Description
The GM71C(S)17403C/CL is the new generation dynamic RAM organized 4,194,304 words x 4 bit. GM71C(S)17403C/CL has realized higher density, higher performance and various functions by utilizing advanced CMOS process technology. The GM71C(S)17403C/CL offers Extended Data Out (EDO) Mode as a high speed access mode. Multiplexed address inputs permit the GM71C(S)17403C/CL to be packaged in a standard 300 mil 24(26) pin SOJ and a standard 300mil 24(26) pin plastic TSOP II. The package size provides high system bit densities and is compatible with widely available automated testing and insertion equipment. System oriented features include single power supply 5V+/-10% tolerance, direct interfacing capability with high performance logic families such as Schottky TTL.
