PC-104 CAN Interface CPC-104I

Special Features

  • Active PC-104 based CAN interface with local preprocessing by integrated microcontroller
  • One CAN channel, equipped with CAN controller NXP SJA1000
  • Microcontroller Dallas DS80C320, 32kByte SRAM, 64kByte flash
  • Firmware resident in flash, programmable within the system, adaption possible
  • Driver for MS-DOS and Windows 3.1/95/98/NT/2000/XP available


CPC–104I is a CAN interface module for PC–104 based systems with integrated microcontroller for the CAN bus. Designed for industrial series applications it has a robust and cost efficient construction. CPC–104I is available with galvanic separation and internal power supply of the CAN transceivers. Due to the internal buffering of CAN messages CPC–104I qualifies especially for use with operating systems where latencies are not exactly specified (e.g. MS Windows). The message oriented interface is designed in particular for applications, that have to capture a substantial part of the bus traffic, such as control and visualisation systems. Alternatively to the operation with standard software provided with the delivered device CPC–104I also offers the possibility to execute application specific firmware. For special application needs, a 64kByte flash ROM and a 32kByte SRAM are provided. The on board microcontroller Dallas DS80C320, compatible with industrial standard 8051, but considerably more powerful, allows the use of existing knowledge and development tools for many users.
