Series Overview

Type ABZ is a new, compact, low cost, low power wide area network (LPWAN) wireless module that supports the LoRaWAN long range wireless protocol.
This new stand-alone module measures just 12.5 x 11.6 x 1.76 mm, is constructed in a metal shielded package and comprises a Semtech SX1276 ultra long range spread spectrum wireless transceiver and an STMicro STM32L0 series ARM Cortex-M0+ 32 bit microcontroller (MCU).
An integrated TCXO that has robust low drift thermal characteristics provides an accurate clock source for the RF transceiver.

The module is equipped with an ADC and up to 18 GPIO channels, allowing for flexible connections with sensors, switches, and status LEDs.
Murata’s CMWX1ZZABZ module has pre-certified radio regulatory approvals for use on the 868 MHz and 915 MHz industrial, scientific, and medical (ISM) bands in most geographical regions of the world.

The normal output power is +14 dBm but a PA boost function can be selected to increase RF output to +20dBm for long range applications or those where the end-device is sited in a poor signal location indoors.
The MCU includes 192 kB flash and 20 kB RAM, and has enough memory to embed customer applications and host other modulation stacks.
In addition, an optional STSAFE secure element can be incorporated into the MCU to enhance the network security capabilities.
Typical applications for this module include smart metering, wearables, tracking, M2M and internet of things (IoT) edge nodes.
Accommodating a wide range of temperatures, the module can operate from -40 to +85 °C.
