DESCRIPTION
The ISSI IS63/64WV1024BLL is a very high-speed, low
power, 131,072-word by 8-bit CMOS static RAM. The
IS63/64WV1024BLL is 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 to 25 µW (typical) with CMOS input levels.
The IS63/64WV1024BLL operates from a single VDD
power supply. The IS63/64WV1024BLL is available in
32-pin TSOP (Type II), 32-pin sTSOP (Type I), 48-Ball
miniBGA (6mm x 8mm), and 32-pin SOJ (300-mil)
packages.
