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).
