FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION
The ISSI IS61WV10248ALL/BLL and IS64WV10248BLL
are very high-speed, low power, 1M-word by 8-bit CMOS
static RAM. The IS61WV10248ALL/BLL and
IS64WV10248BLL are fabricated using ISSI's high-
performance CMOS technology. This highly reliable
process coupled with innovative circuit design tech-
niques, yields higher performance and low power con-
sumption 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 IS61WV10248ALL/BLL and IS64WV10248BLL
operate from a single power supply and all inputs are
TTL-compatible.
The IS61WV10248ALL/BLL and IS64WV10248BLL are
available in 48 ball mini BGA and 44-pin TSOP (Type II)
packages.
