MICROCHIP MCP2518FDT-E/SL

The MCP2518FD device is a cost-effective and small-footprint CAN FD controller 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. MCP2518FD 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 MCP2518FD device was improved as follows:

• Added Low Power Mode (LPM), in order to reduce leakage current to 10 μA over the full temperature range.
• Extended SEQ field in Transmit Message Object and Transmit Event FIFO Object from 7 to 23 bits.
• Added DEVID register to distinguish between future members of the device family.
• Switched to saw cut DFN package with wettable flanks.

• External CAN FD Controller with Serial Peripheral Interface (SPI)
• Arbitration Bit Rate up to 1 Mbps
• Data Bit Rate up to 8 Mbps
• CAN FD Controller modes - Mixed CAN 2.0B and CAN FD Mode - CAN 2.0B Mode
• Conforms to ISO 11898-1:2015
• 31 FIFOs, configurable as Transmit or Receive FIFOs
• One Transmit Queue (TXQ)
• Transmit Event FIFO (TEF) with 32 bit time stamp
• Message transmission prioritization: - Based on priority bit field - Message with lowest ID gets transmitted first using the Transmit Queue (TXQ)
• Programmable automatic retransmission attempts: unlimited, 3 attempts or disabled
• 32 Flexible Filter and Mask Objects
• Each object can be configured to filter either: - Standard ID + first 18 data bits, or - Extended ID
• 32-bit Time Stamp
