DESCRIPTION

FEATURES

The ISSI IS61(64)LF12832A,

IS64VF12832A,

• Internal self-timed write cycle

• Individual Byte Write Control and Global Write

IS61(64)LF/VF12836A and IS61(64)LF/VF25618A are

high-speed, low-powersynchronousstaticRAMs designed

to provide burstable, high-performance memory for commu-

nication and networking applications. The

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.

• Clock controlled, registered address, data and

control

• Burst sequence control using MODE input

•

Three chip enable option for simple depth expan-

sion and address pipelining

• Common data inputs and data outputs

• Auto Power-down during deselect

• Single cycle deselect

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.

• Snooze MODE for reduced-power standby

• Power Supply

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.

LF: V^DD3.3V + 5%, VDDQ 3.3V/2.5V + 5%

VF: V^DD2.5V -5% +10%, VDDQ 2.5V -5% +10%

• JEDEC 100-Pin TQFP, 119-pin PBGA, and

165-pin PBGA packages

• Automotive temperature available

• Lead-free available

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.
