GD32H757xx Datasheet



Compliant with the ISO 11898-1:2015 standard.



Supports CAN FD frame with up to 64 data bytes, baudrate up to 8 Mbit/s.



Supports CAN classical frame with up to 8 data bytes, baudrate up to 1 Mbit/s.



Supports time stamp based on 16-bit free running counter.



Supports transmitter delay compensation for CAN FD frames at faster data rates.



Maskable interrupts.



Supports four communication mode: normal mode, Inactive mode, Loopback and silent

mode, and Monitor mode.



Supports two power saving modes: CAN_Deepsleep mode, and CAN_sleep mode.



Support two wakeup methods for waking up from Pretended Networking mode: wakeup

matching event, and wakup timeout event.



Global network time, synchronized by a specific message.

CAN bus (Controller Area Network) is a bus standard designed to allow microcontrollers and

devices to communicate with each other without a host computer. The CAN interface supports

the CAN 2.0A/B protocol, ISO 11898-1:2015 and BOSCH CAN FD specification.

The CAN module is a CAN Protocol controller with a very flexible mailbox system for

transmitting and receiving CAN frames. The mailbox system consists of a set of mailboxes

that store configuration and control data, timestamp, message ID, and data. The space of up

to 32 mailboxes can also be configured as Rx FIFO with ID filtering against up to 104 extended

IDs or 208 standard IDs or 416 partial 8-bit IDs, and configure receive FIFO/mailbox private

filter register for up to 32 ID filter table elements.

Ethernet (ENET)



IEEE 802.3 compliant media access controller (MAC) for Ethernet LAN.

 10/100 Mbit/s rates

with dedicated DMA controller and SRAM.



Support hardware precision time protocol (PTP) with conformity to IEEE 1588.

The Ethernet media access controller (MAC) conforms to IEEE 802.3 specifications and fully

supports IEEE 1588 standards. The embedded MAC provides the interface to the required

external network physical interface (PHY) for LAN bus connection via a reduced media

independent interface (RMII). The number of RMII signals provided up to 7 with 50 MHz output.

The function of 32-bit CRC checking is also available.

3.41.

Comparator (CMP)



Rail-to-rail comparators.



Configurable hysteresis.



Configurable speed and consumption.



Each comparator has configurable analog input source.



Outputs with blanking source.



Outputs to I/O.
