A2x and A3x family

In December 2012, Allwinner announced the availability of two ARM Cortex-A7 MPCore powered products, the dual-core Allwinner A20 and quad-core Allwinner A31. Production of the A31 started in September 2012 and end products, mostly high-end tablets from Chinese manufacturers, appeared on the market in early 2013, including the Onda V972. Allwinner was the first to make this ARM processor core available in mass production. In March 2013, Allwinner launched its quad-core Phablet processor A31s. Based on quad-core cortex-A7 CPU architecture, this processor allows 3G, 2G, LTE, WIFI, BT, FM, GPS, AGPS and NFC using a minimum of external components. In October, 2013, Allwinner released its second dual-core A23, touted to be "The most efficient dual core processor" for tablets. The A23's CPU frequency was intended to run up to 1.5 GHz. In June, 2014, Allwinner announced the A33 quad-core SoC that is pin compatible with Allwinner's A23. The new SoC features four Cortex-A7 cores with 256 KB L1 cache, 512 KB L2 cache and a Mali-400 MP2 GPU. A new feature is the support of the

Allwinner processor ecosystem

Allwinner Technology cooperates with around ten independent design houses (IDHs) based in Shenzhen, China, who develop solutions based on Allwinner processors. They include iNet Technology, Worldchip Digital Technology, Sochip Technology, Topwise Communication, ChipHD Technology, Highcharacter Science and Technology, WITS Technology, Ococci Technology, Next Huawen Technology, and Qi Hao Digital Technology. Apart from the white-box market, Allwinner processors can also be found in many brand products, including HP, MSI, ZTE, NOOX, GoTab, Skyworth, MeLE, Polaroid, Micromax, Archos, Texet, Ainol, Onda, Ramos, Teclast, Ployer, Readboy, Noah, RF, Bmorn, Apical, Astro Queo, etc.

Free and open-source software support

Due to the low price of the A10 SoC, the fact that it has a special rescue mode, and the early availability of U-Boot and Linux kernel source (through several device makers), the Allwinner SoCs have been popular among open-source software developers. Since at least 2012 the linux-sunxi community has been one of the most active ARM SoC communities, and the slightly older hardware has only very minimal dependence on firmware or blobs. Since 2014 Allwinner is also an official member of the

Linux controversies

GPL controversy

Allwinner has been accused multiple times of violating the GPL license by not providing Linux/Android kernel source code or U-Boot source, and by using LGPL-licensed code within their binary blobs, etc.

Backdoor controversy

Allwinner has also been accused of including a

in its published version of the Linux kernel. The backdoor allows any installed app to have full root access to the system. While this may be a remnant of debugging during the development process, it presents a significant security risk to all devices using the Allwinner provided kernel.
