Working Principles

The MCP2510T-I/ST operates as a stand-alone CAN controller, facilitating communication between various ECUs in automotive systems. It interfaces with a microcontroller through the SPI interface, enabling the exchange of data over the CAN bus.

When a message is received, the MCP2510T-I/ST checks its acceptance filters and masks to determine if it should be stored in one of the receive buffers. If the buffer is full, an interrupt signal is generated to notify the microcontroller.

For transmission, the microcontroller writes the message data into one of the transmit buffers and requests transmission by setting the corresponding RTS (Request-to-Send) pin. The MCP2510T-I/ST then sends the message over the CAN bus.

Detailed Application Field Plans

The MCP2510T-I/ST finds extensive application in the automotive industry, particularly in the following areas:

1. Engine Control Units (ECUs)
2. Transmission Control Units (TCUs)
3. Body Control Modules (BCMs)
4. Anti-lock Braking Systems (ABS)
5. Airbag Control Units (ACUs)
6. Instrument Clusters
