This pin is an active low read strobe signal for CF
device.
This pin is an active low write strobe signal for CF
device.
This pin is an active low write protect signal for the SM
device.
This pin has a weak pull-down resistor that is
permanently enabled
This pin is an active high Address Latch Enable signal
for the SM device.
This pin has a weak pull-down resistor that is
permanently enabled
This pin is an active high Command Latch Enable signal
for the SM device.
This pin has a weak pull-down resistor that is
permanently enabled
These pins are the bi-directional data signal SM_D7-
SM_D0.
The bi-directional data signal has an internal weak pull-
down resistor.
This pin is an active low read strobe signal for SM
device.
When using the internal FET, this pin has an internal
weak pull-up resistor that is tied to the output of the
internal Power FET.
If an external FET is used (Internal FET is disabled),
then the internal pull-up is not available (external pull-
ups must be used, and should be connected to the
applicable Card Power Supply).
This pin is an active low write strobe signal for SM
device.
When using the internal FET, this pin has an internal
weak pull-up resistor that is tied to the output of the
internal Power FET.
If an external FET is used (Internal FET is disabled),
then the internal pull-up is not available (external pull-
ups must be used, and should be connected to the
applicable Card Power Supply).
A write-protect seal is detected, when this pin is low.
This pin has an internally controlled weak pull-up
resistor.
This pin is connected to the BSY/RDY pin of the SM
device.
An external pull-up resistor is required on this signal.
The pull-up resistor must be pulled up to the same
power source that powers the SM/NAND flash device.
