Chapter 5 Pin Descriptions
This section provides a detailed description of each signal. The signals are arranged in functional
groups according to their associated interface.
The “n” symbol in the signal name indicates that the active, or asserted, state occurs when the signal
is at a low voltage level. When “n” is not present before the signal name, the signal is asserted at the
high voltage level.
The terms assertion and negation are used exclusively. This is done to avoid confusion when working
with a mixture of “active low” and “active high” signals. The term assert, or assertion, indicates that a
signal is active, independent of whether that level is represented by a high or low voltage. The term
negate, or negation, indicates that a signal is inactive.

This pin is an active low read strobe signal for xD

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, and is controlled by the SM_PU
bit of the SM_CTL register.
If an external FET is used (Internal FET is disabled),
then the internal pull-up is not available (external
pull-ups must be used).

O12PU
This pin is an active low write strobe signal for xD
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, and is controlled by the SM_PU
bit of the SM_CTL register.
If an external FET is used (Internal FET is disabled),
then the internal pull-up is not available (external
pull-ups must be used).

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, and is controlled by the SM_PU
bit of the SM_CTL register.
If an external FET is used (Internal FET is disabled),
then the internal pull-up is not available (external

has a pull down resistor if in parallel mode,
otherwise it is disabled. In 4 or 8 bit parallel mode,
there is a weak pull-down resistor on all MS_D7 - 0

Note 7.1 Stresses above the specified parameters may cause permanent damage to the device.
This is a stress rating only and functional operation of the device at any condition above
those indicated in the operation sections of this specification is not implied.
Note 7.2 When powering this device from laboratory or system power supplies, it is important that
the Absolute Maximum Ratings not be exceeded or device failure can result. Some power
supplies exhibit voltage spikes on their outputs when the AC power is switched on or off.
In addition, voltage transients on the AC power line may appear on the DC output. When
this possibility exists, it is suggested that a clamp circuit be used.
