PROFIBUS DP ASIC — signal integrity anchor
The Siemens 6ES7195-0BC20-0XA0 is the SIMATIC DP ASIC SPC 2, the silicon core that handles the PROFIBUS DP protocol stack on the slave side. It runs at a maximum transmission rate of 1.5 Mbit/s and carries a 244-byte telegram memory, which defines the data payload per bus cycle. The ASIC's job is to keep the DP line noise-resistant and deterministic. If you're chasing a phantom PROFIBUS fault, check the shield and the bus terminator first — the ASIC itself, when correctly powered and clocked, is a known-good interface point.
Each tray box ships 450 pieces. We can quote the 6ES7195-0BC20-0XA0 against your BOM line; lead time is quoted to your schedule via RFQ.
