A Bluetooth 5 SoC for everybody
The nRF52805 System-on-Chip (SoC) is the 7th addition to the industry-leading nRF52® Series. It augments the already extensive collection of wireless SoCs with an SoC in a WLCSP optimized for small two-layer PCB designs, ideal for cost-constrained applications. It is the perfect choice for applications such as beacons, disposable medical devices, sensors, styluses and presenters. It can also be applied as a network processor, allowing another MCU to leverage its connectivity.
The nRF52 Series is truly the ideal platform for basing a product portfolio on; the common hardware and software architecture results in excellent software portability, increasing software reusability and lowering time-to-market and development cost.
The nRF52805 features an Arm® Cortex®-M4 processor, clocked at 64 MHz (144 CoreMark), with excellent efficiency (65 CoreMark/ mA). It has 192 KB Flash and 24 KB RAM and integrates a range of analog and digital interfaces such as a 2-channel 12-bit ADC, SPI, UART, and TWI. The SoC's current draw is as little as 0.3 µA in System OFF and 1.1 µA in System ON with 24 KB RAM retained and RTC running.
The nRF52805 is a Bluetooth 5.2 SoC supporting Bluetooth Low Energy and 2.4 GHz proprietary protocols. It is capable of Bluetooth high-throughput 2 Mbps, transferring data faster and more efficient, and Bluetooth channel selection algorithm #2 (CSA #2), improving coexistence and reducing interference. It also supports 2.4 GHz proprietary protocols. The radio has up to 4 dBm TX power and -97 dBm sensitivity (1 Mbps Bluetooth LE). The radio draws only 4.6 mA in both TX (0 dBm) and RX.
