SE050: Mifare SAM functionality + current consumption

Hello,

I have several questions about the SE050.

- The data sheet says that the SE050 also has a "MIFARE SAM functionality". But I didn't find any further information about it, neither in the datasheet nor in the application notes. When will more information on this topic be available?

- In the data sheet under "14.1.3 Power consumption" the currents of the SE050 in the different operating modes are indicated. How high is the supply voltage for this information?

- In the data sheet it is stated under "14.1.3 Power consumption" that fCPU=48MHz. Is it possible to operate the SE050 with a slower clock frequency to further reduce the current?

Best regards,
Tim

-No, it is not possible, BTW, what is the usecase? why current consumption should be limited? Please help to clarify.

Have a great day,
Kan
