DESCRIPTION
The ISSI IS61WV5128Axx and IS61/64WV5128Bxx
are very high-speed, low power, 524,288-word by
8-bit CMOS static RAMs. The IS61WV5128Axx and
IS61/64WV5128Bxx are fabricated using ISSI's high-
performance CMOS technology. This highly reliable pro-
cess coupled with innovative circuit design techniques,
yields higher performance and low power consumption
devices.
When CE is HIGH (deselected), the device assumes
a standby mode at which the power dissipation can be
reduced down with CMOS input levels.
The IS61WV5128Axx and IS61/64WV5128Bxx operate
from a single power supply.
The IS61WV5128ALL and IS61/64WV5128BLL are avail-
able in 36-pin 400-mil SOJ, 36-pin mini BGA, and 44-pin
TSOP (Type II) packages.
The IS61WV5128ALS and IS61/64WV5128BLS are
available in 32-pinTSOP (Type I), 32-pin sTSOP (Type I),
32-pin SOP and 32-pin TSOP (Type II) packages.
