.



Clock signal can be provided to external sigma delta modulator.

provide configurable clock signal by the CKOUT pin.



HPDF output data is in signed format.

A high performance digital filter module (HPDF) for external sigma delta (Σ-Δ) modulator is

integrated in GD32H757xx. HPDF supports SPI interface and Manchester-coded single-wire

interface. The external sigma delta modulator can be connected with MCU by the serial

interface, and the serial data stream output by sigma delta modulator can be filtered. In

addition, HPDF also supports the parallel data stream input,

which can be selected from

internal ADC peripherals or from MCU memory.

Real-time decryption (RTDEC)



Software configurable encrypted areas up to 4.
