  • A20 Development kit is a development system based on Allwinner Technology A20 chip provided by Merrii.

     

    A20 development board showed us the powerful function of A20, it has kinds of interface and stable platform and it can be the perfect development testing platform for industries like tablet PC, advertising machineeducation, security, smart TV, smart building, industrial control, medical treatment, vehicle-mounted and mobile phone and so on, and it has deduced the development cycle of the products greatly.

     

    A20 processor with various interfaces, including quad-channel CVBS input and output,HDMI,VGA,LVDS/RGB LCD,SATA,USB and GMAC. More important, A20 processor is compatible with the pin of former A10 processor and making the product design process more simply and making design upgrading more easier.

     

    A20 processor applies the dual-core ARM Cortex-A7 CPU structure, including all the characteristic of Cortex-A15, and the A20 processor is the most energy saving processor in present ARM platform. Equipped with POWER Mail400 MP2 GPU, A20 not only improves the system performance, but also satisfy the excellent game compatibility. In addition, A20 supports 2106p video decoding and HD 1080p video decoding.

     

    Highlights Of A20

    The main specifications of A20 dual-core mobile application processor are as following:

    - Dual-core Cortex®-A7 CPU structure

    - Dual-core Mail400MP2 structure

    - H.264 2106p video playing

    - H.264 1080p@30fps 3D decoding, support BD/SBS/TAB/FP form

    - Build-in HDMI, LVDS, TV decoder and so on

    - Dual-line CMOS sensor  

    - Passed Google CTS detection, applying for GMS authority

    - Support Android 4.2.2 operating system

     

    Dual-core Cortex-A7 CPU structure

    Compare with Cortex-A8, the property of Cortex-A7 has promoted to 50% while the dimension is one-fifth of the A8 and it's efficiency is five times of the A8. The A20 dual-core mobile application processor combines with the ARM Mail400MP2GPU structure of high property and dual-core Cortex-A7CPU with high EER. It can not only satisfy the property demands of website surfing, streaming video and 2D/3D games application, but also minimize the power dissipation.

     

    Powerful HD video processing ability

    Dual-core A20 processor support 2160p video playing and 1080p/720p video decoding, bringing the best using experience for users.

     

    High level of integration

    One of the highlights of ALL WINNER SOC products is the super integration, including A20. The platform integrated LVDS,HDMI and TVdecoder, making the design more simple, making BOM cost more competitive and making the speed of product release more quickly.

     

    The pin is compatible with A10

    The pin of A20 is compatible with A10, and it can upgrade seamlessly, making the design process more simpler and upgrading more easier, decreasing the development cycle and saving the developing cost.
