Functional description
6.10
Card supply voltage (VCC) selection
6.10.1
Automatic determining of card supply voltage (VCC) - all versions
except ST8034P
The supply voltage (VCC) that the card requires is determined automatically by monitoring
the duration of the high state on the CMDVCC pin before the activation command CMDVCC
falling edge occurs. If the CMDVCC pin stays high for more than 30 ms (tW_VCC), the
activation is done with VCC = 5 V. If the CMDVCC pin stays high for less than 15 ms, the
activation is done with VCC = 3 V.
To activate the card at VCC = 5 V, the CMDVCC pin must stay high for tW_VCC > 30 ms
before going low:
Figure 16. Card activation to VCC = 5 V (tW_VCC > 30 ms)
To activate the card at VCC = 3 V, the CMDVCC pin must stay high for tW_VCC < 15 ms
before going low:
Figure 17. Card activation to VCC = 3 V (tW_VCC < 15 ms)
