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
active. A
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
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

Chip Enable 3 Input, active LOW. Sampled on the rising edge of CLK. Used in
conjunction with CE
new external address is loaded.
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
tristated, 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 automat-
ically 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
asserted, only ADSP is recognized. ASDP is ignored when CE
Address Strobe from Controller, sampled on the rising edge of CLK, active LOW.
When asserted LOW, addresses presented to the device are captured in the address
registers. A
asserted, only ADSP is recognized.
Byte Write Enable Input, active LOW. Sampled on the rising edge of CLK. This signal
must be asserted LOW to conduct a byte write.
ZZ “sleep” Input, active HIGH. When asserted HIGH places the device in a
non-time-critical “sleep” condition with data integrity preserved. For normal operation, this
pin has to be LOW or left floating. ZZ pin has an internal pull down.
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 the addresses presented 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
condition.The outputs are automatically tristated during the data portion of a write
sequence, during the first clock when emerging from a deselected state, and when the
device is deselected, regardless of the state of OE.
Bidirectional Data Parity I/O Lines. Functionally, these signals are identical to DQ
During write sequences, DQP
Selects Burst Order. When tied to GND selects linear burst sequence. When tied to V
or left floating selects interleaved burst sequence. This is a strap pin and should remain
static during device operation. Mode Pin has an internal pull up.
