Smart-Home Chipset Extends Battery Life to Four Years



Redpine Signal’s new RS9116N-DBT chipset addresses the connectivity requirements of smart-home devices, such as smart locks, security cameras, home appliances, alarm systems, doorbells and robots. It also delivers the power efficiency and hardware-assisted ML functions needed for artificial-intelligence and machine-learning smart systems.

The chipset provides simultaneously available multi-protocol wireless connectivity, ultra-low power, high data performance, a high level of security and the ability to run edge intelligence.

Housed in an 8.8 × 8-mm BGA package, the chipset integrates an ARM Cortex M4 microcontroller, advanced hardware security and multiple wireless protocols. It contains Wi-Fi, BT, BLE, ZigBee and Thread protocol stacks, automated mesh formation and reconfiguration capability for whole house coverage.

While current SoCs provide approximately seven months of battery life in a smart-home setting, the RS9116N-DBT chipset delivers four years of battery life, which is verified by an independent Tolly Report. The chipset consumes less than 113 uA to maintain cloud connection over Wi-Fi, which is one-fifth to one-fifteenth that of other chipsets in the market, said Redpine.

Other features include its ability to stream data at up to 100 Mbits/s and compatibility with all generations of Wi-Fi up to Wi-Fi 6. The RS9116n-DBT is currently in volume production.
