Wi-Fi 6 + Bluetooth LE 5.1 Combo SoC

ASR5955S is a highly integrated, high performance, and low cost transceiver chip which supports both 1x1 IEEE 802.11b/g/n/ax and Bluetooth 5.1 Low Energy (BLE) for the Internet of Things (IoT). The ASR5955S integrates RF transceiver, 802.11 PHY+MAC, BLE PHY+MAC, SDIO 2.0 interface, other advanced peripheral interfaces, Real Time Counter (RTC) and power management circuits. The integrated RF and analog circuit incorporate T/R switch, RF balun, power amplifier, low-noise amplifier, and entire power management modules. Therefore, the ASR5955S provides a small form-factor solution with minimal external components as a SDIO slave for data transmission or high-speed applications, such as access points, digital TV set, set-top-box, tablet PC (PAD), IP camera, Wi-Fi module, conventional TV set, customer premise equipment and more.
