Description
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
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 26/24 - pin
plastic SOJ or TSOP (II).
Features
• Single 5V (±10 %) or 3.3V (±10 %) only power supply
• High speed tRAC access time : 50/60 ns
• Low power dissipation
- Active mode : 5V version 605/550 mW (Max.)
3.3V version 396/360 mW (Max.)
- Standby mode : 5V version 1.375 mW (Max.)
3.3V version 0.54 mW (Max.)
• Fast Page Mode access
• I/O level : TTL compatible (Vcc = 5V)
LVTTL compatible (Vcc = 3.3V)
• 2048 refresh cycles in 32 ms (Std) or 128ms (S - version)
• 4 refresh mode :
- RAS only refresh
- CAS-before-RAS refresh
- Hidden refresh
- Self - refresh (S - version)
