INTRODUCTION

The Smart Power Switch Controller Evaluation Board SPSC-EVB provides users with a convenient and flexible
platform from which to evaluate the manifold features and functions available with the UT36PFD103 SPSC. The
SPSC-EVB may be operated in single-supply stand-alone form (i.e. without host microcontroller) and in full-
featured operation when installed as an ARDUINO shield onto a compatible host microcontroller evaluation board.
To facilitate rapid evaluation, Cobham provides software API for the UT32M0R500 Arm M0+ evaluation board to
service the SPSC host controller along with a run-time executable graphical user's interface (GUI). Refer to the
SPSC_SoftwareUsersGuide.pdf for documentation on GUI operation. Additionally, the UT32M0R500 software API
is available for download on the Cobham Webpage
arm.cfm) along with an application note detailing how to program the UT32M0R500-EVB.
