Semtech announced the release of its LoRa Core portfolio with a new chipset.

According to the company, the portfolio provides LoRaWAN network coverage and targets several vertical industries.

It is compiled of sub-GHz transceiver chips, gateway chips, and reference designs including SX126x series, SX127x series, and LLCC68 transceiver chips. This is complimented by the SX130x series gateway chips, legacy gateway reference designs and the LoRa Corecell gateway reference designs.

Features of the SX1303, per a company press release, include the following:

  • Provides accurate time of arrival information for each demodulated LoRa frame

  • Fine timestamp is a nano second 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 additions to the LoRa Core portfolio include a gateway baseband processor and an associated LoRa Corecell gateway reference design that supports the fine timestamp feature.

The LoRa Corecell gateway reference design is available in the U.S., Europe, and some regions of China. It will help developers produce gateways integrating LoRa with optimal bill-of-material (BOM).
