In 2012 and 2013, Allwinner was the number one supplier in terms of unit shipments of application processors for Android tablets worldwide. According to DigiTimes, in Q4 2013 Allwinner lost its number one position in terms of unit shipments to the Chinese market to Rockchip. For Q2 2014, Allwinner was reported by DigiTimes to be the third largest supplier to the Chinese market after Rockchip and MediaTek. DigiTimes has also projected that Allwinner will fall to the number four position in Q4 2014, being passed by Intel, as Allwinner's unit shipments continue to decline.
From 2007 to 2011, Allwinner introduced its F-series processors, F10, F13, F18, F20, F1E200, F1C100, F20. This series runs Allwinner's self-developed operating system Melis2.0, which is now mainly used in vehicle multimedia system, E-ink reader, video intercom system, etc.
In 2011, the company became an ARM processor licensee, and subsequently announced a series of ARM Cortex-A8 powered mobile application processors, including A10, A13, A10s and A12, which were used in numerous tablets, and also in PC-on-a-stick and media center devices. They have also been adopted in free hardware projects like the Cubieboard development board.
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 June, 2014, Allwinner announced the A33 quad-core SoC that is pin-to-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 OpenMAX API. Allwinner has positioned the A33 for entry-level tablets, targeting quad-core tablets priced from $30 to $60, and in July 2014 announced that it has started mass production of the chip and will sell for as low as $4 per chip.
On June 30, 2014, Chinese brand Onda officially released its octa-core Onda V989 tablet, which is based on Allwinner A80. This is the first Allwinner A80-based tablet that is available to consumers, priced at CNY 1099 (~US$177).
In September 2014, Allwinner announced the Allwinner A83T, an octa-core tablet processor that packs eight highly energy-efficient Cortex-A7 cores that can run simultaneously at up to around 2.0 GHz. It also includes a PowerVR GPU. The first tablet with the chip is expected to hit the market in Q4 2014.
The V-Series are video encoding processor targeting applications such as smart DVR, IP camera and smart home applications. It is similar to the A series SoC, but adds support for functions such as digital watermarking, motion detection and video scaling, as well as a CBR/VBR bit rate control mode.
H-Series (OTT box application)
The H-series, introduced in 2014, are integrated application processors primarily targeted at OTT set-top box applications.
Allwinner has launched the A80 octa-core OTT box solution, targeting at high-end OTT box market, and launched the Allwinner H8 octa-core processor for mid-range OTT boxes, and most recently launched the quad-core Allwinner H3 targeting the US$35 - $50 OTT box market.
Android 5.0 Lollipop support
In December 2014, Allwinner released its Android 5.0 SDK for Allwinner A33 quad-core solution.
In July 2014, Allwinner announced that its first 64-bit tablet processor was to hit the market soon.
The Allwinner SoC family includes A-series, which is intended for Android OS, and F-series, which is intended for the company's self-developed Melis operating system.
The A-Series, including the A10, A20 and A31 SoCs, have a proprietary in-house designed multimedia co-processing DSP (Digital Signal Processing) processor technology for hardware accelerated video, image, and audio decoding, called CedarX (with subprocessing called "CedarV" for video decoding and "CedarA" for audio decoding), able to decode 2160p 2D and 1080p 3D video. The main disadvantages with CedarX technology and associated libraries is that Allwinner's own CedarX proprietary libraries have no clear usage license, so even if the source code for some versions is available the terms-of-use is unknown in open source software, and there is no glue code for any other multimedia frameworks on GNU/Linux systems that could be used as a middle-ware, like for example OpenMAX or VAAPI.
The A-series are integrated application processors primarily targeting tablets as well as targeting mini PCs, development boards and TV boxes.

Allwinner processor ecosystem
Allwinner Technology cooperates with around ten 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 infamous 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 binary blobs.
Since 2014 Allwinner is also an official member of the Linaro group, a non profit engineering consortium aimed at developing open source software for the ARM architecture. However, it has been noted that most of the contributions that Allwinner has made to the Linaro group has been in the form of binary blobs, which is in clear violation of the GNU GPL license that the Linux kernel uses.
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.
Allwinner has also been accused of including a backdoor in its published version of the Linux kernel. The backdoor allows root access by simply sending a text message to the device. 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.
