85 85 ADSC Input-
Synchronous
Address Strobe from Controller, sampled on the ris-
ing edge of CLK. When asserted LOW, A
[x:0]
is cap-
tured in the address registers. A
[1:0]
are also loaded
into the burst counter. When ADSP
and ADSC are
both asserted, only ADSP
is recognized.
31 31 MODE Input-
Static
Selects Burst Order. When tied to GND selects lin-
ear burst sequence. When tied to V
DDQ
or left float-
ing selects interleaved burst sequence. This is a
strap pin and should remain static during device
operation.
64 64 ZZ Input-
Asynchronous
ZZ sleep Input. This active HIGH input places the
device in a non-time critical sleep condition with
data integrity preserved.

I/O-
Synchronous
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 location specified by A
during the previous clock rise of the read cycle. The
direction of the pins is controlled by OE
. When OE
is asserted LOW, the pins behave as outputs.
When HIGH, DQ
a
and DP
a
are placed in a
three-state condition.
