Features

Description

◆

Ideal for high-performance processor secondary cache

Commercial (0°C to +70°C) and Industrial (–40°C to +85°C)

Fast access times:

TheIDT71V256SAhasoutstandinglowpowercharacteristicswhile

at the same time maintaining very high performance. Address access

times of as fast as 10ns are ideal for 3.3V secondary cache in 3.3V

desktopdesigns.
