Profile: Cybernetic Micro Systems provides application specific ICs to interface to a variety of peripherals that would be difficult to control from a general purpose computer. Our products include communication, instrument-size LCD & LED, step motor and miscellaneous controllers. Our CY233 local intelligent network controller provides a general mechanism for passing data between a serial network or computer port and local parallel devices. It operates in one of three basic modes, which determine the complexity of the connections and the format of the serial data.
