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.
