18Mb Sync Burst SRAMs

1.8 V V

1.8 V I/O

cycles can be initiated with either ADSP or ADSC inputs. In

Features

Burst mode, subsequent burst addresses are generated

internally and are controlled by ADV. The burst address

counter may be configured to count in either linear or

interleave order with the Linear Burst Order (LBO) input. The

Burst function need not be used. New addresses can be loaded

on every cycle with no degradation of chip performance.

• FT pin for user-configurable flow through or pipeline

operation

• Single Cycle Deselect (SCD) operation

• 1.8 V +10%/–10% core power supply

• 1.8 V I/O supply

• LBO pin for Linear or Interleaved Burst mode

• Internal input resistors on mode pins allow floating mode pins

• Default to Interleaved Pipeline mode

• Byte Write (BW) and/or Global Write (GW) operation

• Internal self-timed write cycle

Flow Through/Pipeline Reads

The function of the Data Output register can be controlled by

the user via the FT mode pin (Pin 14). Holding the FT mode

pin low places the RAM in Flow Through mode, causing

output data to bypass the Data Output Register. Holding FT

high places the RAM in Pipeline mode, activating the rising-

edge-triggered Data Output Register.

• Automatic power-down for portable applications

• JEDEC-standard 100-lead TQFP package

• Pb-Free 100-lead TQFP package available

Byte Write and Global Write

Functional Description

Byte write operation is performed by using Byte Write enable

(BW) input combined with one or more individual byte write

signals (Bx). In addition, Global Write (GW) is available for

writing all bytes at one time, regardless of the Byte Write

control inputs.

Applications

The GS8160V18/36CT is an 18,874,368-bit (16,777,216-bit

for x32 version) high performance synchronous SRAM with a

2-bit burst address counter. Although of a type originally

developed for Level 2 Cache applications supporting high

performance CPUs, the device now finds application in

synchronous SRAM applications, ranging from DSP main

store to networking chip set support.

Sleep Mode

Low power (Sleep mode) is attained through the assertion

(High) of the ZZ signal, or by stopping the clock (CK).

Memory data is retained during Sleep mode.

Controls

Core and Interface Voltages

Addresses, data I/Os, chip enables (E1, E2, E3), address burst

control inputs (ADSP, ADSC, ADV), and write control inputs

(Bx, BW, GW) are synchronous and are controlled by a

positive-edge-triggered clock input (CK). Output enable (G)

and power down control (ZZ) are asynchronous inputs. Burst

The GS8160V18/36CT operates on a 1.8 V power supply. All

input are 1.8 V compatible. Separate output power (V

)

DDQ

pins are used to decouple output noise from the internal circuits

and are 1.8 V compatible.
