4th Generation USB2.0 Flash Media Controller with Integrated Card Power FETs
Datasheet
SMSC USB2227/USB2228
15
Revision 1.77 (06-13-05)
DATASHEET
SM
Write Enable
SM_nWE
O8PU
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
Write Protect Switch
SM_nWPS
IPU
A write-protect seal is detected, when this pin is low.
This pin has an internally controlled weak pull-up
resistor.
SM
Busy or Data Ready
SM_nB/R
I
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
Chip Enable
SM_nCE
O8PU
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
Card Detection
SM_nCD
IPU
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.
MEMORY STICK INTERFACE
MS
Bus State
MS_BS
O8
This pin is connected to the BS pin of the MS device.
It is used to control the Bus States 0, 1, 2 and 3 (BS0,
BS1, BS2 and BS3) of the MS device.
MS
System
Data In/Out
MS_SDIO/MS_
D0
I/O8PD
This pin is a bi-directional data signal for the MS device.
Most significant bit (MSB) of each byte is transmitted
first by either MSC or MS device.
The bi-directional data signal has an internal weak pull-
down resistor.
MS
System Data In/Out
MS_D1
I/O8PD
This pin is a bi-directional data signal for the MS device.
This pin has internally controlled weak pull-up and pull-
down resistors for various operational modes.
MS
System
Data In/Out
MS_D[3:2]
I/O8PD
This pin is a bi-directional data signal for the MS device.
The bi-directional data signal has an internal weak pull-
down resistor.
