MAMWLExx is a new low power radio module with a high-performance processing unit for
the most complex task and high demanding applications.
The module comes with a great size of RAM and FLASH Memory which can be used for
important computing calculations and to embed the biggest software applications. It
even comes with a 64-bit unique identifier (DevEUI) in it, necessary to be compliant with
LoRaWAN standard. Since the module is based on STM SoC, it can be programmed using
ST environment itself, like STM32 CubeIde and STMCubeMX.
MAMWLExx module is designed to be easily integrated into any PCB offering two assembly
variants. One with a U.FL coaxial connector on the top of the package that can be directly
plugged into the antenna through a pigtail, saving space on the mainboard. The other
variants, that outputs the RF signal on a 50 Ohm pin,
fits you if you wish to create your own antenna design.
The module uses a high-performance ARM Cortex M4 32 Bits RISC core operating at 48
Mhz. The MAMWLExx has different types of low-power operation states, perfect for diffe-
rent applications especially the ones that need power saving.
MAMWLExx implements multiples radio modulations: LoRa, (G)FSK, (G)MSK, and BPSK with
different options (Bandwidth, SF, Powers, CR) to meet different needs of communication.
The module includes a 32MHz TCXO to drive the RF subsystem, and it is capable to output
up to +22dbm. MAMWLExx comes with a rich pin-out to meet different needs. Pin-out is
designed to use different peripherals at the same time using different protocols like I2C,
SPI, LPUART, USART. The module has 12 multiplexed pins for a 12 bit (up to 16 bits) SAR ADC
with DMA support, 12 bits DAC, 2 ultra-low-power comparator, multiple timers, and in-
dependent watchdog, JTAG and SWDIO debug capabilities. MAMWLExx has up to 32 I/O,
most of them 5V-tolerant. The module implements a hardware encryption/decryption
accelerator for different types of standards as AES (both 128 - 256 bits) and PKA for RSA,
Diffie-Hellmann, or ECC (Elliptic Curve Cryptography) over GF(p) (Galois fields).

The Sub-Ghz Radio is a low power radio with a high quality matching filter for operate in
the band of 868 Mhz and 915 Mhz. It can use different modulation techniques such as:
The radio is compliant for LoRaWAN specification and for different radio regulations ETSI
EN 300 220, EN 300 113, EN 301 166, FCC CFR 47 part 15, 24, 90, 101 and the ARIB STD-T30, T-67,
T-108.
The Sub-Ghz Radio is equipped with two high performance power amplifier to transmit
up to +22dBm and power can be programmed with a step of 1 dB within 32 steps. A high
quality TCXO 32 Mhz guarantees great stability during transmission.
LoRa modulation can operate with different bandwidth:
And with different Spreading Factors (from 5 to 12).
It can be set in multiple differents mode of operations for LoRa Packet (Explicit/Implicit
Header Mode) choosing also different coding rates:

The radio is completely programmable to achieve the best performances needs for dif-
ferent kind of application.
MAMWLExx comes with two different option:
1) 50 Ohm u.FL connector
2) 50 Ohm RF pin

7. HOW TO PROGRAM & DEBUG THE MAMWLEXX
HOW TO DEVELOP WITH MAMWLEXX
The MAMWLExx is compatible with all the software development environment that works
for the STM32 microcontroller series (e.g. STM32CubeIDE, Keil uVision, IAR Embedded).
The RF switch that selects the Tx/Rx path of the module is controlled by the STM32WL by
three GPIOs. Those GPIOs (PC3, PC4, PC5) aren’t output in the MAMWLExx footprint, but must
be driven in the firmware to use the RF part as desired (see tab). Same thing applies to pin
PB0 of the STM32WL that is connected (internally to the module) at the TCXO alimentation.
TCXO must be ON when using the RF part and can be OFF the rest of the time reducing the
overall consumption.
ThischoiceofcontrolpinsfortheRFswitchandtheTCXOisthesameasSTMicroelectronics.
In this way the user can run without further modification the code examples that comes
within the firmware packages released by ST for the STM32WL series.
Those example in the firmware packages are also the best way to start a new project with
the MAMWLExx.
HOW TO PROGRAM & DEBUG
There are many way to program and debug the MAMWLExx. The MAMWLExx comes with an
internal bootloader that support boot from SPI and USART, in addition the module can also
be programmed and debugged via the JTAG/SWD interface.
The best way to access those interfaces for programming is through the ST-LINK V3
debugger/programmer for STM32 micro series. The ST-link act like a bridge between the
board and the PC. It communicates with the PC via a microB-USB cable and has many
headers for connecting with various subsets of the SPI/USART/JTAG/SWD intefaces of the
module. If you would like to program using SPI or USART see AN2606 from ST first because
there are some details that you must pay attention of. For example if you would like to
RF front-end conguration PC4 PC5 PC3
TX high output power Low High High
TX low output power High High High
RX High Low High
Power -down Low Low Low
The u.FL connector is already applied on the top of the module with a high performance
Pi Filter, so there is no need to design any RF circuit to implement the module. To give the
best flexibility to the designer MAMWLExx implements a 50 Ohm pin antenna to enhance
a complete custom antenna design.
The module can implement Over-The-Air Firmware updates.
USING HEADER CN1 OF ST-LINK:
CN1 support the SWD/JTAG interface for programming and debugging the application
and provides a virtual com port (COM or VCP) that make simple printing string in a serial
terminal. To be able to connect the board to CN1, the board should have a twin header of
CN1 connected to the module like shown in the figure. While programming through CN1 is
not necessary to connect BOOT0 to VCC.
