DPC31 – PROFIBUS DP/PA protocol ASIC
SAR Pack of 6 DPC31 ASICs – € 95.-
SAR Pack of 66 DPC31 ASICs – € 868.-
SAR Pack of 660 DPC31 ASICs – € 7.350.-

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.

Remarks

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.
