PROFINET ASIC with integrated switch and ARM core
The 6ES7195-0BH33-0XA0 is the ERTEC 200P Step 3 — a PROFINET ASIC that handles Industrial Ethernet at 100 Mbps with an embedded ARM processor, a 2-port switch, and integrated PHYs on a single die. This is the silicon that drives the real-time Ethernet interface on Siemens ET 200SP and other distributed I/O stations.
Packaging and compliance for production runs
RoHS compliant since 19 December 2023, with REACH Article 33 candidate list disclosure available. Export control classification is AL:N / ECCN:N — no license required for standard industrial shipments. Packaging dimensions are 36.5 x 35.0 x 5.2 cm per reel. The product class is B — return restricted, meaning Siemens requires direct partner contact for any return or credit; this is normal for ASIC-level components. Group code R1DS and product group 4511 are the internal Siemens classification fields for this ASIC family — useful when cross-referencing against Siemens ordering documentation or legacy BOM structures.
What the ERTEC 200P Step 3 means for your design
The integrated 2-port switch and dual PHYs mean this single ASIC replaces what used to require a separate Ethernet controller, switch IC, and two PHY chips. That cuts BOM cost and board space, and simplifies the PCB layout by keeping the 100Base-TX signal paths inside the package. The ARM processor offloads PROFINET protocol handling from the host controller — the ASIC handles the real-time stack, so the main CPU sees only application data. This is the Step 3 revision, which includes bug fixes and performance improvements over earlier ERTEC 200P stepping levels.
