query : FRDM-K64F board ISO7816 support

Hello Team,

I have FRDM-K64F Dev Board & also have ISO7816 Smartcard. I have query regarding ISO7816 support in this board.

As per 'http://www.nxp.com/assets/documents/data/en/user-guides/FRDMK64FUG.pdf' link, it says that out-of 5-UART, 1-UART supports ISO7816 comm interface.

I try to findout UART which supports ISO7816 comm interface, but i'm fail (UART0 or UART1 or any specific UART). So please tell me, which UART supports ISO7816 comm interface & also please mention pins for that UART. if possible, please provide Connecton diagram between FRDM-K64F & Smartcard.

Also need libraries & sample code to test/develop ISO7816 comm interface successfully.

& If FRDM-K64F dev board not supports ISO7816 comm interface, than please mention other NXP board(mbed OS supported), which has ISO7816 comm interface support.

Thanks, Vishal PATEL

UART0 contains the standard features plus ISO7816

Here is a wiring diagram from the community.nxp.com for another processor (K60), the relevant UART pins are in the ref manual. https://community.nxp.com/message/506388?commentID=506388#comment-506388

Thanks for your helpful reply.

Now i want to ask u another question regarding to your given answer. I failed to find ISO7816 connection pins for FRDM-K64F board (FTMn_CHx: plz provide value of n,x for FRDM-K64F board). & also which external pin(pin-name) are mapped with given internal connection diagram in case of ISO7816.

Thanks, Vishal PATEL

FTMn: There are multiple FTM's, so 'n' depends on the FTM you decide to use. CHx: Each FTM has multiple channesl, so 'x' depends on the FTM channel you decide to use.

The pin to use can be found in the signal multiplexing chapter of the K64 Reference manual.
