DATA
1
System Controller Data Input/Output. An open-drain IO with a 20k
pull-up
resistor to DVCC. For bidirectional data transfer, connect to an open-drain controller output
capable of sinking 1mA while pulling DATA low. If the controller is not open-drain, use
DDRV to send data and DATA to receive data.

VCC
Card-Side Bidirectional Input/Output. An open-drain output with a 10k
pull-up resistor to
VCC. For bidirectional data transfer, connect to an open-drain card output capable of sink-
ing 1mA while pulling IO low. Actively pulled low during shutdown.
Supply Voltage for Card-Side Digital Pins. Set at +1.7V to +5.5V. Proper supply bypassing
is required to meet ±10kV ESD specifications.
Clock Output to Card. Actively pulled low during shutdown.
Reset Output to Card. Actively pulled low during shutdown.
System Controller and Card Ground
Shutdown Mode Input. Driving SHDN low reduces the total supply current to less than
1A. In shutdown mode, RST, CLK, and IO are actively pulled low and the transfer gate
between DATA and IO is disabled. When not used, connect SHDN to DVCC.
Optional System Controller Data Input. Connect to controllers without an open-drain out-
put. When not used, connect DDRV to DVCC.
System Controller Reset Input
System Controller Clock Input
Supply Voltage for System Controller Digital Pins. Set at +1.4V to +5.5V.
