DESCRIPTION

R/W#
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.
31
MODE
Input
Mode: This input selects the burst sequence. A LOW on
(LBO#)
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 Function: This pin is internally connected to the die and
will have the capacitance of an input pin. It is allowable to
leave this pin unconnected or driven by signals. Pin 84 is
reserved as an address pin for the 18Mb ZBT SRAM.
