The Siemens 6ES7195-0EA00-0XA0 is a dedicated ASIC (FOCSI – Fiber Optic Controller for Siemens) for preprocessing PROFIBUS fiber optic signals. It operates on a 3.3 V DC supply, handles transmission rates up to 12 Mbit/s, and is housed in a 44-pin TQFP package. Power dissipation is low at 0.75 W, which keeps thermal management simple on a crowded board. Given its role as a Medium Management Unit for PROFIBUS FO, this ASIC handles the signal conditioning and framing that frees the main CPU from byte-level timing. No external firmware is required; the logic is fixed in silicon.

Product details
Frequently asked questions
What is the ASIC type in this part?
The ASIC is FOCSI, which stands for Fiber Optic Controller for Siemens. It preprocesses signals for PROFIBUS fiber optic communication.
What is the maximum operating temperature?
The part is rated from -40 °C to 85 °C ambient, so it can handle both freezing and hot environments typical in industrial panels.
Will the 6ES7195-0EA00-0XA0 drop into a panel specified around 6AG1677-2AA40-4AA0?
No. The 6AG1677-2AA40-4AA0 is an industrial PC with a processor, memory, and Ethernet interfaces – a completely different product class. This ASIC is a surface-mount IC for a PROFIBUS FO interface board and serves a different function.
