The TLSR8258 with internal Flash and audio support combines the features and functions needed for all 2.4GHz IoT standards into a single SoC. It supports standards and industrial alliance specifications including Bluetooth Low Energy (up to Bluetooth 5, with up to 8 antenna indoor positioning support), BLE Mesh, Zigbee, RF4CE, HomeKit, 6LoWPAN, Thread, ANT and 2.4GHz proprietary standard. For some use cases, the TLSR8258 supports concurrent multi-standards.

The TLSR8258 integrates a power-balanced 32-bit MCU, BLE/802.15.4/2.4GHz Radio, 64kB SRAM, 512kB Flash, 14bit ADC with PGA, Analog and Digital Microphone input, stereo audio output, 6-channel PWM, one quadrature decoder (QDEC), flexible IO interfaces, and other peripheral blocks required for IoT (Internet of Things) applications. The TLSR8258 also includes multi-stage power management design allowing ultra-low power operation and making it the ideal candidate for wearable and power-constraint applications.
