PD6710/22 ISA-to-PC-Card (PCMCIA) Controllers  
Power Type  
Output or Pull-up Power Source  
B_SOCKET_VCC: powered from the Socket  
3
B V supply connecting to PC Card pins 17  
CC  
and 51 of Socket B  
ISA_VCC: powered from the ISA bus power  
supply  
4
5
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 Specificationson page 101 for more information). Note that the drive type listed for an  
input-only (I) pin is not applicable ().

ISA Bus Address Input: Connect to ISA  
signals LA[23:17] or, for systems limited to  
1-Mbyte address space, tie ALE high,  
ground LA[23:20] and connect LA[19:17] to  
ISA signals SA[19:17].
