Commercial Temp

Industrial Temp

1.8 V V

1.8 V and 1.5 V I/O

are just one element in a family of low power, low voltage

HSTL I/O SRAMs designed to operate at the speeds needed to

implement economical high performance networking systems.

Features

• 2.0 clock Latency

• Simultaneous Read and Write SigmaQuad™ Interface

• JEDEC-standard pinout and package

• Dual Double Data Rate interface

• Byte Write controls sampled at data-in time

• Dual-Range On-Die Termination (ODT) on Data (D), Byte

Write (BW), and Clock (K, K) inputs

• Burst of 2 Read and Write

• 1.8 V +100/–100 mV core power supply

• 1.5 V or 1.8 V HSTL Interface

Clocking and Addressing Schemes

The GS81302QT07/10/19/37E SigmaQuad-II+ SRAMs are

synchronous devices. They employ two input register clock

inputs, K and K. K and K are independent single-ended clock

inputs, not differential inputs to a single differential clock input

buffer.

• Pipelined read operation

• Fully coherent read and write pipelines

• ZQ pin for programmable output drive strength

• Data Valid Pin (QVLD) Support

• IEEE 1149.1 JTAG-compliant Boundary Scan

• 165-bump, 15 mm x 17 mm, 1 mm bump pitch BGA package

• RoHS-compliant 165-bump BGA package available

Each internal read and write operation in a SigmaQuad-II+ B2

RAM is two times wider than the device I/O bus. An input data

bus de-multiplexer is used to accumulate incoming data before

it is simultaneously written to the memory array. An output

data multiplexer is used to capture the data produced from a

single memory array read and then route it to the appropriate

output drivers as needed. Therefore the address field of a

SigmaQuad-II+ B2 RAM is always one address pin less than

the advertised index depth (e.g., the 16M x 8 has an 8M

addressable index).

SigmaQuad™ Family Overview

The GS81302QT07/10/19/37E are built in compliance with

the SigmaQuad-II+ SRAM pinout standard for Separate I/O

synchronous SRAMs. They are 150,994,944-bit (144Mb)

SRAMs. The GS81302QT07/10/19/37E SigmaQuad SRAMs
