MCP2551 CAN Controller Module

Overview

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

Typically, each node on the 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 a buffer between the CAN controller and the high-voltage spike on the CAN bus. These high-voltage spikes may be generated by external devices.

Supports 1MB/S operating rate

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

• Suitable for 12 V and 24 V systems. Slope external control to reduce RFI.

• Automatic detection of grounding errors at the TXD input.

• Power-on reset and voltage event Undervoltage protection.

• The power-up node or Undervoltage does not affect the CAN bus.

• Low current standby operation.

• Up to 112 connectable nodes.
