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 CE1,
CE2, and CE3[2] are sampled active. A1, A0 are fed
to the two-bit counter..

G3,L5
B5,A4
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
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 BWX 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
89
89
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.
CE1
98
98
E4
A3
Input-
Synchronous
Chip Enable 1 Input, active LOW. Sampled on
the rising edge of CLK. Used in conjunction with
CE2 and CE3[2] to select/deselect the device.
ADSP is ignored if CE1 is HIGH.
CE2
97
97
B2
B3
Input-
Synchronous
Chip Enable 2 Input, active HIGH. Sampled on
the rising edge of CLK. Used in conjunction with
CE1 and CE3[2] to select/deselect the device.
CE3 [2]
92
-
-
A6
Input-
Synchronous
Chip Enable 3 Input, active LOW. Sampled on
the rising edge of CLK. Used in conjunction with
CE1 and CE2 to select/deselect the device. Not
available for AJ package version. Not connected
for BGA. Where referenced, CE3[2] is assumed
active throughout this document for BGA.
OE
86
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.
