Description
The GS70328 is a high speed CMOS static RAM organized as 32,763 words by 8 bits. Static design eliminates the need for external clocks or timing strobes. The GS70328 operates on a single 3.3 V power supply, and all inputs and outputs are TTLcompatible. The GS70328 is available in 300 mil, 28-pin SOJ and 8 x 13.4 mm2, 28-pin TSOP Type-I packages.
