ASIC SPC 2 for PROFIBUS DP — 1.5 Mbit/s bus interface
The Siemens 6ES7195-0BC30-0XA0 is the SIMATIC DP ASIC SPC 2, a dedicated PROFIBUS DP interface chip that handles the full DP protocol stack on-chip. It supports the maximum PROFIBUS DP transmission rate of 1.5 Mbit/s and provides a 244-byte telegram memory buffer for process data exchange. This ASIC is the core of a PROFIBUS DP slave node — it manages bus timing, data consistency, and diagnostic handling without loading the host CPU. The 244-byte telegram memory limits the total input plus output data per slave to that size, which is standard for many distributed I/O and drive profiles.
Lifecycle and sourcing — active production, quoted to order
The standard delivery quantity is 4,500 pieces per order unit, reflecting its typical supply as a production component for OEMs building PROFIBUS DP slave devices.
Integration note — no programming, direct drop-in for SPC 2 designs
The ASIC SPC 2 is a hardware protocol engine — it requires no firmware or software configuration beyond the standard PROFIBUS DP parameter assignment from the master during startup. It is pin-compatible with earlier SPC 2 variants in the same package, so a board-level swap is straightforward if the existing layout already includes the SPC 2 footprint. The part is designed for surface-mount assembly on a PROFIBUS DP slave PCB. The 1.5 Mbit/s rate is the bus speed limit; the ASIC automatically adapts to the baud rate set by the DP master during bus parameterisation.
