RN171
1.0 DEVICE OVERVIEW
The RN171 is a standalone, embedded 802.11 b/g
Wireless Local Area Network (WLAN) module. The
module incorporates an on-board TCP/IP networking
stack, cryptographic accelerator, power management
subsystem, real-time clock, versatile sensor interface,
2.4 GHz transceiver, and RF power amplifier (see
Figure 1-1). With the RN171, designers can embed
Wi-Fi and networking functionality rapidly into virtually
any device.
The RN171 provides cost and time-to-market savings
as a self-contained internet-enabling solution. The
module has been designed to provide designers with a
simple Wi-Fi solution that features:
• Ease of integration and programming
• Vastly reduced development time
• Minimum system cost
• Long battery life
• Maximum value in a range of applications
The RN171 is configured with a simple ASCII com-
mand language. The “WiFly Command Reference,
Advanced Features and Applications User's Guide”
(DS50002230) contains a complete listing and
instructions of the ASCII command interface.
In the simplest configuration, the module requires only
power, ground, and UART TX and RX connections.
The RN171 module can interface to low-cost microcon-
trollers using only two wires, UART TX and RX.
The RN171 has a versatile sensor interface that can be
used to monitor analog signals such as temperature,
audio, motion, and acceleration.
The module has a small form factor, which makes it
easy to integrate. Additionally, the module is compati-
ble with standard pick-and-place equipment.
The RN171 is ideal for a vast range of applications that
require long battery life, moderate processing power,
moderate data throughput and occasional Wi-Fi
connectivity, such as:
• Real-Time Locationing Systems (RTLS)
• Industrial and home automation
• Health and fitness monitoring
• Telemetry
•Security
Additionally, the module is perfect for mobile wireless
applications such as asset monitoring and sensor
applications.
The RN171 can independently maintain a low-power
wireless network connection. Ultra-low power usage
and flexible power management maximize the mod-
ule’s lifetime in battery-operated devices. A wide oper-
ating temperature range allows use in indoor and
outdoor environments (industrial temperature range).
When operating in Sleep mode, the module minimizes
battery usage while still being able to respond to certain
events, including internal timers and events on the sen-
sor interfaces. Applications that make efficient use of
the sleep state can extend battery life to multiple years.
The RN171 has modular device approval for operation
in the United States (FCC) and Canada (IC). The
RN171 module is an R&TTE Directive assessed radio
module for operation in Europe.

