DESCRIPTION
The
1M-word by 8-bit CMOS static RAM. The IS61LV10248 is
fabricated using
ogy. 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 IS61LV10248 operates from a single 3.3V power
supply and all inputs are TTL-compatible.
The IS61LV10248 is available in 48 ball mini BGA, 36-ball
mini BGA, and 44-pin TSOP (Type II) packages.
