DPC31 - PROFIBUS DP/PA protocol ASIC

The DPC31 protocol ASIC mainly consists of a PROFIBUS controller with more RAM than a SPC3 and additionally an integrated 8031 core. The big advantage is saving in hardware costs since a controller is already integrated.

For PA designs the integrated 8031 is NOT sufficient because of the demanding profile software (code size). In this case a Mitsubishi M16C62/M16C60 processor with the DPC31 is a good combination.
