ASPC2 ASIC for PROFIBUS-DP
The Siemens 6ES7195-0AA11-0XA0 is an ASPC2 ASIC purpose-built for PROFIBUS-DP communication, supplied as a 66-piece stick.
What it does on a PROFIBUS-DP line
This ASIC handles the PROFIBUS-DP protocol processing at the physical and data-link layers, offloading the host CPU from real-time token-passing and frame handling. It is the silicon that makes a PROFIBUS-DP slave or master node work — without it, the bus interface cannot negotiate baud rates or manage cyclic data exchange.