RN171
2.0 CIRCUIT DESCRIPTION
(HARDWARE INTERFACE)
The following sections describe the module’s hardware
interface.
2.1 UART Interface
The UART interface supports 2-wire (RX, TX) and
4-wire configurations with hardware flow control (RX,
TX, CTS, and RTS). The logic levels are CMOS voltage
levels (not RS-232 voltage levels). The UART interface
supports baud rates of 2,400; 4,800; 9,600; 19,200;
38,400; 115,200; and 230,400 bits per second. Refer to
the “WiFly Command Reference, Advanced Features
and Applications User's Guide” (DS50002230) for
UART configuration information.
2.2 SPI Master Interface
The RN171 module contains a master SPI interface
(SPI_CS, SPI_CLK, SPI_MISO, and SPI_MOSI) that is
connected to an internal Flash memory. Do not connect
these pins on the host PCB.
2.3 SDIO Client Inter face
The RN171 modules contain an SDIO client with
SD-SPI mode and interface (SD_CLK/SCLK,
SD_D3/SS, SD-D2, SD_D1/INT, SD_D0/MISO, and
SD_CMD/MOSI). This interface is not currently imple-
mented in the WiFly command reference.
2.4 In-System Programming (ISP)
The ISP_TX, ISP_RX, and other pins allow in-system
programming of the module. The module’s firmware
can be upgraded via ISP using a *.bin file.
Though it is optional, it is recommended to place the
ISP header on the host PCB to facilitate firmware
upgrades during development and manufacturing. The
header is two row by 8-pin with 0.050 inch space and
pitch (Samtech P/N FTSH-108-01-F-DV-K). Refer to
Figure 3-3 for information about connecting to the mod-
ule for ISP. The RN-ISP in-system programming inter-
face connects to the module for ISP. Refer to the
RN-ISP product page on the Microchip web site for
more information.
2.5 Analog Sensor Interface
Sensors (0-3) can be used to wake the module. The
sensor pins are 1.2V tolerant. When sensor pins are
used as sensor inputs, they accept input voltages up to
1.2V but saturate at 400 mV.
The 14-bit ADC requires a 35 ms conversion time with
0.01% linearity.
Additionally, the module has a low-power interface for
interfacing sensors such as push buttons, accelerome-
ters, security seals, and motion sensors.
2.6 Sensor Interface
The sensor can interface to:
• Four switch sensors
• A motion sensor for use with external ball-in-tube
• A pulsed comparator
• A Sample Measurement Unit (SMU) ADC
• A current generator for measurement
The switch sensors, motion sensors, and pulsed com-
parator are available when the module is awake or
asleep. The SMU ADC is only available when the mod-
ule is awake. The sensor elements share the module’s
eight sensor pins.
When the module is asleep, the sensor interface can
be used to detect events such as a switch opening or
closing, motion, or an analog voltage moving outside of
a preset window. When the module is awake, the SMU
can digitize the analog signals and make high-precision
analog measurements.
2.7 General Purpose In put/Output
(GPIO) Pins
The RN171 has 14 GPIO (GPIO1 through GPIO14)
pins that can be commanded by ASCII commands.
GPIO10 through GPIO14 pins have secondary func-
tions for the UART (TX, RX, CTS, and RTS), while oth-
ers can control connection modes, LEDs, etc.
Refer to the “WiFly Command Reference, Advanced
Features and Applications User's Guide”
(DS50002230) for information on configuring and con-
trolling the module.
Note: Use hardware flow control for baud rates
of 115,200 and higher.
Note: The over-the-air FTP update image file
(*.img) is not compatible with the ISP.
WARNING
DO NOT apply voltages greater than 1.2V on any
of the sensor pins.
RN171
DS70005171B-page 10 2014-2016 Microchip Technology Inc.
2.8 Power Management
The module supports an ultra-low power sleep state,
from which it can wake for a range of detected reasons.
It transitions from asleep to CPU-active in 1.7 ms, and
CPU active to network connection in less than 35 ms
(typical). The RN171 also supports a keep-alive doze
state that provides an instant transition to a wake state.
2.8.1 FORCE AWAKE
The RN171 may be forced awake by asserting the
FORCE_AWAKE pin for at least 245 ms. If the
FORCE_AWAKE pin remains asserted, the module is
prevented from sleeping or dozing.
2.8.2 POWER SUPPLY
For supply voltages in the range of 3.0 to 3.7 volts, con-
nect the module using the power supply (no boost cir-
cuit). Refer to Figure 3-1 for an example.
2.8.3 BATTERY BOOST CONTROL
CIRCUIT
The RN171 includes a battery boost control circuitry for
battery voltages in the range of 1.8 to 3.3V. Five exter-
nal components as shown in Figure 3-2 make up the
battery boost circuit.
2.9 Module Reset
There are several ways to Reset the module:
• A Power-On Reset is generated automatically
when power is applied. This Reset is intended to
initialize the module when a new battery is con-
nected.
• Perform an external Power-On Reset by pulling
the RESET pin low.
• Perform a soft Power-On Reset using software
commands.
• A Reset can be triggered by a critical event, such
as a brownout, generated if the supply voltage
drops below the minimum operating voltage
2.9.1 BROWN-OUT DETECTION
The RN171 includes a brown-out detector that holds
the module in Reset if the battery voltage falls below
the minimum operating voltage.
WARNING
The battery boost circuit should not be operated with
battery supply voltages above 3.3 volts.
Note: If the RN171 module is used in battery
applications, it is highly recommended
that a voltage supervisory device be
employed.

