Tiny cellular module provides worldwide connectivity for IoT edge devices

New Type 1SE module from Murata includes high-performance ST microcontroller and a hardware security framework.

Murata has introduced a new space-saving cellular networking module for LTE Cat.M1 and NB-IoT connectivity which provides a complete application-ready platform for IoT and smart connected devices.

 The LBAD0ZZ1SE is a Type 1SE module which integrates a microcontroller, the STMicroelectronics STM32L462, based on an Arm® Cortex®-M4 core, with a radio unit which operates in LTE bands and supports both the LTE Cat.M1 and NB-IoT Release 13 cellular communications protocols. The tiny module has a metal case and an LGA footprint for surface-mounting. Its dimensions are 15.4 mm x 18.0 mm x 2.5 mm. 

The LBAD0ZZ1SE is supplied with GCF and PTCRB carrier approvals and supports the Truphone eSIM technology to enable worldwide connectivity. A u.FL receptacle provides a connection to an external antenna. 

The module’s low power consumption gives up to 10 years of battery life. Hibernation current is 3 µA, and current in eDRX mode is <50 µA at eight hyperframes. 

The LBAD0ZZ1SE provides strong security capabilities to protect it from cyber-attack, including a secure boot architecture and a robust hardware-based security framework. Provision for over-the-air firmware updates ensures that security protection can be continuously maintained. Access to ST’s X-CUBE-CELLULAR software helps designers to accelerate system development.
