Description of product

MCP2551 High SPeed Interface Controller Module - (High Quality)


The CJMCU-2551 MCP2551 CAN Protocol Controller High-speed Interface Module is a high speed CAN, with fault-tolerant capabilities. It acts as an interfacing device between CAN protocol and the physical bus. The device, MCP2551 provides differential transmit and receive capabilities and is compliant with the ISO-11898, including the 24V requirements. Data transfer rate of up to 1Mb/s is achievable with this module.

The module also provides a buffer between the CAN controller and the high-voltage spikes that can be generated on the CAN bus by outside sources like EMI, ESD, electrical transients, etc.


  • Supports 1 Mb/s operation
  • Implements ISO-11898 standard physical layer requirements
  • Suitable for 12V and 24V systems
  • The externally-controlled slope for reduced RFI emissions
  •  Detection of ground fault (permanent Dominant) on TXD input
  • Power-on Reset and voltage brown-out protection
  • An unpowered node or brown-out event will not disturb the CAN bus
  • Low current standby operation
  • Protection against damage due to short-circuit conditions (positive or negative battery voltage)
  • Protection against high-voltage transients
  • Automatic thermal shutdown protection
  • Up to 112 nodes can be connected
  • High-noise immunity due to differential bus implementation
  • Temperature ranges:
    • Industrial (I): -40°C to +85°C
    • Extended (E): -40°C to +125°C
