Telink BLE + IEEE802.15.4 Multi Standard Wireless SoCs

Telink's new generation TLSR8x5x family presents state of the art ultra low power (ULP) concurrent multi-protocol IoT solution at ISM 2.4GHz band.

It supports BLE 5.0 with 2X data rate, 4X long range (LR), 8X advertising packet extension (AE), up to 8 antennas for Indoor Positioning, both Telink proprietary and SIG BLE Mesh, Zigbee, RF4CE, HomeKit, Thread, ANT and 2.4GHz proprietary. It provides 32-bit MCU, BLE/802.15.4 2.4GHz Radio, 64KB SRAM, 512KB Flash, 14bit ADC with PGA, AMIC, DMIC, stereo audio output, 6-channel PWM, one quadrature decoder (QDEC), and flexible GPIO interfaces, and other peripheral blocks required for IoT applications.

The TLSR8x5x family also includes multi-stage power management design allowing ultra low power operation and making it the ideal candidate for wearable and power constraint applications. All optional features of BT 5.0, ZigBee 3.0 certification, Thread v1.1 and HomeKit authentication are already embedded with no additional external devices required.

The new 825x family is a world beater in the LP RF Connectivity.
