Lead-free ASIC for PROFIBUS DP slave nodes
The Siemens 6ES7195-0BA22-0XA0 is a lead-free ASIC implementing the PROFIBUS DP slave protocol at up to 12 Mbit/s, supporting 32 I/O points. It is the LSPM2 (Low-Speed Profile Master/Slave) variant, designed for integration into SIMATIC DP distributed I/O stations and third-party DP slave devices that require a certified protocol engine.
12 Mbit/s data rate and 32 I/O capacity
The ASIC handles the full PROFIBUS DP baud rate range up to 12 Mbit/s, matching the bus speed of the DP master. The 32 I/O count defines the maximum process data width per slave node — this is the address space the master allocates in its cyclic I/O map. For applications requiring more than 32 bytes of input or output data, multiple LSPM2 nodes or a higher-tier ASIC (e.g., the ASPC2) would be needed.
