VG26VS17400E

VIS Description or 3.3V only power supply. Low voltage operation is more suitable to be used on battery VG26(V)(S)17400E 4,194,304 x 4 - Bit CMOS Dynamic RAM The device is CMOS Dynamic RAM organized as 4,194,304 words x 4 bits. It is fabricated with an advanced submicron CMOS technology and designed to operate from a single 5V only 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 26/24 - pin plastic SOJ or TSOP (II).
