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 9 mm x 9.65 mm 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. It is uniquely applicable to the design of feature phones due to its ability to support VoLTE, music playback, LCD screen, and activity tracking, all with low power consumption.
