LPC2478 Developer's Kit - User's Guide

2 Introduction

Thank you for buying Embedded Artists‟ LPC2478 Developer's Kit based on NXP‟s ARM7TDMI-S
LPC2478 microcontroller.
This document is a User‟s Guide that describes the LPC2478 OEM Board (both 16- and 32-bit data
bus versions) and the QVGA Base Board hardware design. It is the User‟s Manual for both the
LPC2478 Developer's Kit as well as for just the LPC2478 OEM Board. There is a separate document
describing program development for the LPC2xxx series in general with Embedded Artists QuickStart
Build Environment.
