Datasheet
VS2
Voltage Sense 2: This pin is used in
conjunction with VS1 to determine the
operating voltage of the card. This pin is
internally pulled high to the voltage of the
+5V power pin. This pin should be
connected to PCMCIA socket pin 57.

SOCKET_VCC
This pin can be connected to either a 3.3-
or 5-volt power supply. The socket
interface outputs (listed in this table, Table
2) will operate at the voltage applied to
these pins, independent of the voltage
applied to other PD6729 pin groups.
Connect these pins to the VCC supply of
the socket (pins 17 and 51 of the
respective PCMCIA socket).

NOTES:
1. To differentiate the sockets, all socket-specific pins have either A_ or B_ prepended to the pin names indicated. For example,
A_A[25:0] and B_A[25:0] are the independent address buses to the sockets.
2. When a socket is configured as an ATA drive interface, socket interface pin functions change. See “ATA Mode Operation” on
page 91.
