Single Chip LTE Cat M1/NB1 SoC with
embedded processor for the Internet of Things

Monarch SX is a highly-integrated single-chip LTE-M (Cat M1) and NB-IoT (Cat NB1) system-on-chip (SoC) with an embedded processor designed specifically for small form-factor, narrowband IoT applications, including trackers, sensors, wearables, and other low data-use, low power M2M and IoT devices. Monarch SX integrates Sequans’ Monarch, the world’s first and most highly optimized LTE-M and NB-IoT platform, and first to be certified by a tier-one operator, with an ARM® Cortex®-M4 processor, voice and audio engines with support for VoLTE on LTE-M, an always-on, ultra-low power sensor hub, and an advanced display controller to support a graphical user interface with touch screen functions. The Monarch SX modem complies with the ultra-low-power and reduced complexity feature requirements of the 3GPP release 13 LTE Advanced Pro standard, defining narrowband, low data rate LTE technology for machine-type-communications (MTC). Monarch SX achieves a very high level of integration whereby the ARM Cortex-M4 processor, dedicated media processing unit, sensor hub, baseband processor, RF transceiver, power management unit, and RAM are integrated into a tiny package, meeting the footprint requirements for the very smallest of IoT devices. Monarch SX runs Sequans’ SDK with a carrier-proven LTE protocol stack, an OMA lightweight M2M (LWM2M) client for over-the-air device management, a media engine, a sensor hub engine, and a royalty free RTOS.

Applications

Monarch SX is ideal for adding LTE Cat M1 and/or LTE Cat NB1 connectivity to narrowband, low data rate M2M and IoT devices, including asset trackers, wearables, smart utility meters, smart city and smart home sensors and a wide variety of additional industrial and consumer IoT applications.
