DEVICE OVERVIEW
The RN1723 is a stand-alone, 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 RN1723, designers can embed
Wi-Fi and networking functionality rapidly into virtually
any device.
The RN1723 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 RN1723 is configured with a simple ASCII command language. The “WiFly Command Reference,
Advanced Features and Applications User's Guide”
(DS50002230), which is available for download from
www.microchip.com, contains a complete listing and
instructions of the ASCII command interface.
In the simplest configuration, the module requires only
power, ground, and UART Transmit (TX) and Receive
(RX) connections. The RN1723 module can interface
to low-cost microcontrollers using only two wires,
UART TX and RX.
The RN1723 has a versatile sensor interface that can
be used to monitor analog signals such as
temperature, audio, motion, and acceleration.
FIGURE 1-1:
The module has a small form factor, which makes it
easy to integrate. Additionally, the module is
compatible with standard pick-and-place equipment.
The RN1723 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 sensors.
The RN1723 can independently maintain a low-power
wireless network connection. Ultra-low power usage
and flexible power management maximize the
module’s lifetime in battery-operated devices. A wide
operating temperature range allows use in indoor and
outdoor environments (i.e., 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 sensor interfaces. Applications that make efficient use of
the Sleep state can extend battery life to multiple years.
The RN1723 has modular device approval for
operation in the United States (FCC) and Canada (IC).
The RN1723 module is an R&TTE Directive assessed
radio module for operation in Europe. Refer to
Section 4.0 “Regulatory Approval” for more
information.

Soldering Recommendations
The RN1723 wireless module was assembled using
the IPC/JEDEC J-STD-020 Standard lead-free reflow
profile. However, the RN1723 module can be soldered
to the host PCB using standard leaded and lead-free
solder reflow profiles.
To avoid damaging the module, it is recommended to
adhere to the following:
• Solder reflow recommendations are provided in
the Microchip application note, AN233 “Solder
Reflow Recommendation” (DS00233)
• Do not exceed a peak temperature (TP) of 250°C
• Refer to the vendor’s solder paste data sheet for
specific reflow profile recommendations
• Use no-clean flux solder paste
• Do not wash, as moisture can be trapped under
the shield
• Use only one flow. If the PCB requires multiple
flows, apply the module on the final flow.

CIRCUIT DESCRIPTION
(HARDWARE INTERFACE)
UART Interface
The UART interface supports 2-wire (RX and TX)
and 4-wire (RX, TX, CTS, and RTS) configurations
with hardware flow control. The logic levels are
CMOS voltage levels (not RS-232 voltage levels).
The UART interface supports the following baud
rates in bits per second:
•
•
•
•
•
•
•
2,400
4,800
9,600
19,200
38,400

230,400
Refer to the “WiFly Command Reference, Advanced
Features
and
Applications
User's
Guide”
(DS50002230) for UART configuration information.
Note:
2.2
The use of flow control is highly
recommended to ensure proper data
integrity.
SPI Master Interface
The RN1723 module contains a master Serial
Peripheral Interface (SPI), 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 Interface
The RN1723 modules contain an SDIO client with SDSPI 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 implemented in
the WiFly application.
2.4
In-System Programming (ISP)
The ISP_TX, ISP_RX, and other pins allow in-system
programming of the module. The RN1723 module
firmware can be upgraded by ISP using a *.bin file.
Note:
The over-the-air FTP update files (*.img
or *.mif) are not compatible with the ISP.
Optionally, it is recommended to place the ISP header
on the host PCB to facilitate firmware upgrades during
development and manufacturing. The header is two
rows by 8 pins with a 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 module for ISP.
The RN-ISP in-system programming interface connects to the module for ISP. In addition, refer to the RNISP product page on the Microchip web site for more
information.
 2015 Microchip Technology Inc.
2.5
The Sensor Interface
External sensor devices can connect to the RN1723
module via its sensor interface. There are a total of 8
sensor interface inputs available. They are labeled
SENSOR_IF[0] – SENSOR_IF[7], on the RN1723 Pin
diagram, as shown in Figure 1-2.
The sensor interface is suitable for, but not limited to,
connecting the following type of devices:
• Analog-to-Digital Conversion sensors
• Switch sensor
• Vibration sensors, motion sensors, and ball-and-tube
sensors
In addition to providing data input to the RN1723
module, some of the sensors can be used to wake-up
the module from sleep. A typical use case would have
one sensor input wake up the module, while another
sensor input provides it with external data that can be
transmitted wirelessly.
2.6
Analog Sensor Inputs
Eight sensor interface input pins, SENSOR_IF0
through SENSORIF7, can be used as analog sensor
inputs. The sensor pins are 1.2V tolerant and can
accept input voltages up to 1.2V, but saturate at
400 mV.
WARNING
DO NOT apply voltages greater than 1.2V on any
of the sensor pins. Failure to heed this warning
could result in permanent damage to the
module.
The RN1723 14-bit Analog-to-Digital Converter (ADC)
requires a 35 ms conversion time, with 0.01% linearity.
The pertinent analog sensor input specifications are
provided in Table 2-1.

