Overview

The NRF5340-QKAA-R is a high-performance dual-core wireless SoC supporting Bluetooth 5.1, Thread, and Zigbee. It features an application processor and a network processor to isolate radio timing requirements from complex application code, making it a robust choice for multi-protocol 2.4GHz designs.

Why Choose This Part

The dual-core design significantly simplifies firmware development by preventing application code from interrupting time-critical radio tasks. It offers high sensitivity of -97.5dBm for reliable range and includes a full-speed USB interface for easy configuration and data transfer.

Applications

Advanced Wearables
Utilizes the dual-core architecture to handle high-resolution UI and sensor fusion on the application core while maintaining radio links on the network core.
Smart Home Hubs
Simultaneously supports Bluetooth LE and Thread or Zigbee mesh networking for interoperability between diverse home automation devices.
Professional Audio
Leverages the 2Mbps data rate and dedicated I2S interfaces for low-latency wireless audio streaming and control.
Industrial IoT Gateways
Integrates 1MB Flash and 256kB RAM to manage local data logging and cloud connectivity over encrypted wireless protocols.
