Nordic Semi’s new nRF52820, a new member in the nRF52 family

Nordic Semi has released the 6th multi-protocol SoC part of their nRF52 series with nRF52820 Bluetooth 5.2 ultra low force System-on-Chip (SoC) supporting Bluetooth Low Energy (Bluetooth LE), Bluetooth work, just as Thread, Zigbee, and 2.4-GHz exclusive.

nRF52820 can deal with all Bluetooth 5/5.1/5.2 renditions with highlights, for example, Long Range, 2 Mbps throughput, heading discovering, LE power control, and LE isochronous channels. The SoC additionally happens to incorporate a Full Speed (12 Mbps) USB 2.0 interface.

The nRF52820 highlights a powerful 64-MHz 32-piece Arm® Cortex®-M4 processor and incorporates 256 KB Flash and 32 KB RAM making it a perfect single-chip alternative for a wide range of business and industrial wireless applications including proficient lighting, resource following, HID, and gaming items.

The nRF52820 when combined with an application MCU, its outstanding performance multiprotocol radio and +8 dBm output power makes it a perfect system processor for portals and other tech savvy home applications requiring propelled wireless availability. The nRF52820 is equipped for activity over an all-inclusive industrial temperature range of - 40 to 105 °C, making it appropriate for business and industrial applications, including proficient lighting.

“The nRF52820 extends the mature and proven nRF52 Series hardware and software platform with a Bluetooth 5.2 multiprotocol SoC for budget-constrained applications,” adds Kjetil Holstad, Director of Product Management with Nordic Semiconductor. “The nRF52 Series is now the ideal platform upon which ODMs and OEMs can base all their short range wireless products. The common hardware and software architecture across the series results in excellent software portability, increasing software reusability while lowering time-to-market and development cost.”
