RM-UPLYNX-E003 version 1.0 Confidential and Proprietary 10 3 Functional Description The core of the Uplynx-M-RCZ24 module is the Uplynx M2C8001 SOC. The module design is based on the M2C8001 Sigfox VerifiedTM reference design. The Uplynx-M-RCZ24 has 6 sets of analogue/digital multi-function pins and digital only multi-function pins. Each multi-function pin can be configured by the user. The Uplynx-M-RCZ24 communicates with the host MCU over a UART interface. The preloaded UART interface firmware is configured at 9600bps baud rate, 8-bit data, no parity bit, 1 stop bit and no flow control. The STATUS pin indicates the activity of the Sigfox AT command interface. The module is switched ON and OFF with the POW_EN pin. In OFF mode, the module current consumption can be cut to its minimum (0.05µA) for longer battery operating time, an essential requirement for Sigfox where modem activity is very low. The RF output is a 50Ω IPEX connector and the whole module is shielded for best spurious containment.

To enter the firmware update mode, user can I. Pull pin 16 low at startup (i.e. the STATUS pin of module) On start up, the bootloader polls the module “STATUS” pin which is pin 16 of the SOC. If the pin is logically low, the UART on the SOC is configured as 115200bps and the bootloader is waiting for firmware via XMODEM. User can then upload the application binary file to the SOC via XMODEM. Details can be found in “RM-UPLYNX-E001: Uplynx AT Command GUI and EasyAT User Guide”. The application will be stored at the application startup address and be uploaded after the system is rebooted. Details can be found in the “Uplynx Software Development Kit User Guide”. Since the “STATUS” pin is an output pin at normal operation, it is important to ensure the pin is NOT pulled down by the application circuit during normal startup. II. Enter AT$FW=1 when the Sigfox verified AT command interface is uploaded, the module enters XMODEM mode after the AT$FW command is asserted. The speed of UART is
RM-UPLYNX-E003 version 1.0 Confidential and Proprietary 19 configurable to 115200bps. The new firmware is to be transmitted via XMODEM protocol over UART and will be installed automatically. Upon successful update, the new firmware will be uploaded on the next reboot. Details can be found in “RM-UPLYNX-E001: Uplynx AT Command GUI and EasyAT User Guide” 6.4 Device ID, KEY and Portable access code As part of the Sigfox operation requirements, each Sigfox device must be assigned a unique identification number (ID), encryption key (KEY) and portable access code (PAC). This information is preloaded in the module and only the ID and PAC can be read via AT command. 7 Transmission Power and Current Consumption 7.1 Transmission Power vs. Input Voltage 902.2MHz VDD Power Current (Continuous Wave) 5 22.3 170.6 4.5 22.3 170.6 4 22.3 170.6 3.9 22.3 170.6 3.8 22.3 170.6 3.7 22.3 170.6 3.6 22.3 170.6 3.5 22.3 170.6 3.4 22.3 170.6 3.3 22.16 167.5 3.2 21.96 163.4 3.1 21.75 159.6 3 21.53 155.9 2.9 20.31 152.5 2.8 21.06 149.3 2.7 20.8 146.1 2.6 20.5 142 2.5 20.1 135.8 Table 7-1 Recommended Pin Connections The current consumption of the Uplynx-M-RCZ24 is measured and data is presented as a reference.

RM-UPLYNX-E003 version 1.0 Confidential and Proprietary 21 8 Application Information 8.1 Mounting Considerations Please note this module is designed for inclusion in an embedded design. If you need an off-the-shelf solution you can purchase one of the Uplynx-M-RCZx Evaluation boards. Surface mount board layout is a critical portion of the total design. The footprint for the module must be the correct size to ensure proper solder connection interface between the board and the module. With the correct pad geometry, the module will self align when subjected to a solder reflow process. User should surface mount the module onto their hosting PCB with all pads soldered properly. All the control signal and ground pads must be connected properly to ensure correct operation. 8.2 Recommended connection to essential pins PIN Recommendation TX_OUT The 50Ω RF output should be connected to a pi/T antenna matching circuit for potential antenna tuning. An ESD diode could be placed at the antenna port to protect the product against an ESD event induced due to human activity. VSS The RF performance relies strongly on a good quality ground. It is recommended to use a ground plane if possible or thick and close ground traces are required to minimize radiation and ensure the best RF performance STATUS Can be connected to the host processor to detect module status or the pin can lead to a status LED for displaying purposes VDD The voltage supply can come directly from a cell, ac adapter or USB. A decoupling capacitor of size 10µF placed close to the 5V input is recommended. The allowable voltage at this power input is below 5.5V and above 2.6V. POW_EN It is connected to a host processor to switch on and off the modem module. RST_N This can be tied to a universal reset pin or the host processor. It is internally pulled high to VLDO. In other words, RST_N only works when POW_EN is set high. A 10µF capacitor would be recommended in place close to the module pin in case the supply voltage to the module. The pull high resistance onto pin RESET_N from the system must be smaller than 50k Ω to ensure proper module startup. VLDO This is the output of the internal LDO of the module. This voltage supply is used by the module RF system and it is highly recommended to leave this pin unconnected. In case this supply is used by another part of the system, a 1µF capacitor is recommended to be put close to the module. Table 8-1 Recommended Pin Connections
RM-UPLYNX-E003 version 1.0 Confidential and Proprietary 22 Figure 8-1 Typical Application Circuit 8.3 Switch ON and OFF procedure To ensure proper operation, POW_EN must be asserted high after 5V has settled then wait for 5ms before AT commands can be passed down the UART interface. The settling time is required for the LDO and crystal oscillator to settle to their operating conditions. A software routine can be used to poll the status of STATUS pin before any actual payload is passed to the module. After switching the module OFF, by pulling POW_EN low, it is highly recommended that the system should wait for at least 10ms before another attempt to power ON. 8.4 RF power and current measurement. The Uplynx M2C8001 operates from 1.8V to 3.6V and the module is designed to leave enough headroom for battery voltage variation and also provide maximum RF transmission power. 3.6V is selected. With AT$302, the module transmission power is configured within the range of 14 to 22. The transmission power and current consumption are measured and are shown below. The user can select an appropriate power level setting to accommodate losses. 8.5 RF Grounding for FCC compliance The Uplynx-M-RCZ24 is designed to deliver ~22dBm and is compliant to FCC emission regulations. To achieve the tight emission limitation of the restricted bands, the grounding of the module must be maintained by connecting all the ground pads to a large ground plan in the PCB stack. It is highly recommended that the mother board be designed with dedicated ground plane which connect to all the VSS pins on the module. The VSS pads must be connected to the ground plane with a minimum of 3 vias. Decoupling capacitors must be located close to the module supply voltage. To maximize heat dissipation, the large ground pad must be connected
