New LoRa Smart Home, Low Power RF Transceiver IC for Consumer IoT Devices

LLCC68 LoRa Transceiver Smart Home Device

Semtech Corporation has released a new LoRa Smart Home device (LLCC68) for medium-range indoor and indoor to outdoor wireless applications. This sub-GHz LoRa radio frequency transceiver provides broad coverage with low power and low cost, for applications in the proximity of homes and buildings.

 

The new transceiver features 600nA of sleep current and 4.6 mA of active receive current consumption and is intended for battery-powered sensors with the multi-year operation. The device supports LoRa modulation for low power LAN use cases and (G) FSK modulation for legacy use cases which makes it compatible with existing LoRaWAN-based networks and supports proprietary protocols. Its continuous frequency coverage (from 150 MHz to 960 MHz) allows the support of all major sub-GHz ISM bands around the world.

 

Features of LLCC68 LoRa Transceiver:

  • High sensitivity to -126 dBm
  • +22 dBm output power with high-efficiency PA
  • The system works well even when the signal is 10dB below noise
  • Minimal external BOM/matching
  • Small size footprint, 24-pin 4x4
  • Works with existing LoRaWAN-based gateways
  • <5 mA RX current consumption
  • 25 mA TX @ +14dBm
  • Integrated DC-DC and LDO
  • Supports LoRaWAN and other protocols

 

Note: More technical details can be obtained from the datasheet of LLCC68 Transceiver IC.

 

The device provides a flexible and cost-effective solution for low latency smart home applications including smart key locks and lighting. This offers a low-cost network extension and provides a bridge to the many LoRaWAN-based B2B and B2C solutions available in the IoT market.
