Overview

As an optimized Wi-Fi solution for the internet of things (IoT) devices, NRC7292 is the industry’s first system on a chip (SoC) that is compliant with the IEEE 802.11ah standard. Operating in the Sub 1GHz license-exempt band, it offers a much greater range over 2.4GHz and 5GHz technologies. 1/2/4MHz channel widths with optional short guard interval (SGI) yield 150 Kbps to 15 Mbps PHY throughput which can support the low-rate sensors to the high-rate surveillance camera application. The protocol’s power-saving mechanisms like a longer sleep time greatly reduce power consumption and hence increase battery life.

The self-contained IEEE 802.11ah Wi-Fi networking capabilities with fully integrated radio transceiver of NRC7292 offers the ideal solution to add Wi-Fi connectivity to IoT products. It minimizes the PCB size, requires minimal external circuitries, and enables fast time-to-market.

The RF transceiver is a complete radio front-end optimized for Sub 1GHz band and it has fully integrated pre-power amplifiers as well as the capability to support various commercial external FEM devices. With the dual embedded ARM Cortex-M0 and Cortex-M3 processor, NRC7292 can be used either as a standalone device or a slave to a host processor via the serial peripheral interface (SPI) or universal asynchronous receiver transmitter (UART) interface. In addition, it can support both AP and STA roles.
