The CANSPI is an easy-to-use, compact accessory board that lets you connect a CAN (Controller Area Network) bus to any microcontroller with Serial Peripheral Interface (SPI). The board employs both an MCP2515 CAN controller and an MCP2551 CAN transceiver. The MCP2515 circuit as a CAN controller allows for data exchange with microcontrollers using a standard SPI communication interface. On the other hand, the transceiver MCP2551 chip provides necessary signal adjustments and allows the signals to be sent/received at a 1 Mb/s. The CANSPI board allows transmitting and receiving standard and extended data and remote frames.
It makes an ideal option for users looking to connect CAN to a microcontroller without integrated CAN support. Applications like industrial automation, home automation, and the automotive and mobile machine industry are well-suited for the CANSPI board.
MCP2515 CAN Controller
MCP2515 is a stand-alone Controller Area Network (CAN) controller that is capable of transmitting and receiving both standard and extended data and remote frames. It communicates with MCUs using the industry standard SPI interfaces. The CAN controller comes with two acceptance masks and six acceptance filters to filter out unwanted messages. Hence, it also minimizes the host microcontrollers overhead.
MCP2551 CAN Transceiver
MCP2551 is a high-speed, fault-tolerant CAN transceiver that serves as an interface between a CAN protocol controller and the physical bus. Fully compatible with the ISO-11898 standard, it functions at 1 Mb/s speed and provides differential transmit and receive capability for the CAN controller.
