The Silicon BLE5.1/15.4 chip with internal Flash and audio support combines the features and functions needed for all 2.4GHz IoT standards. It supports standards and industrial alliance specifications including BLE 5.0 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 8258 supports concurrent multi-standards.
The chip integrates strong 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 8258 also includes multi-stage power management design allowing ultra-low power operation and making it the ideal candidate for wearable and power-constraint applications.
This is available as the white label chip or any custom modification as per your requirement.
