Nordic nRF52805 – Bluetooth 5.2 SoC in a WLCSP optimized for small two-layer PCB designs

nRF52805 is an ultra-low power Bluetooth® 5.2 System on Chip (SoC) supporting Bluetooth Low Energy and 2.4 GHz proprietary protocols.

The nRF52805 supports Bluetooth high-throughput 2Mbps, transferring data faster and more efficiently, and Bluetooth channel selection algorithm #2 (CSA #2), improving coexistence and reducing interference. The radio has up to 4dBm TX power and -97dBm sensitivity (1Mbps Bluetooth Low Energy).

The nRF52805 device compliments the extensive nRF52 Series platform with an SoC in a WLCSP optimized for small two-layer PCB designs, significantly decreasing cost compared to four-layer PCBs. A 9.5 x 8.8mm reference layout with all ten GPIOs available is provided, requiring only 10 external passive components (including two crystal load capacitors). nRF52805 features a 64MHz Arm® Cortex®-M4 processor with 192kB of flash memory and 24kB of RAM. A wide range of analog and digital interfaces is integrated, including a 2-channel 12-bit ADC, SPI, UART, and TWI. It is the perfect choice for applications such as beacons, disposable medical devices, sensors, styluses, and presenters.
