CYB-233 Overview

If you have a simple parallel to serial conversion or a more complicated ring networking scheme in mind, the CYB233 Network Prototyping kit will allow you to more quickly implement your design. Based on the CY233 control chip, the kit operates at up to 57600 baud, and includes all parts needed to assemble a working CY233 interface. This includes both the serial and parallel interfaces: the RS-232-C connector, line driver and receiver, and the address decoding logic for the parallel device. A 40-pin pattern has been added to accommodate an optional CYxxx parallel device, and about 30% of the board is designed as a wirewrap area to implement your own design or application circuitry.
