Bus Interface Module

Product Information:

CJMCU-2551 is a fault-tolerant high-speed CAN device, which can be used as CAN protocol controller and physical bus interface. MCP2551 can provide differential transceiver capability for CAN protocol controller, it fully complies with ISO-11898 standard, including 24V voltage requirement.

Typically, each node on a CAN system must have a device that converts the digital signals generated by the CAN controller into signals suitable for bus transmission. It also adds buffers between the CAN controller and high voltage spikes on the CAN bus that may be generated by external devices.

Support 1MB/S operating rate.

·Meet the ISO-11898 standard physical layer requirements.

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

·Automatic detection of ground errors at the TXD input.

· Power-on reset and voltage event undervoltage protection.

Unpowered nodes or undervoltage will not affect the CAN bus.

· Low current standby operation.

· Up to 112 nodes can be connected.
