Smart Card Power Select
The device supports three smart card VCC voltages:
1.8V, 3V, and 5V. The power select is controlled by the
1_8V and 5V/3V signals as shown in Table 3. The 1_8V
signal has priority over 5V/3V. When 1_8V is asserted
high, 1.8V is applied to VCC when the smart card is
active. When 1_8V is deasserted, 5V/3V dictates VCC
power range. VCC is 5V if 5V/3V is asserted to a logic-
high state, and VCC is 3V if 5V/3V is pulled to a
logic-low state. Care must be exercised when switching
from one VCC power selection to the other. If both 1_8V
and 5V/3V are high with CMDVCC high at the same
time, the device enters stop mode. To avoid accidental
entry into stop mode, the state of 1_8V and 5V/3V must
not be changed simultaneously. A minimum delay of
100ns should be observed between changing the
states of 1_8V and 5V/3V. See Figure 9 for the recom-
mended sequence of changing the VCC range.
