Input-
Synchronous
Address Inputs used to select one of the 512K
address locations
. Sampled at the rising edge of
the CLK if ADSP or ADSC is active LOW, and CE
1
,
CE
2
, and
CE
3[2]
are sampled active. A

are fed
to the two-bit counter..

Input-
Synchronous
Byte Write Select Inputs, active LOW
. Qualified
with BWE to conduct Byte Writes to the SRAM.
Sampled on the rising edge of CLK.
GW

88
H4
B7
Input-
Synchronous
Global Write Enable Input, active LOW
. When
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).
BWE
87

M4
A7
Input-
Synchronous
Byte Write Enable Input, active LOW
. Sampled
on the rising edge of CLK. This signal must be
asserted LOW to conduct a Byte Write.
CLK

K4
B6
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.
CE

E4
A3
Input-
Synchronous
Chip Enable 1 Input, active LOW
. Sampled on
the 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.
CE
2

B2
B3
Input-
Synchronous
Chip Enable 2 Input, active HIGH
. Sampled on
the rising edge of CLK. Used in conjunction with
CE
1
and CE
3[2]
to select/deselect the device.
CE
3 [2]
92

A6
Input-
Synchronous
Chip Enable 3 Input, active LOW
. Sampled on
the 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.
OE

86
F4
B8
Input-
Asynchronous
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.
ADV
83
83
G4
A9
Input-
Synchronous
Advance Input signal, sampled on the rising
edge of CLK, active LOW
. When asserted, it
automatically increments the address in a burst
cycle.
