Chip Enable 3 Input, active LOW. Sampled on the rising edge
of CLK. Used in conjunction with CE
the device.
Output Enable, asynchronous input, active LOW. Combined
with the synchronous logic block inside the device to control the
direction of the I/O pins. When LOW, the I/O pins are allowed
to behave as outputs. When deasserted HIGH, I/O pins are
three-stated, and act as input data pins. OE is masked during
the data portion of a write sequence, during the first clock when
emerging from a deselected state, when the device has been
deselected.
Clock Enable Input, active LOW. When asserted LOW the
Clock signal is recognized by the SRAM. When deasserted
HIGH the Clock signal is masked. Since deasserting CEN does
not deselect the device, CEN can be used to extend the previ-
ous cycle when required.
ZZ “sleep” Input. This active HIGH input places the device in
a non-time critical “sleep” condition with data integrity pre-
served. During normal operation, this pin can be connected to
Vss or left floating.
Bidirectional Data I/O Lines. As inputs, they feed into an
on-chip data register that is triggered by the rising edge of CLK.
As outputs, they deliver the data contained in the memory loca-
tion specified by address during the clock rise of the read cycle.
The direction of the pins is controlled by OE and the internal
control logic. When OE is asserted LOW, the pins can behave
as outputs. When HIGH, DQ
three-state condition. The outputs are automatically three-stat-
ed during the data portion of a write sequence, during the first
clock when emerging from a deselected state, and when the
device is deselected, regardless of the state of OE.
Bidirectional Data Parity I/O Lines. Functionally, these signals
are identical to DQ
