Introduction

This user's manual details the setup and configuration of
the NXP S32R274 Evaluation Board (hereafter referred to
as the EVB). The EVB is intended to provide a
mechanism for easy customer evaluation of the S32Rxx
family of microprocessors, and to facilitate hardware and
software development.
At the time of writing this document, the S32Rxx family
form the basis of the RADAR specific 55nm devices. For
the latest product information, please speak to your NXP
representative or consult the S32Rxx website at
www.nxp.com.
The EVB is intended for bench / laboratory use and has
been designed using normal temperature specified
components (+70°C).
