CY527 Special Purpose Stepper Motor Controller

CY527 Overview

The CY527 (and CY527J) Stepper Motor Controller is a custom modification of the CY525 controller, implemented in newer technology. While the stored program capability and on-the-fly features have been removed, many of the other CY525 software and hardware features remain implemented, but in a different pin configuration.
