Hi,

The Secure Digital Host Controller (SDHC) module included on Kinetis supports the specification version 2.0 of SDCard.org; this specification supports SD Cards up to 32 GB. You can find this at the SDHC chapter of the K70’s Reference Manual.

As for the alpha numeric keypad, K70 do not support it directly but we had provide an GPIO expander which make this available.
