DESCRIPTION
The ISSI IS61WV20488ALL/BLL and
IS64WV20488BLL are very high-speed, low
power, 2M-word by 8-bit CMOS static RAM. The
IS61WV20488ALL/BLL and IS64WV20488BLL are fabricated using ISSI's high-performance CMOS technology. This highly reliable process 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 IS61WV20488ALL/BLL and IS64WV20488BLL
operate from a single power supply and all inputs are
TTL-compatible.
The IS61WV20488ALL/BLL and IS64WV20488BLL are
available in 48 ball mini BGA and 44-pin TSOP (Type II)
packages.
