I/O8PD
SM Data 7-0:
These pins are the bi-directional data signal SM_D7-SM_D0.
The bi-directional data signal has an internal weak pull-down
resistor.
SM_nRE
81
08PU
SM Read Enable:
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.
08
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).
SM_nWE
82
O8PU
SM Write Enable:
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.
08
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).
SM_nWPS
76
IPU
SM Write Protect Switch:
A write-protect seal is detected, when this pin is low.
This pin has an internally controlled weak pull-up resistor.
SM_nB/R
77
I
SM Busy or Data Ready:
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.
SM_nCE
83
O8PU
SM Chip Enable:
This pin is the active low chip enable signal to the 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.
08
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).
SM_nCD
78
IPU
SM Card Detection:
This is the card detection signal from SM device to indicate if
the device is inserted.
This pin has an internally controlled weak pull-up resistor.
