SE050F2 as Smart card interface

[hitesh_gambhava]

Hi NXP team,

I have a query with SE050F2 secure element. Can it work as smart card over I2C interface or it is must to use ISO 7816 to get this functionality?

Thanks,

Hitesh

Hi Kan,

Thanks for the response. My question is more about as classic Smart card interface i.e. from PC/Laptop USB to K64F USB (over CCID) and K64F to SE050 over I2C interface. As per your response it looks this is possible. Please confirm.

Thanks,

Hitesh

Hi @hitesh_gambhava ,

Yes, you may use either of the following CCID examples out of the MW for evaluation purpose.

and after plugging into a Laptop, you will find the following notification.

Regarding how to program the bin file into the K64F-FRDM board, please kindly refer to "3.3 Flash FRDM-K64F with VCOM software " in https://www.nxp.com.cn/docs/en/application-note/AN12398.pdf for details.

Hope that helps,

Have a great day,
Kan

Hi @hitesh_gambhava ,

Not sure what is the requirement meant when you specified "smart card interface". SE050F is a "smart card". It can receive commands using the interfaces I²C (using T1oI2C protocol), and ISO14443. When you place the NFC antenna over a contactless reader, it will be discovered as a smart card. The contact based ISO7816 interface is a classic smart card interface, but it does not matter of the commands are exchanges over contact, contactless or I2C interface. Over all interfaces the SE05x can be made recognized by an system as "smart card". E.g. for the I2C interface the K64F CCID example can be used which shows the connected SE05x as a smart card to a host system. Most likely your question is if the SE050F then supports the commands expected by the system, right? Please kindly clarify.

Have a great day,
Kan
