Overview
The TXW828 is a low-power, high-performance, highly integrated audio and video wireless SoC chip. It integrates 2.4GHz Wi-Fi, BLE, high-performance ISP image processing, and H.264/MJPEG codec internally, offering excellent RF performance, superior image processing capabilities, encoding quality, and relatively low bit rates. It also includes an internal security algorithm acceleration engine and features a complete set of peripheral interfaces: audio ADC/DAC, MIPI CSI-2, MIPI DSI, DVP, LCD, RMII MAC, USB 2.0 High Speed Host/Device, SDMMC Host, I2S, PDM, and many other rich peripheral interfaces.
