GM71VS17803CL
2,097,152 WORDS x 8 BIT
CMOS DYNAMIC RAM
Description
The GM71V(S)17803C/CL is the new
generation dynamic RAM organized 2,097,152
x 8 bit. GM71V(S)17803C/CL has realized
higher density, higher performance and various
functions by utilizing advanced CMOS process
technology. The GM71V(S)17803C/CL offers
Extended Data out(EDO) Page Mode as a high
speed access mode. Multiplexed address inputs
permit the GM71V(S)17803C/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
* Extended Data Out Mode Capability
* Single Power Supply (3.3V+/-0.3V)
* Fast Access Time & Cycle Time
