Synchronous Address Inputs: These inputs are registered and must

meet the setup and hold times around the rising edge of CLK.

BWa#
Input
Synchronous Byte Write Enables: These active LOW inputs allow
94
BWb#
individual bytes to be written and must meet the setup and hold
–
95
BWc#
times around the rising edge of CLK. A byte write enable is LOW
–
96
BWd#
for a WRITE cycle and HIGH for a READ cycle. For the x18 version,
BWa# controls DQa pins and DQPa; BWb# controls DQb pins and
DQPb. For the x32 and x36 versions, BWa# controls DQa pins and
DQPa; BWb# controls DQb pins and DQPb; BWc# controls DQc pins
and DQPc; BWd# controls DQd pins and DQPd. Parity is only
available on the x18 and x36 versions.
87
BWE#
Input
Byte Write Enable: This active LOW input permits BYTE WRITE
operations and must meet the setup and hold times around the
rising edge of CLK.
88
GW#
Input
Global Write: This active LOW input allows a full 18-, 32-, or 36-bit
WRITE to occur independent of the BWE# and BWx# lines and must
meet the setup and hold times around the rising edge of CLK.
89
CLK
Input
Clock: This signal registers the address, data, chip enable, byte write
enables, and burst control inputs on its rising edge. All synchronous
inputs must meet setup and hold times around the clock’s rising
edge.
98
CE#
Input
Synchronous Chip Enable: This active LOW input is used to enable
the device and conditions the internal use of ADSP#. CE# is sampled
only when a new external address is loaded.
92
CE2#
Input
Synchronous Chip Enable: This active LOW input is used to enable
the device and is sampled only when a new external address is
loaded.
97
CE2
Input
Synchronous Chip Enable: This active HIGH input is used to enable
the device and is sampled only when a new external address is
loaded.
86
OE#
Input
Output Enable: This active LOW, asynchronous input enables the
data I/O output drivers.
83
ADV#
Input
Synchronous Address Advance: This active LOW input is used to
advance the internal burst counter, controlling burst access after the
external address is loaded. A HIGH on this pin effectively causes wait
states to be generated (no address advance). To ensure use of
correct address during a WRITE cycle, ADV# must be HIGH at the
rising edge of the first clock after an ADSP# cycle is initiated.
84
ADSP#
Input
Synchronous Address Status Processor: This active LOW input
interrupts any ongoing burst, causing a new external address to be
registered. A READ is performed using the new address,
independent of the byte write enables and ADSC#, but dependent
upon CE#, CE2 and CE2#. ADSP# is ignored if CE# is HIGH. Power-
down state is entered if CE2 is LOW or CE2# is HIGH.
