VPC3+C - PROFIBUS-DP Slave Controller (100% SPC3 compatible)

SPC3 can be easily replaced with even more features.

profichipĀ“s VPC3+C is a communication chip with 8 Bit Microprocessor interface for intelligent PROFIBUS slave applications. 

Available versions of the chip:

  • PROFIBUS Slave Controller ASIC VPC3+CLF3

    (order code PALF2080)


Features VPC3+C

  • Pin, function and software compatible with SPC3 from Siemens
  • Supporting PROFIBUS DP-VO, DP-V1 & DP-V2 protocol
  • 4 KB communication RAM
  • Optional 5V or 3,3V supply voltage
  • Low power consumption
  • Software stack and Evaluation-Kit available
  • Package PQFP 44 (RoHS compliant)
  • DP-V2 clock synchronisation
  • 20% reduced current consumption

The VPC3+CLF3 handles the message and address identification, the data security sequences and the protocol processing for PROFIBUS-DP. In addition the acyclic communication and alarm messages, described in DPV1 extension, are supported. Furthermore the slave-to-slave communication Data eXchange Broadcast (DXB) and the Isochronous  Mode (IsoM), described in DPV2 extension, are also provided.

Automatic recognition and support of data transmission rates up to 12 Mbit/s, the integration of the complete PROFIBUS-DP protocol, 4 KByte communication RAM and the configurable processor interface are features to create high-performance PROFIBUS slave applications. The device can be operated with either 3.3V or 5V single supply voltage.

VPC3+CLF3 is pin-compatible to SPC3 ASIC from SIEMENS. Therefore, VPC3+CLF3 can replace SPC3 in existing applications along with improved functionality. See cross-reference list below:
