SERC816

Controllers Overview

The SERC816 is a telecommunications interface integrated circuit designed for SERCOS (Serial Real-time Communication System) interface communication systems. It serves as the direct link between electro-optical transceivers and microprocessors, handling hardware-related functions to reduce system costs and processing time. The device supports serial interface operation up to 16 Mbaud without external circuitry and includes a dual port RAM of 2048 x 16 bits for control and communication data. It operates within a supply voltage range of 4.75 V to 5.25 V and functions at temperatures from -40°C to +85°C. Packaged in a PQFP-100 format, it facilitates synchronous data exchange in distributed control environments.
