CY545 Example Circuits

Three Example Cases

The three following circuit diagrams illustrate the wide choice of possibilities for CY545 applications circuits. In the first, only the serial command interface and the pulse and direction lines are used. This represents a minimal CY545 design. The second example is similar, but uses the parallel input bus to send commands to the CY545, with the pulse and direction lines still sent to a power driver. The third diagram illustrates a full blown system with RS-232 serial input, external memory, display circuits, thumbwheel interface, and I/O lines, and is implemented on the CYB-545 prototyping board.
