Input-
Byte Write Select Inputs, active LOW.
Qualified
Synchronous with BWE to conduct Byte Writes to the SRAM.
Sampled on the rising edge of CLK.
Input-
Global Write Enable Input, active LOW.
When
Synchronous asserted LOW on the rising edge of CLK, a global
Write is conducted (ALL bytes are written,
regardless of the values on BW
X
and BWE).
Input-
Byte Write Enable Input, active LOW.
Sampled
Synchronous on the rising edge of CLK. This signal must be as-
serted LOW to conduct a Byte Write.
Input-
Clock
Clock Input.
Used to capture all synchronous
inputs to the device. Also used to increment the
burst counter when ADV is asserted LOW, during a
burst operation.

Input-
Chip Enable 1 Input, active LOW.
Sampled on the
Synchronous rising edge of CLK. Used in conjunction with CE
2
and CE
3[2]
to select/deselect the device. ADSP is
ignored if CE
1
is HIGH.
Input-
Chip Enable 2 Input, active HIGH.
Sampled on
Synchronous the rising edge of CLK. Used in conjunction with
CE
1
and CE
3[2]
to select/deselect the device.
Input-
Chip Enable 3 Input, active LOW.
Sampled on the
Synchronous rising edge of CLK. Used in conjunction with CE
1
and CE
2
to select/deselect the device. Not available
for AJ package version. Not connected for BGA.
Where referenced, CE
3[2]
is assumed active
throughout this document for BGA.
Input-
Asynchro-
nous
Output Enable, asynchronous input, active
LOW.
Controls the direction of the I/O pins. When
LOW, the I/O pins behave as outputs. When
deasserted HIGH, I/O pins are three-stated, and act
as input data pins. OE is masked during the first
clock of a read cycle when emerging from a
deselected state.

When asserted, it
automatically increments the address in a burst
cycle.
