Datasheet
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.
