It augments the already exten- 256 KB Flash + 32 KB RAM sive collection of wireless SoCs with a lower-end option with Bluetooth Low Energy built-in USB and a fully-featured multiprotocol radio. The nRF52 Series is truly the ideal platform for basing a product portfolio y Bluetooth 5.2 upon. The common hardware and software architecture results y Direction Finding in excellent software portability, increasing software reusability y High-throughput 2 Mbps and lowering time-to-market and development cost. y Long Range Bluetooth mesh 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 Thread and Zigbee (802.15.4) analog and digital interfaces such as an analog comparator, SPI, Ultra-low-power 2.4 GHz multiprotocol radio UART, TWI, QDEC, and last but not least, USB. It can be supplied y +8 dBm TX power with a voltage from 1.7 to 5.5 V which enables powering the de- y -95 dBm RX sensitivity vice from sources such as rechargeable batteries or via USB. y 4.9 mA in TX (0 dBm) The nRF52820 supports Bluetooth Low Energy, and is capable y 4.7 mA in RX (1 Mbps) of all Bluetooth 5.2 features, in addition to the Direction Find- y Integrated balun with single-ended output ing, high-throughput 2 Mbps and Long Range features. It also 12 Mbps Full Speed USB 2.0 capable of Bluetooth mesh, Thread and Zigbee mesh protocols. Integrated DC/DC regulator Extended temperature range: -40C to +105C For HID applications the built-in USB and +8 dBm TX power make the nRF52820 a great single-chip option, while asset 1.7-5.5 V supply voltage range tracking applications can leverage its Bluetooth Direction Find- ing capabilities. The extended temperature range of -40 to +105 C makes it suitable for professional lighting applications. APPLICATIONS Advanced beacons The built-in USB, fully-featured multiprotocol radio and +8 HID dBm output power makes it the perfect network processor to be paired with an application MCU in gateways and other Bluetooth LE USB dongle smart home, commercial and industrial applications requiring Bluetooth LE mouse advanced wireless connectivity.
