Smart Card Power Select
The DS8313/DS8314 support three smart card VCC
voltages: 1.8V, 3V, and 5V. The power select is con-
trolled 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 assert-
ed 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 DS8313/DS8314 enter 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 recommended sequence of changing
the VCC range.
