Address Inputs used to select one of the 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
are sampled active. A
[1:0]
feed the 2-bit counter.
Byte Write Select Inputs, active LOW. Qualified with BWE to conduct byte
writes to the SRAM. Sampled on the rising edge of CLK.

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
a,b,c,d
and BWE).
Byte Write Enable Input, active LOW. Sampled on the rising edge of CLK. This
signal must be asserted LOW to conduct a byte write.
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.
Chip Enable 1 Input, active LOW. Sampled on the rising edge of CLK. Used
in conjunction with CE
2
and CE
3
to select/deselect the device. ADSP is ig-
nored if CE
1
is HIGH.
Chip Enable 2 Input, active HIGH. Sampled on the rising edge of CLK. Used
in conjunction with CE
1
and CE
3
to select/deselect the device. (TQFP Only)
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.
(TQFP Only)
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.
Advance Input signal, sampled on the rising edge of CLK. When asserted, it
automatically increments the address in a burst cycle.
Address Strobe from Processor, sampled on the rising edge of CLK. When
asserted LOW, A is captured 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. ASDP is ignored when CE
1
is deasserted HIGH.
Address Strobe from Controller, sampled on the rising edge of CLK. When
asserted LOW, A
[x:0]
is captured 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.
Selects Burst Order. When tied to GND selects linear burst sequence. When
tied to V
DDQ
or left floating selects interleaved burst sequence. This is a strap
pin and should remain static during device operation.
ZZ “sleep” Input. This active HIGH input places the device in a non-time critical
“sleep” condition with data integrity preserved.
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, DQx and DPx
are
placed in a three-state condition.
Serial data-out to the JTAG circuit. Delivers data on the negative edge of TCK
(BGA Only).
