(BLE + IEEE802.15.4 Multi-Standard Wireless SoC)

General Description

The TLSR8269F512 is Telink-developed BLE + IEEE802.15.4 multi-standard wireless SoC solution, which combines the features and functions needed for all 2.4GHz IoT standards into a single SoC.

The TLSR8269F512 supports standards and industrial alliance specifications including Bluetooth Smart (BLE4.0 and BLE4.2), BLE Mesh, 6LoWPAN, Thread, Zigbee, RF4CE, HomeKit and 2.4GHz proprietary protocols. The TLSR8269F512 also have hardware OTA upgrades support and multiple boot switching, allowing convenient product feature roll outs and upgrades. The TLSR8269F512 can also support concurrent multi-standards in which stacks such as RF4CE and BLE can run simultaneously.

The TLSR8269F512 integrates strong 32-bit MCU, BLE/802.15.4/2.4G Radio, 32KB SRAM, 512KB internal Flash, 14bit ADC with PGA, Analog and Digital Microphone input, 6-channel PWM (2-channel IR), one quadrature decoder (QDEC), abundant GPIO interfaces, multi-stage power management module and nearly all the peripherals needed for IoT (Internet of Things) and human interface devices application development.

The TLSR8269F512 is completely RoHS-compliant and 100% lead (Pb)-free.
