ISO6721-Q1: supply voltage 1.89V~2.25V

Part Number: ISO6721-Q1

Hi team,

the device has "Wide supply range: 1.71 V to 1.89 V and 2.25 V to 5.5 V". 

why the device dos not support supply voltage :1.89V to 2.25V? is there any reason?

best regards,

Kazusa suzuki

  • Hi Suzuki-san,

    Device ISO6721-Q1 is characterized for 1.8V ± 5%, 2.5V ± 10%, 3.3V ± 10% and 5V ± 10%. They are not characterized for any voltages outside of these mentioned voltages. Although we don't expect any issues between 2.25V to 5.5V, we do believe the device might not be fully operating under all test conditions for voltages between 1.89V and 2.25V. Hence, we do not recommend operating the device in this region.

    Let me know if you have any further questions, thanks.
