Address inputs used to select one of the address locations. Sampled at the rising edge of the
CLK. A
Byte write inputs, active LOW. Qualified with WE to conduct writes to the SRAM. Sampled on
the rising edge of CLK.
Write enable input, active LOW. Sampled on the rising edge of CLK if CEN is active LOW. This
signal must be asserted LOW to initiate a write sequence.
Advance/load input. Used to advance the on-chip address counter or load a new address. When
HIGH (and CEN is asserted LOW) the internal burst counter is advanced. When LOW, a new
address can be loaded into the device for an access. After being deselected, ADV/LD must be
driven LOW to load a new address.
Clock input. Used to capture all synchronous inputs to the device. CLK is qualified with CEN. CLK
is only recognized if CEN is active LOW.
Chip enable 1 input, active LOW. Sampled on the rising edge of CLK. Used in conjunction with
CE
Chip enable 2 input, active HIGH. 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
Output enable, asynchronous input, active LOW. Combined with the synchronous logic block
inside the device to control the direction of the IO pins. When LOW, the IO pins are allowed to
behave as outputs. When deasserted HIGH, IO pins are tri-stated, and act as input data pins. OE
is masked during the data portion of a write sequence, during the first clock when emerging from
a deselected state, when the device has been deselected.
Clock enable input, active LOW. When asserted LOW the Clock signal is recognized by the
SRAM. When deasserted HIGH the Clock signal is masked. While deasserting CEN does not
deselect the device, use CEN to extend the previous cycle when required.
ZZ “sleep” input. This active HIGH input 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 IO 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
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 IO lines. Functionally, these signals are identical to DQ
When tied to Gnd selects linear burst sequence. When tied to V
burst sequence.
