PD6710/’22 — ISA-to-PC-Card (PCMCIA) Controllers
Power Type
3
4
5
Output or Pull-up Power Source
B_SOCKET_VCC: powered from the Socket
B VCC supply connecting to PC Card pins 17
and 51 of Socket B
ISA_VCC: powered from the ISA bus power
supply
CORE_VDD: usually powered from the
lowest available power supply for lowest
power consumption, which in most systems
is 3.3 volts
Note: All pin inputs are referenced to CORE_VDD, independent of their output supply voltage.
The drive-type (Drive) column describes the output drive-type of the pin (see DC specifications in
“Electrical Specifications” on page 101 for more information). Note that the drive type listed for an
input-only (I) pin is not applicable (–).

ISA Bus Data Input/Output: These pins are 71, 73–75, 77, 134–137, 139,
used to transfer data during a memory or I/O 79–81, 140, 141–143, 200,
cycle. Connect to ISA signals SD[15:0].
