BC840M Advanced Features

Protocols

Bluetooth 5 datarate: 2Mbps, 1Mbps, 500 Kbps, 125 kbps
IEEE 802.15.4 Thread and Zigbee
ANT/ANT+
Nordic 2.4 GHz proprietary

Power Supply

1.7V to 3.6V DC power supply
High voltage power supply to accept up to 5.5V DC for direct connection to Lithium batteries or 5V system power. An external voltage regulator is not required. Your total system cost can be lower and your PCB size can be smaller.

Security

Embedded CryptoCell 310 co-processor can be used to provide more secure connection and to prevent hacker.
BC840M is required if your Bluetooth 5 devices are used in mesh networks with many nodes for desirable performance. Security is mandatory in Bluetooth mesh networks. By offloading decryption, encryption, and authentication works to CryptoCell-310, BC840M Series can deliver high performance in Bluetooth mesh networks.
