General Description

The evaluation kit consists

  • PROFIBUS base board including RS485 and fiber optic interface
  • Extension board with Atmel 89C5132 microcontroller
    (USB C51-based Microcontroller, 64K Bytes Flash, InSystemProgrammable via USB)
  • PROFIBUS-DP V1/V2 Firmware (C source code)
  • Two additional VPC3+C ASICs for test purpose
  • complete plug´n´play PROFIBUS DP Slave unit based on VPC3+C including appropriate hard- and software (source code): the basic set for PROFIBUS newcomers to reduce development time and cost
