Orca Systems has launched its first wireless system-on-chip (SoC) solution for the satellite Internet of Things (IoT), the ORC3990. The fully integrated SoC meets the demands of satellite IoT connectivity, providing enabling RF technology for direct-to-satellite, indoor operation over Totum’s Low Earth Orbit (LEO) network.

A Totum satellite technology-based terrestrial endpoint for a LEO network using the ORC3990 SoC requires a minimal bill of materials (BOM). External components are reduced to a temperature-compensated crystal oscillator (TCXO), passive filters and switches, a PCB antenna, and a battery. For simple, compact “tracker-on-a-chip” applications supporting global connectivity and positioning, a sub-$10 endpoint solution is possible based on the ORC3990 SoC.

The ORC3990 SoC integrates all required system functions into a single, cost-effective device in a very small 68-QFN package. An essential building block of the SoC design includes Orca Systems’ flexible, third-generation Live Wireless RF and digital radio subsystem, which has been customized to support the requirements of Totum’s LEO satellite network. Additional function blocks integrated within the ORC3390 SoC include a low-noise amplifier (LNA), a digital power amplifier (PA), the Totum satellite modem, a power-management unit (PMU) subsystem including all analog blocks, dual Arm Cortex-M0+ CPUs for separate network and application processing, all necessary memory (volatile and non-volatile) for the on-chip CPUs, required security functions, and key analog and digital peripherals.
