DESCRIPTION

FEATURES

The ISSI IS61LPD/VPD51236A and IS61LPD/

VPD102418Aarehigh-speed,low-powersynchronousstatic

RAMsdesignedtoprovideburstable,high-performancememory

for communication and networking applications. The

IS61LPD/VPD51236Aisorganizedas524,288wordsby36

bits, and the IS61LPD/VPD102418A is organized as

1,048,576 words by 18 bits. Fabricated with ISSI's ad-

vanced CMOS technology, the device integrates a 2-bit

burstcounter,high-speedSRAMcore,andhigh-drivecapa-

bility outputs into a single monolithic circuit. All synchro-

nousinputspassthroughregisterscontrolledbyapositive-

edge-triggeredsingleclockinput.

• Internal self-timed write cycle

• Individual Byte Write Control and Global Write

• Clock controlled, registered address, data and

control

• Burst sequence control using MODE input

• Three chip enable option for simple depth

expansion and address pipelining

• Common data inputs and data outputs

• Auto Power-down during deselect

• Double cycle deselect

Writecyclesareinternallyself-timedandareinitiatedbythe

risingedgeoftheclockinput.Writecyclescanbeonetofour

bytes wide as controlled by the write control inputs.

• Snooze MODE for reduced-power standby

• JTAG Boundary Scan for PBGA package

• Power Supply

Separate byte enables allow individual bytes to be written.

The byte write operation is performed by using the 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.

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

VPD: V^DD2.5V + 5%, VDDQ 2.5V + 5%

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

advance) input pin.

• JEDEC 100-Pin TQFP and 165-pin PBGA

package

• Lead-free available

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.
