Arasan’s CAN IP Controller Core performs serial communication as per CAN IP 2.0 Specifications. It supports full CAN IP 2.0 (both CAN IP 2.0A and 2.0B). The design implements the BOSCH CAN IP Message Transfer Protocols 2.0A (which is equivalent to CAN IP 1.2 and covers standard message formats with 11-bit identifiers); and 2.0B which covers both standard and extended message formats (both 11-bit and 29-bit identifiers). Arasan’s CAN IP Controller core is easy to integrate with the Host processor using an AMBA-AHB standard interface. This highly configurable design supports programmable Interrupts, data and baud rates, acceptance filters & buffering schemes specific to the application
