NRF52820-QDAA-R RF System on a Chip – SoC nRF52820-QDAA QFN 40L 5×5

The nRF52820 System-on-Chip (SoC) is the 6th addition to the industry-leading nRF52® Series. It augments the already extensive collection of wireless SoCs with a lower-end option with built-in USB and a fully-featured multipro-tocol radio. The nRF52 Series is truly the ideal platform for basing a product portfolio upon. The common hardware and software architecture results in excellent software portability, increasing software reusability and lowering time-to-market and development cost.

The nRF52820 features an Arm® Cortex®-M4 processor, clocked at 64 MHz. It has 256 KB Flash and 32 KB RAM, and a range of analog and digital inter-faces such as an analog comparator, SPI, UART, TWI, QDEC, and last but not least, USB. It can be supplied with a voltage from 1.7 to 5.5 V which enables powering the device from sources such as rechargeable batteries or via USB.

The nRF52820 supports Bluetooth 5.3, in addition to the Direction Finding, high-throughput 2 Mbps and Long Range features. It also capable of Blue-tooth mesh, Thread and Zigbee mesh protocols.

For human interface device (HID) applications the built-in USB and +8 dBm TX power make the nRF52820 a great single-chip option, while asset tracking applications can leverage its Bluetooth Direction Finding capabilities. The ex-tended temperature range of -40 to +105 °C makes it suitable for professional lighting applications.

The built-in USB, fully-featured multiprotocol radio and +8 dBm output power makes it the perfect network processor to be paired with an application MCU in gateways and other smart home, commercial and industrial applications requiring advanced wireless connectivity.
