9Mb, FLOW THROUGH 'NO WAIT' STATE BUS SRAM

FEATURES

DESCRIPTION

The 9 Meg product family features high-speed, low-power

synchronousstaticRAMsdesignedtoprovideaburstable,

high-performance,'nowait'state,devicefornetworkingand

communicationsapplications.Theyareorganizedas256K

words by 36 bits and 512K words by 18 bits, fabricated

with ISSI's advanced CMOS technology.

• 100 percent bus utilization

• No wait cycles between Read and Write

• Internal self-timed write cycle

• Individual Byte Write Control

• Single Read/Write control pin

Incorporating a 'no wait' state feature, wait cycles are

eliminated when the bus switches from read to write, or

write to read. This device integrates a 2-bit burst counter,

high-speed SRAM core, and high-drive capability outputs

into a single monolithic circuit.

• Clock controlled, registered address,

data and control

• Interleaved or linear burst sequence control us-

ing MODE input

Allsynchronousinputspassthroughregistersarecontrolled

byapositive-edge-triggeredsingleclockinput.Operations

may be suspended and all synchronous inputs ignored

when Clock Enable, CKE is HIGH. In this state the internal

device will hold their previous values.

• Three chip enables for simple depth expansion

and address pipelining

• Power Down mode

• Common data inputs and data outputs

• CKE pin to enable clock and suspend operation

AllRead,WriteandDeselectcyclesareinitiatedbytheADV

input. When the ADV is HIGH the internal burst counter

is incremented. New external addresses can be loaded

when ADV is LOW.

• JEDEC 100-pin QFP, 119-ball BGA, and 165-

ball BGA packages

Write cycles are internally self-timed and are initiated

by the rising edge of the clock inputs and when WE is

LOW. Separate byte enables allow individual bytes to be

written.

• Power supply:

NLF: V^dd3.3V (± 5%), Vddq 3.3V/2.5V (± 5%)

NVF: V^dd2.5V (± 5%), Vddq 2.5V (± 5%)

NVVF: V^dd1.8V (± 5%), Vddq 1.8V (± 5%)

A burst mode pin (MODE) deﬁnes the order of the burst

sequence.WhentiedHIGH,theinterleavedburstsequence

is selected. When tied LOW, the linear burst sequence is

selected.

• JTAG Boundary Scan for BGA packages

• Industrial temperature available

• Lead-free available
