DESCRIPTION
The
ISSI
IS61(64)LF12832A,
IS61(64)LF/VF12836A and IS61(64)LF/VF25618A are
high-speed, low-power synchronous static
RAMs
designed
to provide burstable,
high-performance
memory for commu-
nication
and
networking
IS61(64)LF12832A is organized as 131,072 words by 32
bits. The IS61(64)LF/VF12836A is organized as 131,072
words by 36 bits. The IS61(64)LF/VF25618A is organized
as 262,144 words by 18 bits. Fabricated with
ISSI
's
advanced CMOS technology, the device integrates a 2-bit
burst counter, high-speed SRAM core, and high-drive
capability outputs into a single monolithic circuit. All syn-
chronous inputs pass through registers controlled by a
positive-edge-triggered single clock input.
IS64VF12832A,
applications.
The
Write cycles are internally self-timed and are initiated by
the rising edge of the clock input. Write cycles can be one
to four bytes wide as controlled by the write control inputs.
Separate byte enables allow individual bytes to be written.
Byte write operation is performed by using byte write
enable (
BWE
) input combined with one or more individual
byte write signals (
BWx
). In addition, Global Write (
GW
) is
available for writing all bytes at one time, regardless of the
byte write controls.
Bursts can be initiated with either
ADSP
(Address Status
Processor) or
ADSC
(Address Status Cache Controller)
input pins. Subsequent burst addresses can be generated
internally and controlled by the
ADV
(burst address ad-
vance) input pin.
The mode pin is used to select the burst sequence order,
Linear burst is achieved when this pin is tied LOW.
Interleave burst is achieved when this pin is tied HIGH or
left floating.
