DESCRIPTION

FEATURES

The ISSI IS61WV25616Axx/Bxx and IS64WV25616Bxx

are high-speed, 4,194,304-bit static RAMs organized as

262,144 words by 16 bits. It is fabricated usingISSI's high-

performance CMOS technology. This highly reliable pro-

cess coupled with innovative circuit design techniques,

yields high-performance and low power consumption de-

vices.

HIGHSPEED:(IS61/64WV25616ALL/BLL)

• High-speed access time: 8, 10, 20 ns

• Low Active Power: 85 mW (typical)

• Low Standby Power: 7 mW (typical)

CMOS standby

LOWPOWER:(IS61/64WV25616ALS/BLS)

• High-speed access time: 25, 35, 45 ns

• Low Active Power: 35 mW (typical)

When CE is HIGH (deselected), the device assumes a

standby mode at which the power dissipation can be

reduced down with CMOS input levels.

• Low Standby Power: 0.6 mW (typical)

CMOS standby

Easy memory expansion is provided by using Chip Enable

and Output Enable inputs, CE and OE. The active LOW

Write Enable (WE) controls both writing and reading of the

memory. A data byte allows Upper Byte (UB) and Lower

Byte (LB) access.

• Singlepowersupply

— VDD 1.65V to 2.2V (IS61WV25616Axx)

— VDD 2.4V to 3.6V (IS61/64WV25616Bxx)

• Fully static operation: no clock or refresh required

• Three state outputs

The IS61WV25616Axx/Bxx and IS64WV25616Bxx are

packagedintheJEDECstandard44-pinTSOPTypeII and

48-pin Mini BGA (6mm x 8mm).

• Data control for upper and lower bytes

• IndustrialandAutomotivetemperaturesupport

• Lead-freeavailable
