MICROCHIP MCP251863T-E/SS

The MCP251863 device is a cost-effective and small-footprint CAN FD controller (MCP2518FD) with an integrated Transceiver (ATA6563) that can be easily added to a microcontroller with an available SPI interface. A CAN FD channel can be easily added to a microcontroller that is either lacking a CAN FD peripheral or does not have enough CAN FD channels. MCP251863 supports both CAN frames in the Classical format (CAN2.0B) and CAN Flexible Data Rate (CAN FD) format, as specified in ISO 11898-1:2015. The integrated transceiver is a high-speed CAN FD Transceiver compliant with ISO 11898-2:2016 and SAE J2962-2 CAN standards. It provides a very low current consumption in Standby mode and wake-up capability via the CAN bus.
