RN1723 1.0 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.

DS70005224A-page 7 RN1723 1.4 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. DS70005224A-page 8 2015 Microchip Technology Inc. RN1723 2.0 2.1 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 38,400 115,200 230,400 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 – SENSOR_IF, 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. TABLE 2-1: ANALOG SENSOR INPUTS Parameter Value AD SENSOR_IF[0 – 7] measurement range 0-400 mV (not to exceed 1.2 VDC) Resolution 14 bits = 12 µV Accuracy 5% uncalibrated; 0.01% calibrated Minimum conversion time 35 µs (5 kHz over Wi-Fi®) For additional instructions on how to read and manage the data from the analog sensor inputs, please refer to the show q <value> command in the “WiFly Command Reference, Advanced Features and Applications User’s Guide” (DS50002230). DS70005224A-page 9 RN1723 2.6.1 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 and SENSOR_IF, respectively. When properly enabled, any transition activity on either sensor will wake up the RN1723. SENSOR INPUT ENABLE Wake On Sensor Input Value 0 1 Set sys trigger 1 1 2 Set sys trigger 2 2 4 Set sys trigger 4 3 8 Set sys trigger 8 Command WARNING The voltage on any sensor input CANNOT exceed 1.2V DC. Failure to heed this warning could result in permanent damage to the module.

DS70005224A-page 11 RN1723 2.7 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. FIGURE 2-3: POWER SUPPLY FOR BATTERY (3.0V TO 3.7V) VBATT (49) RN1723 Battery 3.0V to 3.7V VDD (10, 34) SREG_3V3_CTRL (48) DS70005224A-page 12 2015 Microchip Technology Inc. RN1723 2.9.3 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.

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. DS70005224A-page 14 2015 Microchip Technology Inc. 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.
