VPC3+CLF PROFIBUS DP Slave Controller ASIC with new features

This component is based on the VPC3+CLF that has been available since 2003 and, in addition to the known characteristics (DP-V0/V1/V2 functions, 4Kb RAM memory and 5V/3.3V power supply), offers the PROIFBUS-DP-V2 specified service “Time synchronization”. In particular, applications with increased security requirements need the support of this function in the chip, in order to be able to provide precise timestamps for all events throughout the system or to be able to trigger time-synchronized control functions. A further goal was to reduce power consumption in comparison to existing components.

An enhanced version of the introduced software stack is available that makes using the new functions user-friendly. Corresponding software versions are also offered, to support redundant slave applications with one or two micro-controllers.

This means that Profichip GmbH offers the only “pure” Slave Controller with this function scope in two different versions.

The first samples will be available from the end of Q1, 2008. Serial production will follow from the middle of April.
