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 compliance 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 command 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 microcontrollers using only two wires, UART TX and RX. 2017 Microchip Technology Inc. The RN1810 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 (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 integrated 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 connection 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).

Advance Information DS50002460B-page 13 RN1810/RN1810E 2.2 MODE0 and MODE1 Pins 2.4 The MODE pins must be tied to the voltage levels for normal operation of the module. Refer to Table 2-1. TABLE 2-1: MODE PIN OPERATION Pin Condition MODE1 Connect to GND UART0_RX/MODE0 Connect to VDD via 100 k pull-up resistor The MODE pins are sampled at power on and wakeup. Refer to Section 2.4, "Sleep and Wakeup". In the case of UART0_RX/MODE0 pin, a 100 k pull-up resistor is required, and the host MCU allows an activehigh signal during power on and wake-up to ensure that the module start-up in normal operation. Once the module is operational, the pin becomes the UART0_RX pin. 2.3 VDD and GND Pin The RN1810/RN1810E wireless module contains an integrated power management unit that generates all necessary voltages required by the internal circuitry. The module is powered from a single voltage source. Table 2-2 lists the recommended bypass capacitors. The capacitors must be closely placed to the module.

FIGURE 3-1: APPLICATION SCHEMATIC DS50002460B-page 15 2: Hardware flow control is recommended for all baud rates, especially for 57,600 or greater. 3: The default firmware bootup UART baud settings is 9,600 with hardware flow control disabled. RN1810/RN1810E Advance Information Note 1: Refer to Table 1-2: "PIN Descriptions". RN1810/RN1810E 3.2 Integral PCB Trace Antenna For the RN1810, the PCB antenna is fabricated on the top copper layer and covered in solder mask. The layers below the antenna do not have copper trace. It is recommended that the module is mounted on the edge of the host PCB. It is permitted for PCB material to be below the antenna structure of the module as long as no copper traces or planes are on the host PCB in that area. For best performance, place the module on the host PCB according to the details shown in Figure 1-7. The antenna patterns plotted in Figure 3-2 through Figure 3-5 are the simulated results of the PCB antenna. FIGURE 3-2: DS50002460B-page 16 Figure 3-2 illustrates the simulation drawing. The twodimensional (2D) radiation pattern is illustrated in Figure 3-3, whereas Figure 3-4 and Figure 3-5 show the three-dimensional (3D) radiation patterns. The calculated average of the radiated field is shown in Figure 3-3. The radiation pattern for the XZ plane is shown in red, whereas the YZ plane is shown in violet. The most powerful radiation occurs in the XZ plane as represented by the red pattern. Figure 3-4 shows the relative position of the 3D radiation "donut" with reference to the module orientation. This is a very useful guide for placement of the module to obtain the maximum range. Figure 3-5 shows the 3D radiation pattern with the colored distribution of the radiation magnitude. The values range from -9 dB to +0.3 dB. This is very useful in interpreting the 2D radiation pattern. PCB ANTENNA SIMULATION DRAWING Advance Information 2017 Microchip Technology Inc.
