About the Integration Guide

This guide provides the information needed to integrate the MatchPort AR™ device

server within another product. The intended audiences are the engineers responsible

for integrating the MatchPort AR into their product.

Notes:

The MatchPort AR Demo Kit provides hardware and firmware for customer

evaluation. The complete kit includes a Module Universal Demo Kit

(Lantronix PN MP10010NMK-01) and a MatchPort AR sample (Lantronix PN

FP300200S-01)

For developing application firmware on MatchPort AR, there is a MatchPort

Plus Development board with a Background Debug Mode (BDM) connector.

Please contact Lantronix for more details.

Additional Documentation

The following guides are available on the product CD and the Lantronix Web site

(www.lantronix.com)

MatchPort AR User Guide Provides information needed to configure, use,

and update the MatchPort AR firmware.

MatchPortAR™IntegrationGuide 7

The MatchPort AR embedded device server is a complete network-enabling solution

on a 1.75"x1.75" PCB. This miniature device server empowers original equipment

manufacturers (OEMs) to go to market quickly and easily with networking and web

page serving capabilities built into their products.

The MatchPort AR has the following features:

Power Supply: Regulated 3.3V input required. There is a step-down

converter to 1.5 volts for the processor core. All voltages have LC filtering to

minimize noises and emissions.

Controller: A Lantronix DSTni-FX 32-bit microprocessor, running at 166

MHz internal bus and 83 MHz external bus.

Memory: 4 MB Flash and 8 MB SDRAM, and can be expanded. Please

contact your sales representative if you need higher memory densities.

Ethernet: 10/100 Base TX with auto-negotiation and HP auto-MDIX. On-

board 100-ohm terminations included. Users just need an RJ45 jack and 1:1

Ethernet magnetics with a minimal numbers of discrete components.

Integrated Ethernet LED Drivers: For connections to Ethernet Link and

Activities LEDs.

Serial Ports: Two full RS232 serial ports with all hardware handshaking

signals. Baud rates can be standard or customized up to 230 Kbps.

RS232/422/RS485 functionalities can also be configured on Serial Port 1.

Configurable IO Pins (CPs): Up to 7 pins are configurable as general

purpose I/Os if no DTR or DCD is used on serial ports.

Interface Signals: 3.3V-level interface signals.

Temperature Range: Operates over an extended temperature range.

MatchPort AR Pinouts

There are two headers of 1x20, 2-mm pin spacing. The odd row header is designated as P1;

pins are numbered 1 to 39. The even row header is designated as P2; pins are numbered

2 to 40.

Power and Ground

The MatchPort AR requires a regulated 3.3Vdc +/- 5% power input at P1.37 and

ground at pin P1.39.

Direct connection of 3.3V and ground on MatchPort AR to 3.3V power and ground

planes of the target board is recommended in place of heavy trace routing to

minimize noises as well as voltage drops at the connection.

Reset

The MatchPort AR reset pin RESETIN# is an input-only pin and connects to an 811-

type reset IC. This input is for a pushbutton switch type manual reset. If no external

reset control is desired, leave this pin floating.

2:Description and Specifications

MatchPort AR™ Integration Guide 10

There is an on board capacitor, 0.1uF to ground, at the RESETIN# to filter out

transient voltages. However, as always, it is a good practice to have RESETIN# trace

on the target board as short as possible to avoid reset occurrences when transient

voltages such as those caused by ESD are present.

Ethernet Connections

The MatchPort AR provides Ethernet interface transmit ETX and receive data ERX

connections from a PHY device. Thus, before presenting signals to the outside world

using an RJ45 jack, a 1:1 Ethernet Magnetics is needed to interface and to isolate

the unit. A recommended connection diagram to an RJ45 jack with integrated 1:1

Ethernet magnetics is shown below.

Figure 2-3. Connection Diagram to an RJ45 Jack

We recommend a low capacitance TVS diode array such as a Semtech SRV05-4 at

ETX+, ETX-, ERX+, ERX- if frequent transient voltages are present.
