2 Introduction

Thank you for buying Embedded Artists’ LPC3250 Developer’s Kit based on NXP’s ARM926EJ-S

LPC3250 microcontroller.

This document is a User’s Guide that describes the LPC3250 OEM Board and the QVGA Base Board

hardware design. It is the User’s Manual for both the LPC3250 Developer’s Kit as well as for just the

LPC3250 OEM Board.

2.1 Features

Embedded Artists’ LPC3250 Developer’s Kit with NXP’s ARM926EJ-S LPC3250 microcontroller lets

you get up-and-running quickly. The small sized OEM board offers many unique features that ease

your learning curve and speed up your program development. The board has also been designed for

OEM applications with volume discount available. The features of the LPC3250 OEM Board are:

 NXP's ARM926EJ-S LPC3250 microcontroller in BGA package, with 256 KByte internal RAM

 External data memory: 64 MB DDR SDRAM (16-bit databus width)

 External FLASH memories: 128 MB (1Gbit) NAND FLASH and 4 MB (32Mbit) SPI-NOR

FLASH

 13.0000 MHz crystal for cpu

 256 Kbit I2C E2PROM for storing non-volatile parameters

 Buffered 16-bit data bus for external expansion

 200 pos expansion connector (SODIMM-200 format, 0.6mm pitch)

 Almost all LPC3250 pins available (except dedicated pins for on-board memories and

internal powering)

 3.15-3.3V powering

 Onboard reset generation

 5 LEDs

 Compact SODIMM size: 66 x 48 mm

 Eight layer PCB design for compact design and best noise immunity

There is an accompanying QVGA Base Board that can be used for initial prototyping work. This base

board was originally developed for the LPC2478 processor and the associated LPC2478 OEM Board

in SODIMM format. Some interfaces, for example the CAN bus and ETM, do not exist on the LPC3250

and can hence not be used. The features of the QVGA Base Board are:

 3.2 inch QVGA TFT color LCD with touch screen (4-wire version)

 18-bit RGB interface to display

 Connectors

 200 pos, 0.6mm pitch SODIMM connector for the LPC3250 OEM Board

 Expansion connector with all LCD controller signals, for custom displays

 Expansion connector with all SODIMM interface signals

 Ethernet connector (RJ45)

 CAN interface & connector (cannot be used with the LPC3250 OEM Board)

 MMC/SD interface & connector
