ISSI IS63WV1024BLL IS64WV1024BLL ® 128K x 8 HIGH-SPEED CMOS STATIC RAM MAY 2006 FEATURES DESCRIPTION • High-speed access time: 12 ns: 3.3V + 10% 15 ns: 2.5V – 3.6V • High-performance, low-power CMOS process • CMOS Low Power Operation 50 mW (typical) operating current 25 µW (typical) standby current • Multiple center power and ground pins for greater noise immunity • Easy memory expansion with CE and OE options • CE power-down • Fully static operation: no clock or refresh required • TTL compatible inputs and outputs • Packages available: – 32-pin TSOP (Type II) – 32-pin sTSOP (Type I) – 48-Ball miniBGA (6mm x 8mm) – 32-pin 300-mil SOJ • Lead-free available 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.
