BR3579: 1080P 2M Pixel H265(HEVC)/H264(AVC)/MJPEG SPI Video Controller


BR3579 provides a video streaming by serial interface SPI to transmit it to MCU, SOC, WiFi-SoC for AloT applications.
BR3579 has a built-in multiple video compression engine H265/H264/MJPEG to reduce the video size to transmit faster and save storage space.
Image cropping function is crucial for AIoT. By cropping ROI (region of interest, a partial area of an image) of photos, BR3579 offers lower data size and higher image resolution. BR3579 has equipped with remarkable IoT features. It is low power consumption and has a short wake-up time.
BR3579 provides a higher data rate interface SPI up to 15Mbps. It is suitable for MCU-based applications due to SPI universality. MCU products can then effortlessly implement images and add to their functions.
Wireless is a general way for AI or AIoT to grab image data for analysis. For wireless MCU-based applications, transmitting solutions such as WiFi, Sub-GHz, Blue Tooth, and LTE 4G are also available.
