Bluetooth Low Energy 5.1 / zigbee / 2.4GHz Multi-Mode SoC

Description and Features

The  Bluetooth Low Energy (BLE) 5.1/15.4 /2.4Ghz Nordic compliant chip with internal Flash and audio support combines the features and functions needed for all 2.4GHz IoT standards. It supports multiple standards including Bluetooth Low Energy (BLE) 5.1 with up to 8 antenna indoor positioning support, Bluetooth Low Energy (BLE) Mesh, Zigbee, RF4CE, HomeKit, 6LoWPAN, Thread, ANT and 2.4GHz proprietary (Nordic Compatible) standards. The T8278’s embedded FLASH enables dynamic stack and profile configuration, and the final end product functionality is configurable via software, providing ultimate flexibility. The T8278 also has hardware OTA upgrades support and multiple boot switching, allowing convenient product feature roll outs and upgrades. The Multi Mode SoC supports concurrent multi-standards, for example, stacks such as Bluetooth Low Energy (BLE) and 802.15.4 can run concurrently with one application state but dual radio communication channels for interacting with different devices. The end product working in this mode can maintain active Bluetooth Smart connections to smart phones or other Bluetooth Low Energy (BLE) devices while control and communicate with 802.15.4 or other 2.4GHz devices at the same time. The 8278 supports single-channel analog mic or dual-channel digital microphone, and stereo audio output with enhanced voice performance for voice search and other such applications. The SoC have passed ETSI EN 300 328 and EN 300 440 Class 2 (Europe), FCC CFR47 Part 15 (US) and ARIB STD-T66 (Japan) certification.  Bluetooth-Low-Energy-Zigbee-2.4GHz-Nordic-SoC-supplier-in-china
