RN1810/RN1810E
1.0 DEVICE OVERVIEW
The RN1810 and RN1810E are low-power, 2.4 GHz,
IEEE 802.11n compliant, surface mount modules
containing all associated RF components: crystal
oscillator, bypass and bias passives with integrated
MAC, baseband, RF and power amplifier and built-in
hardware support for encryption. Refer to Figure 1-1.
The integrated module design frees the designer from
RF and antenna design tasks and regulatory compli-
ance testing, ultimately providing faster time to market.
RN1810 incorporates an on-board TCP/IP networking
stack, cryptographic accelerator, power management
subsystem, real-time clock, 2.4 GHz transceiver and
RF power amplifier. With the module, designers can
embed Wi-Fi and networking functionality rapidly into
virtually any device.
The RN1810 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 RN1810 is configured with a simple ASCII com-
mand language.
In the simplest configuration, the module requires only
power, ground and UART TX and RX connections. The
RN1810 module can interface to low-cost microcontrol-
lers using only two wires, UART TX and RX.
The RN1810 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 WAKEUP signal.
Applications that make efficient use of the Sleep state
can extend battery life to multiple years.
The RN1810 module is approved for use with the inte-
grated PCB trace antenna. The RN1810E module is
approved for use with specific external antenna types
that are certified with the module. An ultra-small coaxial
connector (W.FL) is provided on the module for con-
nection to the external antenna. Refer to Section 3.3,
"External Antenna Types" for a listing of approved
antenna types.
The RN1810/RN1810E modules received the
regulatory approvals for modular devices in the United
States (FCC) and Canada (IC). Modular approval
removes the need for expensive RF and antenna
design, and enables the end user to place the RN1810/
RN1810E modules inside a finished product without
requiring a regulatory testing for an intentional radiator
(RF transmitter).
The RN1810/RN1810E module is an R&TTE Directive
assessed radio module for operation in Europe. The
module tests can be applied toward final product
certification and Declaration of Conformity (DoC).
Table 1-1 lists the RN1810 module's family types.