SWITCH SENSORS
Please refer to the “WiFly Command Reference,
Advanced Features and Applications User’s Guide”
(DS50002230A), and the section on the set sys
trigger <mask> command for instructions on how
to enable the switch sensor inputs on the module.
Table 2-2 shows the specific value of the ‘mask’ that is
required to enable any of the SENSOR_IF[0 – 3] inputs
to act as module wake-up signals.
The RN1723 module has four switch sensor input pins
– SENSOR_IF[0 – 4]. These sensor pins can be used
to wake the module from sleep.
During sleep, the module can be configured to
continuously monitor the present state of the pins. Any
transition (low-to-high or high-to-low) will generate a
module wake-up signal.
TABLE 2-2:
A typical use case is to place the module into Sleep
mode, and use one of the switches to trigger a wake-up
event of the module. After waking up, the module can
then send a UDP/TCP packet.
Figure 2-1 shows an example schematic of how a
designer might connect both a simple Reed Switch and
tilt-vibe
motion
sensor
(SQ_SEN-200-C)
to
SENSOR_IF[0] and SENSOR_IF[3], respectively.
When properly enabled, any transition activity on either
sensor will wake up the RN1723.

General Purpose Input/Output
(GPIO) Pins
The RN1723 module has 14 GPIO (GPIO1 through
GPIO14) pins that can be commanded by ASCII commands. GPIO10 through GPIO14 pins have secondary
functions for the UART (TX, RX, CTS, and RTS), while
others 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
controlling the module.
2.8
Flash Voltage Supply
The FLASH_POWER pin on the RN1723 module is
used to power the internal Flash memory of the module. However, it can also supply other external components, up to a limit of 25 mA total current. When the
RN1723 is in Sleep mode, it does not drive this supply.
2.9
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 sleep to CPU active in 1.7 ms, and
from CPU active to network connection in less than 35
ms (typical). The RN1723 also supports a Doze state
that provides an instant transition from Sleep to a Wake
state.
2.9.1
FORCE AWAKE
The RN1723 module 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.
2.9.2
POWER SUPPLY
The RN1723 module is designed to operate with a wide
range of batteries, as well as a linear power supply.
A power source that supplies a constant voltage
greater than 3.0V can drive the module directly, as
shown in Figure 2-3.

BATTERY BOOST CONTROL
CIRCUIT
An external boost control circuit is required for battery
powered designs that provide less than 3.0V because
the RN1723 module does not have an internal boost
regulator circuit.
Figure 2-4 shows the recommended circuit for the
boost regulator.
WARNING
The battery boost circuit should not be operated
with battery supply voltages above 3.7 volts.
Failure to heed this warning could result in
permanent damage to the module.

Module Reset
There are several ways to Reset the module:
• A Power-on Reset (POR) is generated
automatically when power is applied. This Reset is
intended to initialize the module when a new
battery is connected
• Perform an external POR by pulling the RESET
pin low
• Perform a soft POR using software commands
• A Reset can be triggered by a critical event, such
as a brown-out, which is generated if the supply
voltage drops below the minimum operating
voltage
2.10.1
BROWN-OUT DETECTION
The RN1723 includes a brown-out detector that holds
the module in Reset if the battery voltage falls below
the minimum operating voltage.
Note:
If the RN1723 module is used in battery
applications, it is highly recommended
that a voltage supervisory device be
employed.

RN1723
The RN1723 module has a 50 antenna connection on
pin 24. Connect to an antenna through a host PCB
microstrip 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
provide test ports.
Note:
Other components, such as amplifiers and
active drivers, are not considered part of
the trace layout and may void the modular
certification of the RN1723 module.
It is recommended that the trace layout from pin 24 to
the external connector or antenna be as short as
possible for minimum loss and best impedance matching. If the trace layout is longer, it should be a 50
impedance microstrip or co-planar waveguide PCB
trace.
Adjacent ground pins 21-23 and 25-27 should be
connected to a low-impedance ground plane on the
host PCB.
Modular certification of the RN1723 module was performed with the external antenna types listed in
Table 3-1. An antenna type comprises of antennas having similar in-band and out-of-band radiation patterns.

New Zealand
The New Zealand radio regulations do not provide a
modular approval policy similar to the United States
(FCC) and Canada (IC). However, RN1723 module RF
transmitter test reports can be used in part to demonstrate compliance against the New Zealand “General
User Radio License for Short Range Devices”. New
Zealand Radio communications (Radio Standards)
Notice 2010 calls up the AS / NZS 4268:2008 industry
standard. The RN1723 module test reports can be
used as part of the product certification and compliance
folder. All test reports are available on the RN1723
product web page at http://www.microchip.com. For
more information on the RF transmitter test reports,
contact Microchip Technology sales office.

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.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.
