>
> From: Meenakshi Aggarwal
>
> LX2162 is LX2160 based SoC, it has same die as of LX2160
> with different packaging.
>
> LX2162A support 64-bit 2.9GT/s DDR4 memory, i2c, micro-click module,
> microSD card, eMMC support, serial console, qspi nor flash, qsgmii,
> sgmii, 25g, 40g, 50g network interface, one usb 3.0 and serdes
> interface to support three PCIe gen3 interface.
