1 General Description
Ready for Bluetooth 5 and high grade IoT security
The SKB501 is an advanced, highly flexible single chip solution for today’s increasingly demanding ULP wireless applications for connected devices on our person, connected living environments and the IoT at large. It is designed ready for the major feature advancements of Bluetooth® 5 and takes advantage of Bluetooth 5’s increased performance capabilities which include long range and high throughput modes. Inherent industry-grade security is essential in today’s applications.
Bluetooth 5 – Bluetooth low energy further and faster
The nRF52840 is ready to take advantage of the considerable performance improvements for Bluetooth low energy with the arrival of the Bluetooth 5 specification. Of greatest importance is the support for longer range (up to x4 compared to Bluetooth 4.x) and doubling of on-air data-rate, up to 2Mbs from 1Mbs in Bluetooth 4.x
Wide protocol support with addition of 802.15.4
The 802.15.4 PHY and MAC layers are supported natively on the nRF52840. This allows nRF52840 to be used in a wide range of home and industrial sensor network applications as it supports two of the most popular wireless sensor standards in use today, Bluetooth low energy and 802.15.4 derivatives. This adds to the already existing radio support for Bluetooth low energy, ANT/ANT+ and 2.4GHz for proprietary.
