LNQNSM01 Pin Diagram 8. Typical Connection 8.1. Serial Connection to Host Processor The LNQNSM01 has a UART serial peripheral interface dedicated to communication with the module via a host controller or processor. Default UART specifications are provided in the table below and complete command interface documentation can be found in the LNQNSM01 Module Command Interface Reference Manual (DOCUMENT NUMBER HERE). 8.1.1. Default UART Interface Settings Parameter Setting Baud Rate Data Bits Parity Bit Stop Bit Flow Control 115200 8 1 None None 8.2. Interrupt Pins Four mappable interrupt pins are available based on application specific requirements. The available modes are detailed in the following table. 8.2.1. Interrupt Functions Signal Read data available Transmit queue empty Service queue empty Transmit active Receive active Network in sync Transmit buffer full Interference detected Service ACK received Service ACK time-out High priority alert Receive Ready 8.3. Antenna Pin Type Output Output Output Output Output Output Output Output Output Output Output Output Pin 18 on the LNQNSM01 connects to a 915 MHz antenna. It is matched to 50 Ohms. To maximize performance, it is important to make sure that any traces from the pin are matched to 50 Ohms. Antenna model:LNQNSM01 Antenna type:PCB Antenna gain:0dBi Manufacturer:LYNQ Technologies, Inc. 8.4. nReset Pin The nReset pin is an active-low input that resets the LNQNSM01 module MCU. It is recommended to connect a weak pull-up resistor to this pin. To prevent potential framing issues at power on, nReset should be asserted after the host controller has been powered on and initialized. 8.5. Time Synchronization Pin The time synchronization pin allows for a global clock to be used to synchronize the network rather than relying on relying on synchronization packets to maintain a network connection. This can be particularly useful when connected radios have a high probability of going out of range from one another for extended periods of time. In these instances units can become desynchronized and require some time to resynchronize with a network when back in range. Setting global times obviates the need for devices to resynchronize and allow devices to be perpetually synchronized regardless of time in isolation. The process for utilizing the global clock is generally as follows. 1. A one second timepulse, usually from a device with a global clock source such as a GNSS receiver, is provided to the T_SYNC pin (see figure 8.5.1). This will force the LNQNSM01 to keep time using this clock source. Time is synchronized on the rising edge of the pulse. 2. Host processor sends a Synchronize Time command via UART to the network processor.

(see LNQNSM01 Module Command Interface Reference Manual for command information). Synchronization commands should be resent if the T_SYNC pin is every unapplied or if there is a system reboot. 8.5.1. Time Synchronization Pin Diagran 8.6. Enable Pin The enable pin is an input pin serves as a means of deep sleeping module components. It is intended to minimize the current draw to the device to act as an effective off switch for the module. When high, device operation is normal and all aspects of the system can be controlled. When the pin is pulled low, all on board components are disabled and the module cannot be communicated with. 8.7. SWD Pins See current draw characteristics in section 6, Operating Characteristics, for information on expected power consumption. SWD pins can be used for reprogramming the onboard microcontroller. It is highly recommended that all device firmware updates are issued using Lynqs UART bootloader and official Lynq support software only. 8.8. Power Supply Pins The LNQNSM01 power supply pins must be provided with a power source that allows for operation under the operating conditions defined by the users application. Refer to 6, Operating Conditions, for more information. It is recommended that additional capacitance is provided closely to each pin. Vdd and Vfem should be provided with a minimum of 4.7uF each. 8.9. Clock Output Pin The 8MHz source clock of the LNQNSM01 can be provided to other devices via the clock output pin. The use of this pin can be useful in saving in design cost or to provide a fully synchronized clock source with the LNQNSM01 module. 9. Regulatory Compliance 9.1. Countries of operation The LNQNSM01 has been approved for operation in the United States and Canada. Implementation of this product must follow the guidelines in this section under each respective country for the allowance of permissive operation. 9.2.
