SINGLE-CYCLE DESELECT STATIC RAM

DESCRIPTION

FEATURES

The ISSI IS61LPS25632T/D/J,IS61LPS25636T/D/J,and

IS61LPS51218T/D/J are high-speed, low-power synchro-

nous static RAMs designed to provide burstable, high-

performance memory for communication and networking

applications. The IS61LPS25632T/D/J is organized as

262,144 words by 32 bits and the IS61LPS25636T/D/J is

organizedas262,144wordsby36bits.TheIS61LPS51218T/

D/J is organized as 524,288 words by 18 bits. Fabricated

with ISSI's advanced CMOS technology, the device inte-

grates a 2-bit burst counter, high-speed SRAM core, and

high-drivecapabilityoutputsintoasinglemonolithiccircuit.

Allsynchronousinputspassthroughregisterscontrolledby

a positive-edge-triggered single clock input.

• Internal self-timed write cycle

• Individual Byte Write Control and Global Write

• Clock controlled, registered address, data and

control

• Linear burst sequence control using MODE

input

•

Three chip enable option for simple depth

expansion and address pipelining

• Common data inputs and data outputs

• JEDEC 100-Pin TQFP and

119-pin PBGA package

Writecyclesareinternallyself-timedandareinitiatedbythe

risingedgeoftheclockinput.Writecyclescanbeonetofour

bytes wide as controlled by the write control inputs.

• Power Supply

+3.3V V^DD

Separate byte enables allow individual bytes to be written.

Bytewriteoperationisperformedbyusingbytewriteenable

(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.

+3.3V or 2.5 VDDQ (I/O)

• Auto Power-down during deselect

• Single cycle deselect

• Snooze MODE for reduced-power standby

• JTAG Boundary Scan for PBGA package

• T Version (three chips selects)

• D Version (two chips selects)

• J Version (PBGA Package with JTAG)

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. Inter-

leave burst is achieved when this pin is tied HIGH or left

floating.
