1. Out of the Box

The NXP analog product development boards provide an easy-to-use platform for evaluating NXP products. The boards support a range of analog, mixed-signal and power solutions. They incorporate monolithic integrated circuits and system-in-package devices that use proven high-volume technology. NXP products offer longer battery life, a smaller form factor, reduced component counts, lower cost and improved performance in powering state-of-the-art systems.

This page will guide the user through the process of setting up and using the RD33774PC3EVB board.

Working with the UJA1023-EVB (UJA1023 remote-controlled LIN I/O responder) requires a LIN commander board as additional hardware.

1.1 Kit contents

  • UJA1023-EVB in an antistatic bag
  • Quick Start Guide

1.2 Additional Hardware

The following hardware is necessary, but not included in this kit:

  • 12 V power supply
  • LIN bus cable
  • LIN commander

The following is a selection of LIN commander hardware options:

  • LIN interface tools
  • S32K116EVB: S32K116-Q048 evaluation board for automotive general purpose
  • S32K144EVB: S32K144-Q100 evaluation board for automotive general purpose
  • S32K312MINI-EVB: S32K312MINI-EVB evaluation board for automotive general purpose
  • S32K3X4EVB-T172: S32K3X4EVB-T172 evaluation board for automotive general purpose

1.3 Assumptions

Basic knowledge of the LIN Diagnostic and Configuration Specification from LIN Specification Package Revision 2.0, September 2003, is expected.
