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 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 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 had started mass production of the chip, which would supposedly sell for as low as $4 per unit.

A5x family

In April 2019, Allwinner announced the A50 28 nm quad-core SoC. The A50 features four Cortex-A7 cores running up to 1.8 GHz with 512 KB L2 cache and a Mali-400 MP2 GPU.

A6x family

In June 2017, Allwinner announced the A63 28 nm quad-core SoC at APC 2017 Conference. The A63 features four Cortex-A53 cores running up to 1.8 GHz with 512 KB L2 cache and a Mali-T760 MP2 GPU with OpenGL ES 3.2 support.

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

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.
