System Controller Data Input/Output. An open-drain IO with a 20kΩ pull-up
resistor to DV
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.
Supply Voltage for System Controller Digital Pins. Set at +1.4V to +5.5V.
System Controller Clock Input
System Controller Reset Input
Optional System Controller Data Input. Connect to controllers without an open-drain out-
put. When not used, connect DDRV to DV
Shutdown Mode Input. Driving SHDN low reduces the total supply current to less than
1µA. 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 DV
System Controller and Card Ground
Reset Output to Card. Actively pulled low during shutdown.
Clock Output to Card. 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.
Card-Side Bidirectional Input/Output. An open-drain output with a 10kΩ pull-up resistor to
V
ing 1mA while pulling IO low. Actively pulled low during shutdown.
