Working Principles

The MCP2515-E/MLVAO acts as a bridge between a microcontroller and a Controller Area Network (CAN) bus network. It communicates with the microcontroller through a high-speed Serial Peripheral Interface (SPI). The MCP2515-E/MLVAO supports the CAN V2.0B protocol and can handle both Standard and Extended Identifier Formats.

The device has multiple transmit and receive buffers, allowing for efficient data handling. It also provides error detection and flagging capabilities to ensure reliable communication on the CAN bus. The MCP2515-E/MLVAO can enter sleep mode to minimize power consumption when not actively transmitting or receiving data.
