nRF52805 Wireless SoC by Nordic Semiconductor
The nRF52805 from Nordic Semiconductor is a Bluetooth 5.2 System-on-Chip (SoC) which is designed for small two-layer PCB designs. This SoC has been developed for cost-constrained applications and is the perfect choice for applications such as beacons, disposable medical devices, sensors, styluses, and presenters.
The 2.4 GHz multiprotocol radio provides up to 4 dBm of output power and has a receiver sensitivity of -97 dBm. It supports all Bluetooth Low Energy features, including Direction Finding, the throughput of 2 Mbps, Long Range operation, and all Bluetooth 5.2 features. The device requires a supply of 3 VDC and draws only 4.6 mA in both Tx (0 dBm) and Rx modes.
The nRF52805 is based on a 64-MHz Arm Cortex-M4 processor. It has 192 KB Flash memory and 24 KB RAM, and a range of analog and digital interfaces such as 12-bit ADC, UART, SPI, and TWI. It is available in a WLCSP28 package with 10 GPIOs that measure 2.48 x 2.46 mm.
