MCP2517FD click

MIKROE-2379

MCP2517FD click is a complete CAN solution which carries the MCP2517FD CAN FD controller and ATA6563 high-speed CAN transceiver from Microchip, as well as a DB9 9-pin connector.

The click requires both 3.3V and 5V power supply. It communicates with the target microcontroller through the SPI interface, with additional functionality provided by the following pins on the mikroBUS™ socket: AN, PWM, INT, TX and RX.

Note: For selecting the interface voltage level, use the onboard jumper, and choose between the 3.3V and 5V. For more information, see the Jumpers and Settings table below.



MCP2517FD features

The MCP2517FD is a cost-effective and small-footprint CAN FD controller that can be easily connected to a microcontroller over an SPI interface. Therefore, a CAN FD channel can be easily added to a microcontroller that is either lacking a CAN FD peripheral, or that doesn’t have enough CAN FD channels.

The MCP2517FD supports both, CAN frames in the Classical format (CAN2.0B) and CAN Flexible Data Rate (CAN FD) format.

ATA6563 CAN transceiver features

ATA6563 is a high-speed CAN transceiver that provides an interface between a controller area network (CAN) protocol controller and the physical two-wire CAN bus.

The transceiver is designed for high-speed (up to 5Mbit/s) CAN applications in the automotive industry, providing differential transmit and receive capability.

It offers improved electromagnetic compatibility (EMC) and electrostatic discharge (ESD) performance.

Connector features

This is a standard DB 9-pin male connector.
