DATASHEET
CF
Card Detection2
CF_nCD2
IPU
This card detection pin is connected to the ground on
the CF device, when the CF device is inserted.
This pin has an internally controlled weak pull-up
resistor.
CF
Card Detection1
CF_nCD1
IPU
This card detection pin is connected to ground on the
CF device, when the CF device is inserted.
This pin has an internally controlled weak pull-up
resistor.
CF
Hardware Reset
CF_nRESET
O8
This pin is an active low hardware reset signal to CF
device.
CF
IO Read
CF_nIOR
O8
This pin is an active low read strobe signal for CF
device.
CF
IO Write Strobe
CF_nIOW
O8
This pin is an active low write strobe signal for CF
device.
SmartMedia INTERFACE
SM
Write Protect
SM_nWP
O8PD
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
SM
Address Strobe
SM_ALE
O8PD
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
SM
Command Strobe
SM_CLE
O8PD
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
SM
Data7-0
SM_D[7:0]
I/O8PD
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
Read Enable
SM_nRE
08PU
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).
