NRF5340 in nRF53 Family
The nRF5340 is the world's first wireless System-on-Chip (SoC) featuring two Arm Cortex-M33 processors, engineered by Nordic Semiconductor. It serves as the flagship member of the nRF53 Series, designed to handle complex processing tasks and ultra-low-power wireless communication simultaneously. This high-end SoC supports Bluetooth 5.4, LE Audio, Bluetooth Mesh, Thread, and Zigbee, making it a premier choice for sophisticated IoT applications that require both computational power and robust multi-protocol connectivity.

Variants within the nRF5340 sub-family primarily differ by their packaging and intended hardware integration level. The QKAA-R and QKAA-R7 units are standard SoC chips in 94-pin VFQFN packages, differing only in tape-and-reel quantities. Developers can also find the CLAA variant which offers a smaller CSP footprint for space-constrained designs. Evaluation tools like the NRF5340-DK provide the full hardware environment, while the AUDIO-DK adds specific hardware for testing LE Audio capabilities.
