Description
Snooze Enable : This active high asynchronous input causes
the device to enter a low-power standby mode in which all
data in the memory array is retained. When active, all other
inputs are ignored.
Read/Write : This active input determines the cycle type
when ADV/LD is LOW. This is the only means for
determining READs and WRITEs. READ cycles may not be
converted into WRITEs (and vice versa) other than by
loading a new address. A LOW on this pin permits BYTE
WRITE operations and must meet the setup and hold times
around the rising edge of CLK. Full bus width WRITEs occur
if all byte write enables are LOW.
SRAM Data I/O : Byte “a” is I/Oa pins; Byte “b” is I/Ob pins;
Byte “c” is I/Oc pins; Byte “d” is I/Od pins. Input data must
meet setup and hold times around CLK rising edge.
Mode : This input selects the burst sequence. A LOW on this
pin selects linear burst. NC or HIGH on this pin selects
interleaved burst. Do not alter input state while device is
operating.
No Connect : These pins can be left floating or connected to
GND to minimize thermal impedance.
Power Supply : See DC Electrical Characteristics and
Operating Conditions for range.
These pins do not have to be connected directly to VCC as
long as the input voltage is ≥ VIH. This input is not connected
to VCC bus internally.
Isolated Output Buffer Supply : See DC Electrical
Characteristics and Operating Conditions for range.
Ground : GND.
