DATA I/O LEVEL SHIFTER
The level shifter accommodates the voltage difference
that might exist between the microcontroller and the smart
card. A pulsed accelerator built-in circuit provides the fast
positive going transient according to the ISO7816-3
specifications. The basic I/O level shifter is depicted in
Figure 7.

Figure 7. Basic I/O Internal Circuit
The transaction is valid when the Chip Select pin is Low,
the I/O signal being Open Drain or Totem Pole on either
sides.
Since the device can operate either in a single or a multiple
card system, provisions have been made to avoid CRD_IO
current overload. Depending upon the selected mode of
operation (ASYNC. or Sync), the card I/O line is
respectively connected to either I/O pin 1, or to the MOSI
register byte bit 2. On the other hand, the logic level present
at the card I/O is feedback to the C via the MISO register
bit 3. The logic level present at pin 6 controls the connection
of the internal pull up as depicted in Table 6.
