TLSR921x Series TLSR827x Series TLSR825x Series

TLSR827x Series

The TLSR827x Series is capable of supporting Bluetooth Low Power, Bluetooth Mesh, Zigbee, RF4CE, Apple HomeKit, Apple Find My network, and 2.4GHz proprietary protocols within a single chip. Moreover, it supports the Bluetooth low - power Angle finding function. It integrates RF inductance, which helps to reduce the Bill of Materials (BOM). The audio function is enhanced, and there is a wider supply voltage range. Additionally, a Wi - Fi PTA hardware interface is reserved, further enhancing the DCDC efficiency and reducing the system power consumption.
