The CC175 dual channel Controller Area Network (CAN) interface provides a flexible and powerful connection from the VMEbus to the CAN network. The module contains two separate CAN network interface connections, each having its own controller and accompanying physical network interface.
The CAN controllers are capable of handling all CAN functions on-chip. The optical isolated physical interface is conform the ISO/DIS 11898 standard using the 82C250 CAN transceiver. To provide additional protection the interface is optically isolated using on-board optocouplers and DC/DC converters.
To satisfy specific interface requirements, the standard physical interface can be bypassed using a mezzanine module or a VMEbus P2 transition module. The mezzanine option also allows the board to be connected to the TCANnector adapter. This is a general purpose adapter which can be used to connect the CC175 to any existing CAN network in a very flexible way, independent of the physical interface used.
The on-board MPU eases the integration of the CC175 in a VMEbus system. DualPorted memory in combination with mailbox interrupts supports an extensive set of software options. These include both low-level CAN functions as well as standard higher protocol software layers.
