The CAN2.0 IP controller implements the BOSCH CAN message transfer protocols 2.0A and 2.0B.

Specification 2.0A (which is equivalent to CAN 1.2) covers standard message formats (11-bit identifier); Specification 2.0B covers both standard and extended message formats (both 11-bit and 29-bit identifiers).


  • Supports full CAN (CAN 2.0 A and CAN 2.0B)
  • Broadly compatible with a Philips SJA1000
  • Supports both 11-bit and 29-bit identifiers
  • Supports bit rates from less than 125Kbaud to more than 1Mbaud
  • 64 byte Receive FIFO
  • Acceptance filtering
  • Single-shot transmission option
  • Listen-only mode
  • Reception of own messages
  • Error interrupt generated for each CAN bus error
  • Arbitration lost interrupt with record of bit position
  • Read/write error counters
  • Programmable error limit warning
