IEEE 802.11n Wi-Fi Solution + MCU SoC



NRC6791 is an SoC, highly integrated IEEE 802.11n RF/Baseband/MAC solution operating in a single stream mode for low-power standalone, embedded stations, access points, and Internet of Things (IoT) applications. NRC6791 supports both mandatory and optional features of the IEEE 802.11n standard and its corresponding Wi-Fi Alliance certifications. It can also be used in a variety of configurations, including IEEE 802.11b only and IEEE 802.11b/g or IEEE 802.11b/g/n combinations.

NRC6791 offers a complete and self-contained Wi-Fi networking solution by harnessing the capacity to host applications or offload Wi-Fi networking functions from another application processor. NRC6791 is specially designed to achieve the lowest power consumption with a combination of several proprietary techniques for low-power mobile wearable electronics and IoT applications. NRC6791 also includes Wi-Fi Direct and Wi-Fi Aware peer-to-peer technologies, allowing a great range of IoT usage, providing convenient and simple wireless connectivity, and enabling people to do more with their wireless products.

The RF is a complete radio front-end, optimized for IEEE 802.11b/g/n SoC implementation based on industry-proven direct conversion transceiver architecture. This transceiver IP has a fully integrated power amplifier and a CMOS RF switch. RF IO ports are single-ended and a fractional-N synthesizer while the power amplifier and PMU are fully integrated for minimum BOM and PIN counts.
