Description

The device is CMOS Dynamic RAM organized as 1,048,576 words x 16 bits. It is fabri-cated with an advanced submicron CMOS technology and designed to operate from a single 5V only or 3.3V only power supply. Low voltage operation is more suitable to be used on battery backup, portable electronic application. A new refresh feature called " self-refresh " is supported and very slow CBR cycles are being performed. It is packaged in JEDEC standard 42 - pin plastic SOJ.
