Description

MCP2551 high-speed CAN communication protocol controller bus interface module

CJMCU-2551 is a fault-tolerant high-speed CAN device that can be used as a CAN protocol controller and physical bus interface. The MCP2551 can provide differential transceiver capabilities for the CAN protocol controller. It is fully compliant with the ISO-11898 standard, including the ability to meet the 24V voltage requirement.

Typically, each node on the CAN system must have a device to convert the digital signal generated by the CAN controller into a signal suitable for bus transmission. It also adds a buffer between the CAN controller and the high-voltage spikes on the CAN bus. These high-voltage spikes may be generated by external devices.

Support 1MB/S operating rate.

·Meet the physical layer requirements of the ISO-11898 standard.

·Suitable for 12V and 24V systems. The slope is controlled externally to reduce RFI.

·Automatically detect the grounding error of the TXD input terminal.

·Power-on reset and voltage event under-voltage protection.

·Unpowered nodes or undervoltage will not affect the CAN bus.

· Low current standby operation.

·Can connect up to 112 nodes.
