Microchip Technology, Inc. Integrated Circuits (ICs) - Interface - Controllers MCP2517FD-H/JHA

The MCP2517FD is an external CAN FD controller designed for integration with microcontrollers via an SPI interface. It supports arbitration bit rates up to 1 Mbps and data bit rates up to 8 Mbps, accommodating both CAN 2.0B and CAN FD modes as per ISO 11898-1:2015 standards. The device features 31 configurable message FIFOs, a transmit queue, and a transmit event FIFO with a 32-bit timestamp for efficient message handling. Operating within a supply voltage range of 2.7V to 5.5V, the MCP2517FD has a maximum active current of 20 mA and a low sleep current of 10 ¬µA. It includes 32 flexible filter and mask objects for message reception, allowing for detailed filtering based on standard or extended IDs. The controller also provides bus health diagnostics, error counters, and supports programmable automatic retransmission attempts. The MCP2517FD is rated for a wide operating temperature range of -40¬8C to +150¬8C, making it suitable for various industrial applications. It is available in a compact 14-pin VDFN package, which includes GPIO pins that can be configured for general-purpose I/O. This product is ideal for engineers looking to add CAN FD capabilities to microcontrollers lacking native support.
