California-based Semtech has released a LoRa smart home device for IoT applications. The radio frequency transceiver IC provides broad coverage, low power and low cost for applications in proximity of homes and buildings.
 
The device is for LPWAN-based smart home, community and consumer applications. The transceiver provides low power, broad coverage for indoor and neighbourhood area IoT devices connecting to sensors and actuators for safety, environmental and convenience use cases.
 
“With its simple and flexible network architecture, Semtech’s new LoRa smart home device offers a unique opportunity to accelerate the consumer adoption of smart home connections,” said Pedro Pachuca, director of IoT wireless at Semtech.
 
He said whether used end-to-end or as a complement to wifi, LoRa smart home broadens smart home products by enabling connectivity for low cost and battery powered end points both indoors and outdoors.
 
“The new LoRa smart home device is flexible and cost effective for low latency smart home applications, including smart key locks and lighting, enabling low cost network extension and providing a bridge to the many LoRaWan-based B2B and B2C available in the IoT market today,” said Pachuca.
 
The transceiver is for battery-powered sensors with multi-year operation. It features 600nA of sleep current and 4.6mA of active receive current consumption. With support for LoRa modulation for low power LAN use cases and (G)FSK modulation for legacy use cases, this device is compatible with existing LoRaWan-based networks and supports proprietary protocols.
 
Continuous frequency coverage from 150 to 960MHz allows the support of all major sub-GHz ISM bands around the world.
 
Features of the LLCC68 include: sensitivity to -126dBm; +22dBm output power with high efficiency PA; system works well even when the signal is 10dB below noise; low external BoM and matching; small foot print, 24-pin 4×4; works with existing LoRaWan-based gateways; less than 5mA RX current consumption; 25mA TX at +14dBm; integrated DC-DC and LDO; and it supports LoRaWan and other protocols.
