Bluetooth 5 SoC targets cost sensitive, mass-market wireless devices: Page 2 of 2

October 23, 2017 // By Julien Happich
Nordic Semiconductor has announced that its nRF52810 Bluetooth Low Energy (Bluetooth LE) System-on-Chip, a memory-optimized addition to the company's nRF52 Series high-performance Bluetooth 5-certified SoCs, is now available in high volume.

The S112 SoftDevice is an extensively-tested, optimized, lightweight stack designed to complement the nRF52810 SoC's 196kB Flash/24kB RAM allocation. The S112 SoftDevice occupies just 100kB, ensuring ample spare memory for a wide range of mass-market Bluetooth LE applications and robust support for OTA application software upgrades.

To optimize the performance of the nRF52810 SoC, the S112 SoftDevice is a dual peripheral/broadcaster only stack but retains the Bluetooth 5/Bluetooth LE features of: 2 Mbps throughput; Privacy 1.2; LE secure connections; LE Ping; Long ATT MTU; Timeslot API enabling use with Bluetooth mesh or other proprietary protocols; and PA/LNA control function.

The key advantages of Bluetooth 5 compared with previous versions of the standard include: 2x the on-air data bandwidth (2 Mbps) compared with the Bluetooth LE implementation of Bluetooth 4.2; and 8x the broadcasting ability with advertising extensions that increase the advertising packet payload size to 251 bytes for more efficient data transfer, particularly in beacon applications.
