Applications
The nRF52820 System-on-Chip (SoC) is the 6th addition to the industry-lead - ing 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. nRF52805 nRF52810 nRF52811 nRF52820 nRF52832 nRF52833 nRF52840 nRF5340 Bluetooth 5.3 X X X X X X X X Bluetooth

Built-in USB for communication, DFU and power supply The nRF52820’s USB peripheral implements a Full Speed USB 2.0 device that offers a widely-used interface that enables low-latency and high-bandwidth communication with a range of hosts, such as PCs, tablets, smartphones, and gateways. It also adds the option of performing device firmware updates (DFU) over USB. When connected to a USB host, the nRF52820 can be directly powered by the always-present 5 V VBUS signal. Nordic provides a reference layout for this configuration. In addition to the main supply regulators, the USB peripheral in the nRF52820 integrates a dedicated regulator for converting the 5 V VBUS signal to the 3.3 V needed for supplying the USB signaling interface, removing the cost and space for an exter - nal regulator. nRF Connect SDK The nRF Connect SDK is our software development kit for the nRF52820 SoC. It supports development of Bluetooth Low Energy, Thread and Zigbee applications. It integrates the Zephyr RTOS, protocol stacks, samples, hardware drivers and much more. Our nRF Connect SDK also supports the nRF9160, our LTE-M/NB-IoT/GPS SiP, and the nRF53 Series. It is a common platform for both cellular IoT and short-range development. nRF52833 DK The nRF52833 DK is the affordable development kit for the nRF52820 SoC. The nRF52833 has a superset of the nRF52820’s features. The DK has everything needed for develop ment on a single board. All features and GPIOs of the SoC are made available to the developer, and it comes with an on-board SEGGER J-Link debugger enabling both programming and debugging of the nRF52833. The kit is compatible with the Arduino Uno Rev3 standard, has access to all I/Os (42) and interfaces via connectors, and there is an integrated PCB trace antenna and an RF connector for direct RF test measurements. The nRF52820 SoC and the nRF52833 DK are available for purchase through our distribution network. 2×12C HS-SPI Debug
