MCP2551 High speed CAN communication protocol controller bus interface module

The CJMCU-2551 is a fault-tolerant high-speed CAN device that functions as a CAN protocol controller and physical bus interface. The MCP2551 provides differential transceiver capability for the CAN protocol controller, which is fully ISO-11898 compliant, including 24V voltage requirements.

Typically, each node on the CAN system must have a device that converts 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 high-voltage spikes on the CAN bus that may be generated by external devices.

Supports 1MB/S running rate.
· Meet the physical layer requirements of ISO-11898 standard.
· Suitable for 12V and 24V systems. Slope external control to reduce RFI.
· Automatically detects grounding errors at the TXD input.
· Power-on reset and undervoltage protection during voltage events.
· The CAN bus is not affected if the node is not powered on or underpowered.
· Low current standby operation.
· Up to 112 nodes can be connected.
