1、System Overview

      MT8167A is a highly integrated mobile computing platform incorporating application processing and connectivity subsystems to enable smart mobile applications. The chip integrates a Quad - core arm<00AE> Cortex - A35 MPCoreTM operating up to 1.GHz and a powerful multi standard video accelerator. The MT8167A interfaces to NAND flash memory, LPDDR2, LPDDR3, DDR3, DDR3L and DDR4 for optimal performance and also supports booting from EMMC to minimize the overall BOM cost. In addition, an extensive set of interfaces are include d to interface to cameras, touch screen displays, and MMC/SD cards.

    The application processor, a Quad core ARM<00AE> Cortex - A35 MPCoreTM which includes a NEON multimedia processing engine, offers processing power necessary to support the latest OpenOS along  with its demanding applications such as web browsing, email, gps navigation and games. All are viewed on a high resolution touch screen display with graphics enhanced by the 3D graphics acceleration. The multi standard video accelerator and an advanced audio subsystem are also included to provide advanced multimedia applications and services such as streaming audio and  video, a multitude of decoders and encoders such as HEVC, H.264 and MPEG 4. Audio supports include polyphonic ringtones and advanced audio fun ctions such as echo cancellation, hands - free speakerphone operation and noise cancellation.

    MT8167A includes two wireless connectivity functions,WLAN and Bluetooth The RF parts of those two blocks are also built in MT8167A chip which can support 802.11 bgn . With two advanced radio technologies integrated into one single chip,MT8167A provides the best and most convenient connectivity solution among the industry.MT8167A implements advanced and sophisticated Radio Coexistence algorithms and hardware mecha nisms.It also supports single antenna sharing among 2.4 GHz antenna for Bluetooth, WLAN. The enhanced overall quality is achieved for SIMultaneous voice, data, and audio/video transmission on Media Tablets. The small footprint with low power consumption greatly reduces the PCB layout resource.
