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 OEM Base Board

hardware design, which together form the LPC3250 Developer’s Kit.

Note that there is a previous version of the LPC3250 Developer’s Kit that was based on the QVGA

Base Board. This manual is for the new OEM Base Board (not the same as the QVGA Base Board).

2.1 Features

Embedded Artists’ LPC3250 OEM Board lets you get up-and-running quickly. The small form factor

OEM board offers many unique features that ease your learning curve and program development. The

board has 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

 32.768kHz RTC crystal

 256 Kbit I2C E2PROM for storing non-volatile parameters

 Buffered 16-bit data bus for external expansion

 Voltage translation buffers. 3.3V external bus can be used.

 100/10M Ethernet PHY/interface based on National/TI DP83848

 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 EMC performance

There is an accompanying OEM Base Board that can be used for initial prototyping work. The features

of the board are:

 Interfaces and Connectors

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

 LCD expansion connector with control signals for touch screen interface

 Expansion connector with all OEM Board signals

 Ethernet connector (RJ45)

 MMC/SD interface & connector
