    Customer Comment

    Theon Sensors' night vision system uses the CAN Bus Controller IP core from CAST, Inc."The CAST CAN core has been successfully integrated into our new night vision camera product which have been already shipped to one of our customers.

    The configuration of the core you have provided fit perfectly with our requirements so we decided to use it as is without any modification.

    Overall, I think that the core's performance was excellent, while the detailed documentation contributed a lot to the fast integration of the core into our system.“
    — Nikos Vassiliadis, Electronics Engineer, Theon Sensors


    CAST is a member of the CAN in Automation (CiA) user's and amnufacturer's trade group.

    CAN-CTRLCAN 2.0 & CAN FD Bus Controller Core

    Implements a CAN protocol bus controller that performs serial communication according to CAN 2.0, and CAN FD specifications. It supports the original Bosch protocol and ISO specifications as defined in ISO 1989—including time-triggered operation (TTCAN) as specified in ISO 19898-4—and is also optimized to support the popular AUTOSAR and SAE J1939 specifications.

    The CAN-CTRL bus controller is part of the automotive IP cores line from CAST, Inc.The CAN protocol uses a multi-master bus configuration for the transfer of frames between nodes of the network and manages error handling with no burden on the host processor. The core enables the user to set up economic and reliable links between various components. It appears as a memory-mapped I/O device to the host processor, which accesses the CAN core to control the transmission or reception of frames.

    The CAN core is easy to use and integrate, featuring programmable interrupts, data and baud rates; a configurable number of independently programmable acceptance filters; and a generic processor interface or optionally an AMBA APB, or AHB-Lite interface. It implements a flexible buffering scheme, allowing fine-tuning of the core size to satisfy the requirements of each specific application.

    CAN 2.0/FD bus controller IP coreThe number of receive buffers is synthesis-time configurable. Two types of transmit buffers are implemented: a high-priority primary transmit buffer (PTB) and a lower-priority secondary transmit buffer (STB). The PTB can store one message, while the number of included buffer slots for the STB is synthesis-time configurable 0 to 16 slots. An optional wrapper instantiating multiple CAN controller cores easies integration in cases where multiple bus-nodes need to be controlled by the same host processor.

    The core implements functionality similar to the Philips SJA1000 working with its PeliCAN mode extensions, providing error analysis, diagnosis, system maintenance, and optimization features.

    CAN bus verification IP (VIP) is availableThe CAN core is extensively verified and proven in multiple production designs. CAN bus verification IP (VIP) is also available for this core, for comprehensive verification of the core and its function within a system.

    A 30-day free license for the CAN-Xactor Verification IP is included
    with each CAN-CTRL Controller Core delivery.

    This core can be mapped to any any Intel, Lattice, MicroSemi, or Xilinx programmable device, or to any ASIC technology, provided sufficient silicon resources are available. Please contact CAST Sales to get accurate characterization data for your specific implementation requirements. Meanwhile, we provide the following representative results (each in a new pop-up window):

    The CAN-CTRL core can be integrated in devices that use CAN or higher-layer, CAN-based communication protocols. In addition to traditional automotive applications, such devices are used in industrial (e.g. the CANopen and DeviceNet protocols), aviation (e,g. the ARINC-825 and CANaerospace protocols), marine (e.g. the NMEA 2000 protocol) and other applications.
