NRF52805 BLUETOOTH 5.2 SOC FEATURES A WLSCP, ENHANCED FOR SMALL TWO LAYER PCB MODELS

Nordic Semiconductor has announced the nRF52805, which is a microcontroller from the NRF52 series of microcontrollers. Measuring at just 2.48 x 2.46mm, the nRF52805 is the smallest of all the nRF52 series. Despite its small size, the nRF52805 System-on-Chip (SoC) top up the industry-leading Nrf52 Series with an SoC in a WLCSP enhanced for small two layer PCB designs, ideal for cost-constrained utility. The nRF52805 is the perfect alternative for applications such as beacons, disposable medical devices, sensors, styluses and presenters.

The nRF52805 features an Arm® Cortex® – M4 processor, clocked at 64 MHz, equipped with a 192 KB Flash and 24KB RAM, and incorporates wide variety of analog and digital interfaces such as a 2-channel 12 bit ADC, SPI, UART and TWI. The Nrf52805 which is a Bluetooth 5.2 SoC enables Bluetooth Low Energy and 2.4 GHz proprietary protocols. It enables Bluetooth high-throughput of 2 Mbps, transmitting info faster and even more efficient, and Bluetooth channel selection algorithm #2(CSA#2), improving coexistence ad reducing interference. The radio has up to 4 decibel-milliwatts TX power and -97 dBm sensitivity (1 Mbps Bluetooth LE).
