RC-LLCC68-868 LORA SMART HOME MODULE LoRa Smart Home module (based on Semtech LLCC68) liofuontroHi LoRa Smart Home (LLCC68) is a sub-GHz LoRa® RF Transceiver for medium range indoor and indoor to outdoor wireless applications. SPI interface. Designed for long battery life with just 4.2 mA of active receive current consumption. The LLCC68 can transmit up to +22 dBm with highly efficient integrated power amplifiers. These devices support LoRa modulation for LPWAN use cases and (G)FSK modulation for legacy use cases. The devices are highly configurable to meet different application requirements for consumer use. The device provides LoRa modulation compatible with Semtech transceivers used by the LoRaWAN® specification released by the LoRa Alliance®. The radio comprises four main blocks: 1.Analog Front End: the transmit and receive chains, as well as the data converter interface to ensuing digital blocks. The LR68NAC transceiver is capable of delivering up to +21 dBm under the battery supply. 2.Digital Modem Bank: a range of modulation options is available in the LR68NAC: 3.Digital Interface and Control: this comprises all payload data and protocol processing as well as access to configuration of the radio via the SPI interface. 4.Power Distribution: two forms of voltage regulation, DCDC or linear regulator LDO, are available depending upon the design priorities of the application. • Smart Home. • Smart Community. • Smart Meter. • Home and Building Automation Features LoRa and FSK Modem. 151 dB maximum link budget.
