NRF5340-QKAA-R7

RF Transceiver ICS Overview

The nRF5340-QKAA-R7 is a dual-core Bluetooth System-on-Chip from Nordic Semiconductor, featuring two Arm Cortex-M33 processors. The Application Processor operates at up to 128 MHz with 1 MB Flash and 512 KB RAM, while the Network Processor runs at 64 MHz with 256 KB Flash and 64 KB RAM. It supports Bluetooth LE 5.4, LE Audio, Thread, Zigbee, and NFC. Key electrical parameters include a supply voltage range of 1.7 V to 5.5 V, maximum data rate of 2 Mbps, output power of 3 dBm, and sensitivity of -98 dBm. The device operates between -40°C and +105°C in a QFN-94 package.

RF Transceiver ICS Feature Summary

• Dual-core architecture separating application processing from network protocol handling for optimized performance and power efficiency.
• Supports advanced wireless protocols including Bluetooth LE Audio, Direction Finding, Thread, and Zigbee alongside standard Bluetooth LE.
• Integrated hardware security features including Arm TrustZone, CryptoCell-312, and secure key storage capabilities.

RF Transceiver ICS Applications

• LE Audio devices such as TWS earbuds and headsets
• Professional lighting and smart home controllers
• Advanced wearable electronics requiring extended temperature ranges

RF Transceiver ICS Procurement Notes

Verify the specific suffix against official Nordic documentation to confirm package type and tape/reel specifications. Ensure compatibility with the nRF Connect SDK version required for your target firmware. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement orders.

RF Transceiver ICS Selection Notes

Select this component when an application requires simultaneous execution of complex user logic and multiple wireless protocols. The dual-core design allows the network processor to handle radio stacks independently, freeing the application core for intensive tasks. Consider the 105°C operating limit for industrial or automotive environments where standard consumer-grade chips may fail.

RF Transceiver ICS Part Context

This part belongs to the nRF53 Series, representing Nordic Semiconductor's first dual-core wireless SoC. It builds upon the nRF52 series by adding a dedicated network processor and higher memory capacity. The series is designed for complex IoT applications demanding high performance, extensive connectivity options, and robust security features within a compact form factor.

RF Transceiver ICS Replacement Considerations

nRF5340-DK serves as a development platform rather than a direct pin-compatible replacement. For functional equivalents within the same family, consult Nordic's product selector for variants with different package sizes or memory configurations that match your PCB layout constraints.
