All information contained herein is provided “AS IS.” Lantronix undertakes no obligation
to update the information in this publication. Lantronix does not make, and specifically
disclaims, all warranties of any kind (express, implied or otherwise) regarding title, non­infringement, fitness, quality, accuracy, completeness, usefulness, suitability or

whatsoever to any user for any damages, losses and causes of action (whether in

contained in this document are subject to change without notice.

This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one of the following measures:

xPico® Embedded Device Server Integration Guide 2

1. Reorient or relocate the receiving antenna.

2. Increase the separation between the equipment and receiver.

3. Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.

4. Consult the dealer or an experienced radio/TV technician for help.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following
two conditions: (1) This device may not cause harmful interference, and (2) this device
must accept any interference received, including interference that may cause undesired
operation.

This device is intended only for OEM Integrators. The OEM integrator should be aware of
the following important issues.

Labeling of the End Product (xPico Wi-Fi units only)

The label on the end product incorporating the xPico Wi-Fi module must clearly state that
it contains an FCC-approved RF module. Canada and Japan also require a similar
statement.

For example, “This product contains RF transmitter ID # (put FCC, IC, and/or Japan
module grant numbers here).” The label must include the ID numbers for the regions
where the end product is installed. The grant numbers are below.

 xPico Wi-Fi FCC ID number: R68XPICOW

 xPico Wi-Fi IC ID number: 3867A-XPICOW

 xPico Wi-Fi Japan ID numbers: 201-135275

RSS-GEN Sections 7.1.4 and 7.1.5 Statement for Devices with Detachable Antennas (xPico
Wi-Fi units only)

This device has been designed to operate with the antennas listed in the Certificate, and
having a maximum gain of 2.88 dBi. Antennas not included in this list or having a gain
greater than 2.88 dBi are strictly prohibited for use with this device, unless system level
FCC approval is gained. The required antenna impedance is 50 ohms.

To reduce potential radio interference to other users, the antenna type and its gain
should be so chosen that the equivalent isotropically radiated power (EIRP) is not more
than that required for successful communication.

Integration Notes (xPico Wi-Fi embedded device server):

 This module is authorized under limited module approval specified to mobile host

equipment. So, the antenna must be installed such that 20cm is maintained between
the antenna and users.

 The transmitter module may not be co-located with any other transmitter or antenna.
 As long as the two conditions above are met, further transmitter testing will not be

required. However, the OEM integrator is still responsible for testing their end product
for any additional compliance requirements required with this module installed (for
example, digital device emission, PC peripheral requirements, etc.)

 In the event that these conditions cannot be met (for example certain laptop

configurations, general purpose PCMCIA or similar cards, or co-location with another
transmitter) and obtaining a separate FCC authorization will be required, then the
FCC authorization is no longer considered valid and the FCC ID cannot be used on
the final product (including the transmitter).

 Changes or modifications to this device not explicitly approved by Lantronix will void

the user's authority to operate this device.

About the Integration Guide

This user guide provides the information needed to integrate the Lantronix® xPico®
embedded device servers into customer-printed circuit boards. This manual is intended
for engineers responsible for integrating the xPico embedded device server into their
product.

Note: This document includes support for xPico embedded device server

versions XPC100100B-01, XPC100100S-01, XPC100100K-02, XPC10010MB-01
and XPC10010MS-01, and xPico Wi-Fi embedded device server versions
XPW100100B-01, XPW100100S-01 and XPW100100K-02. For integration
information for the Lantronix xPico Wi-Fi SMT embedded device server modules,
XPCW1002 and XPC@10003, please reference document 900-714 xPico Wi-Fi
SMT Embedded Device Server Integration Guide.

The sections in chapter 2 provide board schematic and layout recommendations for both
xPico (wired) and xPico Wi-Fi® products. Some of the sections apply to xPico (wired)
only or xPico Wi-Fi units only. Signals that are unused for a particular product can be left
floating. If the application has the potential to use both components as a stuff option it is
recommended to follow the design guide for all of the sections. The table below lists
which sections are applicable to the xPico (wired) and xPico Wi-Fi products.

Note: “xPico” (wired) refers to the Ethernet-only versions of xPico embedded

device server.

2. Functional Description

Designed for quick integration with minimal engineering effort, the chip-sized xPico
embedded device server provides simplicity and flexibility making it the easiest and
fastest networking-enabling module on the market.

xPico and xPico Wi-Fi device servers are extremely compact networking solution that
enables Ethernet or Wireless connectivity on virtually any device with a serial interface.
The included industry-proven Lantronix device server application and full IP stack allow
seamless remote access to device data simplifying design integration while providing
robust connectivity.

As one of the smallest embedded device servers in the world, xPico and xPico Wi-Fi
embedded device servers can be utilized in designs typically intended for chip solutions.
A key difference with the xPico device server is that there is virtually no need to write a
single line of code, translating to a much lower development cost and faster time-to­market.

xPico Features

The xPico device server contains Lantronix’s own DSTni® EX controller, with 256 KBytes
of SRAM, 16 KBytes of boot ROM, and integrated 10/100 PHY.

The xPico embedded device server also contains the following:

 3.3-volt serial interface
 8 Configurable I/O pins
 All logic level I/O pins are 5V input tolerant
 4-Mbit flash memory
 Power supply filters
 Reset circuit
 +1.8V regulator

Note: The xPico embedded device server does not contain integrated Ethernet

magnetics. An external Ethernet magnetic module and RJ45 Jack is required to
interface to a standard 10/100Mbps Ethernet network.

The xPico unit requires +3.3-volt power and is designed to operate in an extended
temperature range (see technical data).

2: Functional Description

xPico Wi-Fi Features

The xPico Wi-Fi device server contains Cortex M3 ARM processor with 128KByte of
SRAM and 1MByte of embedded Flash memory. The unit also includes an 802.11 b/g/n
WLAN radio with a U.FL port for connection to an external antenna.

The xPico Wi-Fi embedded device server also contains the following:

 3.3-volt serial interface
 8 Configurable I/O pins
 All logic level I/O pins are 5V input tolerant
 8-Mbit flash memory (in addition to the 1MByte CPU embedded Flash)
 Power supply filters
 Reset circuit

Note: xPico Wi-Fi units do not contain an integrated antenna. An external

antenna is required for connection to a WLAN network.

The xPico Wi-Fi embedded device server requires +3.3-volt power and is designed to
operate in an extended temperature range (see technical data).