FIGURE 3-3: IN-SYSTE M PROGRAMMING (ISP) HEADER
3.2 External Antenna Types
The RN171 module has a 50 antenna connection on
pin 24. Connect to an antenna through a host PCB
micro-strip trace layout to an external connector, PCB
trace antenna, or component (chip) antenna. This trace
can be extended to include passive parts for antenna
attenuation padding, impedance matching, or to pro-
vide test ports. Other components, such as amplifiers
and active drivers, are not considered part of the trace
layout and may void the RN171’s modular certification.
It is recommended that the trace layout from pin 24 to
the external connector or antenna be as short as pos-
sible for minimum loss and best impedance matching.
If the trace layout is longer, it should be a 50 imped-
ance microstrip or coplanar waveguide PCB trace.
Adjacent ground pins 21-23 and 25-27 should be con-
nected to a low-impedance ground plane on the host
PCB.
Modular certification of the RN171 module was per-
formed with the external antenna types listed in
Table 3-1. An antenna type comprises antennas having

• United States
• Canada
• Europe
• Australia
• New Zealand
•Korea
• Other Regulatory Jurisdictions
4.1 United States
The RN171 module has received Federal Communica-
tions Commission (FCC) CFR47 Telecommunications,
Part 15 Subpart C “Intentional Radiators” modular
approval in accordance with Part 15.212 Modular
Transmitter approval. Modular approval allows the end
user to integrate the RN171 module into a finished
product without obtaining subsequent and separate
FCC approvals for intentional radiation, provided no
changes or modifications are made to the module cir-
cuitry. Changes or modifications could void the user’s
authority to operate the equipment. The end user must
comply with all of the instructions provided by the
Grantee, which indicate installation and/or operating
conditions necessary for compliance.
The finished product is required to comply with all appli-
cable FCC equipment authorizations regulations,
requirements and equipment functions not associated
with the transmitter module portion. For example, com-
pliance must be demonstrated to regulations for other
transmitter components within the host product; to
requirements for unintentional radiators (Part 15 Sub-
part B “Unintentional Radiators”), such as digital
devices, computer peripherals, radio receivers, etc.;
and to additional authorization requirements for the
non-transmitter functions on the transmitter module
(i.e., Verification, or Declaration of Conformity) (e.g.,
transmitter modules may also contain digital logic func-
tions) as appropriate.
4.1.1 LABELING AND USER
INFORMATION REQUIREMENTS
The RN171 module has been labeled with its own FCC
ID number, and if the FCC ID is not visible when the
module is installed inside another device, then the out-
side of the finished product into which the module is
installed must also display a label referring to the
enclosed module. This exterior label can use wording
as follows:

(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 equipment has been tested and found to com-
ply with the limits for a Class B digital device, pursu-
ant 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 or more of the fol-
lowing measures:
• Reorient or relocate the receiving antenna.

4.1.2 RF EXPOSURE
All transmitters regulated by FCC must comply with RF
exposure requirements. OET Bulletin 65, Evaluating
Compliance with FCC Guidelines for Human Exposure
to Radio Frequency Electromagnetic Fields, provides
assistance in determining whether proposed or existing
transmitting facilities, operations or devices comply
with limits for human exposure to Radio Frequency
(RF) fields adopted by the Federal Communications
Commission (FCC). The bulletin offers guidelines and
suggestions for evaluating compliance.
If appropriate, compliance with exposure guidelines for
mobile and unlicensed devices can be accomplished
by the use of warning labels and by providing users
with information concerning minimum separation dis-
tances from transmitting structures and proper installa-
tion of antennas.
The following statement must be included as a CAU-
TION statement in manuals and OEM products to alert
users of FCC RF exposure compliance:
If the RN171 module is used in a portable application
(i.e., the antenna is less than 20 cm from persons
during operation), the integrator is responsible for per-
forming Specific Absorption Rate (SAR) testing in
accordance with FCC rules 2.1091.
4.1.3 APPROVED EXTERNAL ANTENNA
TYPES
To maintain modular approval in the United States,
only the antenna types that have been tested shall be
used. It is permissible to use different antenna manu-
facturers provided the same antenna type that has sim-
ilar in-band and out-of-band radiation patterns and
antenna gain (equal to or less than) is used.

Note the following details of the code protection feature on Microchip devices:
• Microchip products meet the specification contained in their particular Microchip Data Sheet.
• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
• Microchip is willing to work with the customer who is concerned about the integrity of their code.
• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
