1Product Overview
The UPLYNX-M-RCZ24 is a Sigfox Verified modem module for the low power wide area network
(LPWAN) market. It is designed with M2COMM’s Uplynx M2C8001 SOC. The module was
designed for high performance, high quality, small form factor and a low cost. The design is fully
compliant with FCC part 15.209. The Sigfox application is ported over the Uplynx M2C8001 and
executed at high efficiency using its internal 32bit core processor. Every module is preloaded
with Sigfox application software and module specific ID/KEY/PAC as specified by the Sigfox
network system. The preloaded software also includes a bootloader which allows software
updates or future user application development.

3Functional 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 50ΩIPEX connector and the whole module is shielded for best spurious
containment.

6.2 Special Notes for Sigfox AT command interface
To load the Sigfox library for specific region X, one should set (AT$RCZ) and confirm
(AT$RCZ?) the value stored for RCZ then execute AT$O=1,X
The configuration set by the following AT commands will be stored on flash and the
value will be retained even after power off
oTransmitting frequency (i.e. AT$IF)
oTransmitting power (i.e. AT$302)
oSigfox configuration word (i.e. AT$400)
oThe following setting must be loaded to ensure normal Sigfox network activity:
RCZ2: AT$IF=902200000, AT$400=1,0,0,1

oSet RCZ region by AT$RCZ
6.3 Bootloader
The preloaded bootloader allows the user to reprogram the flash in the SOC. 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.

The current consumption of the Uplynx-M-RCZ24 is measured and data is presented as a
reference. The current is measured using the evaluation kit for Uplynx-M-RCZ24. Current
through J2 is measured by a Tektronix MDO3104 and a TCPA300. The module is configured for
