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 com-

mand 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

used

monitor

analog

signals

such

temperature, audio, motion, and acceleration.

The module has a small form factor, which makes it

easy

integrate.

Additionally,

the

module

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 sen-

sor 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
