nRFnRF52833-CJAA-R
Overview
The nRF52833-CJAA-R is a versatile multiprotocol SoC featuring a 64 MHz Arm Cortex-M4 with FPU, 512 KB Flash, and 128 KB RAM. It supports Bluetooth 5.1 Direction Finding, Bluetooth Mesh, Thread, Zigbee, and 802.15.4, making it a robust solution for advanced wireless connectivity in a compact form factor. Integrated features like a full-speed USB 2.0 interface and an NFC-A tag simplify hardware design for professional-grade peripherals.
Why Choose This Part
The SoC offers an extensive 1.7V to 5.5V supply range with an integrated DC-DC regulator, allowing for direct operation from USB power or Li-ion batteries. Its 128 KB RAM is significantly larger than previous generation mid-range SoCs, enabling more complex software stacks and larger application buffers. Additionally, the integrated balun reduces the external component count and PCB footprint compared to discrete RF designs.
Applications
Getting Started
Development is centered around the nRF5 SDK or the newer nRF Connect SDK based on the Zephyr RTOS. Engineers should use the nRF52833-DK development kit for initial prototyping and the nRF Connect for Desktop software suite for RF testing and power profiling. Programming and debugging are typically handled via a standard SWD interface using a SEGGER J-Link probe.
Dev Boards
Development boards and breakout modules featuring the nRF52833-CJAA-R or compatible chips — ready to use for prototyping.
