The SERCON ASICs are application-specific integrated circuits for Sercos I and II. While their use is not mandatory, the ASICs contain all the hardware-related functions of the Sercos interface, and considerably reduce the hardware costs for a design. They feature the capability to perform all sequencing and synchronization tasks, relieving the host microprocessor of these time-intensive functions. The ASIC is the direct link between the fiber-optic receiver
and transmitter and the microprocessor that executes the control algorithms in a Sercos interface device. The same SERCON ASIC is used both for Sercos interface masters and slaves.
The current Sercos interface ASIC is the SERCON816, manufactured by STMicroelectronics in the 0.5 µm/5V HCMOS technology. It operates at 2/4/8/16 Mbit/sec and is downward compatible with the now obsolete SERCON410B (2/4 Mbit/sec) ASIC.
