DESCRIPTION
Input
Read/Write: This input determines the cycle type when
ADV/LD# is LOW and 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.

No Connect/Data Bits: On the x32 version, these pins are
no connect (NC) and can be left floating or connected to
GND to minimize thermal impedance. On the x36 version,
these bits are DQs.
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.
LBO# is the JEDEC-standard term for MODE.
No Connect: These pins can be left floating or connected
to GND to minimize thermal impedance.

No Function: These are internally connected to the die and
will have the capacitance of input pins. It is allowable to
leave these pins unconnected or driven by signals.
Reserved for address expansion, pin 83 becomes an SA at
8Mb density and pin 84 becomes an SA at 16Mb density.
Do Not Use: These signals may either be unconnected or
wired to GND to minimize thermal impedance.
Power Supply:
See DC Electrical Characteristics and
Operating Conditions for range.
Isolated Output Buffer Supply:
See DC Electrical
Characteristics and Operating Conditions for range.
Ground:
GND.
