GM71V17800C

GM71VS17800CL

2,097,152 WORDS x 8 BIT

CMOS DYNAMIC RAM

Description

The GM71V(S)17800C/CL is the new

generation dynamic RAM organized 2,097,152

x 8 bit. GM71V(S)17800C/CL has realized

higher density, higher performance and various

functions by utilizing advanced CMOS process

technology. The GM71V(S)17800C/CL offers

Fast Page Mode as a high speed access mode.

Multiplexed address inputs permit the

GM71V(S)17800C/CL to be packaged in

standard 400 mil 28pin plastic SOJ, and

standard 400mil 28pin plastic TSOP II. The

package size provides high system bit densities

and is compatible with widely available

automated testing and insertion equipment.

Features

* 2,097,152 Words x 8 Bit Organization

* Fast Page Mode Capability

* Single Power Supply (3.3V+/-0.3V)

* Fast Access Time & Cycle Time
