Overview
The Allwinner A523 (sun55iw3) SoC features two quad-core Arm Cortex-A55 CPU clusters (for a total of eight cores), a Arm Mali-G57 MC1-2EE GPU, and a XuanTie E906 RISC-V management core. It is mainly targeted at tablet computers, though PCIe, USB 3.0, eDP and a Gigabit Ethernet MAC open up more use cases.
The USB 3.0 controller and the single lane PCIe 2.1 controller share the output pins, via a combo-PHY, so cannot be used at the same time.
