I/O
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
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

Sampled on the rising edge of CLK. Used in
conjunction with CE

Chip Enable 3 Input, active LOW.
Sampled on the rising edge of CLK. Used in
conjunction with CE
select/deselect the device.
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,
active LOW. When asserted LOW,
addresses presented to the device are
captured in the address registers. A
also loaded into the burst counter. When
ADSP and ADSC are both asserted, only
ADSP is recognized. ASDP is ignored when
