nRF52840-QIAA-R
Overview
The nRF52840-QIAA-R is a high-performance multiprotocol SoC featuring an Arm Cortex-M4 with FPU running at 64MHz and an integrated 2.4GHz radio. It supports Bluetooth 5.0, Thread, and Zigbee, while providing 1MB of Flash and 256kB of RAM for complex application code and networking stacks. The device is particularly notable for its hardware-based security features, including the Arm TrustZone CryptoCell-310 subsystem.
Why Choose This Part
This SoC offers a significant memory headroom of 1MB Flash and 256kB RAM, which is essential for running concurrent protocols like Bluetooth and Thread. Its comprehensive security suite, including RSA-2048 and ECC support, provides a robust root-of-trust for connected devices. Additionally, the integrated USB controller and on-chip balun simplify PCB design and reduce total bill-of-materials cost.
