NRF5340-QKAA-AB0-R7

RF Transceiver ICS Overview

The nRF5340-QKAA-AB0-R7 is a dual-core wireless System-on-Chip (SoC) from Nordic Semiconductor, designed for complex IoT applications. It integrates two Arm Cortex-M33 processors: an Application Processor with 1 MB Flash and 512 KB RAM running up to 128 MHz, and a Network Processor with 256 KB Flash and 64 KB RAM running at 64 MHz. The device features a 2.4 GHz transceiver supporting 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, transmit power of 3 dBm, and receive sensitivity of -98 dBm. Operating currents are 3.2 mA during transmission and 2.6 mA during reception. The component operates within a temperature range of -40°C to +105°C and utilizes a QFN-94 package.

RF Transceiver ICS Procurement Notes

Verify the specific suffix AB0 against official Nordic documentation to confirm exact pinout, antenna configuration, or pre-programmed firmware variations. Ensure compatibility with the nPM1100 PMIC for optimal power management in battery-operated designs. Confirm that the QFN-94 package dimensions align with your PCB footprint requirements before finalizing procurement orders.

RF Transceiver ICS Selection Notes

Select this SoC when both high computational performance and strict power efficiency are required simultaneously. The dual-core design allows the network processor to handle radio protocols independently, freeing the application processor for complex tasks. Choose this model over single-core alternatives if you require support for simultaneous mesh networking and application logic, or need extended temperature ratings for harsh environments.

RF Transceiver ICS Part Context

The nRF5340 series represents Nordic's first dual-core wireless SoC, bridging the gap between high-performance computing and ultra-low-power connectivity. It builds upon the nRF52 series capabilities by adding a dedicated network core and enhanced memory resources. This architecture enables sophisticated audio processing and concurrent protocol handling, positioning it as a central component for next-generation smart home and industrial IoT ecosystems.

RF Transceiver ICS Replacement Considerations

Direct substitutes within the same family include nRF5340-CLAA-R7 and nRF5340-QKAA-R. Verify package compatibility and pin assignments when swapping between variants. Cross-family replacements like the nRF52840 lack the dual-core architecture and may not support concurrent mesh operations or LE Audio features effectively.
