Allwinner A33

Devices
Allwinner A33 (sun8i) SoC features a Quad-Core Cortex-A7 ARM CPU, and a Mali400 MP2 GPU from ARM. It is a Quad-Core pin-to-pin-compatible version of A23 (which in turn is a lower power, cut-down, not-pin-compatible version of the A20).

It's now also called R16, targeted on miscellaneous IoT devices, such as Nintendo NES Classic Edition gaming console.
