The PROFIBUS DP ASICs allow equipment manufacturers to connect their devices to PROFIBUS easily.

They can be implemented at transmission rates of up to 12 Mbit/s.

The following blocks are available for different functional requirements and fields of application:

• Master applications:
  ASPC 2
• Intelligent slaves:
  SPC 3 and SPC3LV for PROFIBUS DP, with hardware-controlled bus access;
  DPC 31 with integral 8031 core;
  SPC 4-2.
• Connection in intrinsically safe systems:
  SIM 1-2 for physical connection in intrinsically safe fieldbus systems as a Medium Attachment Unit for IEC 61158-2 at 31.25 Kbit/s. Especially for combining with the SPC 4-2 and DPC 31.
• Simple slaves:
  LSPM 2 with 32 input/output bits for confined spaces
• Connection to fiber-optic conductors:
  FOCSI
  module for electrical conditioning of signals already received or to be sent. The module ensures that the optically transmitted signals are properly electrically restored (retiming/retriggering)

For initial development, order quantities of 5/6 ASICs are possible (not suitable for batch assembly because the pins of the ASIC can be bent due to the packaging; packing units larger than 5/6 units must be used)

The number of ASICs per packing unit depends on the ASIC type (see ordering data).

The ASICS ASPC 2, SPC3, SPC3LV, DPC31, LSPM2 and FOCSI can also be supplied in a lead-free design.
