SX1303 LoRa Core Chipset from Semtech Corporation

SX1303 from Semtech Corporation is a new generation LoRa baseband processor that provides worldwide LoRaWAN network coverage and capabilities in several vertical industries including asset tracking, building, home, agriculture, metering, factory automation, and IoT applications. This new chipset enables the network-centric geolocation of LoRa devices without the inclusion of GPS hardware at each individual end node.

The device is based on a fine timestamp capability that provides an accurate time of arrival information for each demodulated message and allows gateways to perform network-centric geolocation based on Time Difference of Arrival (TDOA). This makes it ideal for several cost-sensitive asset tracking applications. The new SX1303 LoRa Core IC helps customers accelerate the development of their applications operating the LoRaWAN protocol.

Key Features of SX1303 LoRa Core Chipset

  • Provides accurate time of arrival information for each demodulated LoRa frame
  • Fine timestamp is a nanosecond resolution value references to a PPS (pulse per second) signal
  • Geolocation accuracy is around 75–150 meters depending on many different factors
  • Size and pin-to-pin compatible with LoRa Core SX1302
  • Featured for implementations leveraging the LoRaWAN protocol and worldwide sub-GHz bands
  • Up to -141dBm sensitivity with LoRa Core SX1250 Tx/Rx front-end
  • Unique 64-bit serialized number for identification and security purposes
  • Gateway offers lower power consumption and smaller size than legacy gateways

The new LoRa Corecell gateway reference design with a fine timestamp enables developers to produce gateways integrating LoRa with optimal bill-of-material (BOM) and the lowest power profile while offering the latest performance for network-centric geolocation. It is available in U.S., Europe, and China.
