GM71C17803C

GM71CS17803CL

2,097,152 WORDS x 8 BIT

CMOS DYNAMIC RAM

Description

The GM71C(S)17803C/CL is the new

generation dynamic RAM organized 2,097,152

x 8 bit. GM71C(S)17803C/CL has realized

higher density, higher performance and various

functions by utilizing advanced CMOS process

technology. The GM71C(S)17803C/CL offers

Extended Data out(EDO) Page Mode as a high

speed access mode. Multiplexed address inputs

permit the GM71C(S)17803C/CL to be

packaged in standard 400 mil 28 pin 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

* Extended Data Out Mode Capability

* Single Power Supply (5V+/-10%)

* Fast Access Time & Cycle Time
