IS63WV1024BLL IS64WV1024BLL 128K x 8 HIGH-SPEED CMOS STATIC RAM MAY 2012 FEATURES DESCRIPTION High-speed access time: The ISSI IS63/64WV1024BLL is a very high-speed, low power, 131,072-word by 8-bit CMOS static RAM. The 12 ns: 3.3V + 10% IS63/64WV1024BLL is fabricated using ISSI s 15 ns: 2.5V 3.6V high-performance CMOS technology. This highly reliable High-performance, low-power CMOS process process coupled with innovative circuit design CMOS Low Power Operation techniques, yields higher performance and low power 50 mW (typical) operating current consumption devices. 25 W (typical) standby current When CE is HIGH (deselected), the device assumes a Multiple center power and ground pins for standby mode at which the power dissipation can be greater noise immunity reduced down to 25 W (typical) with CMOS input levels. Easy memory expansion with CE and OE options The IS63/64WV1024BLL operates from a single VDD power supply. The IS63/64WV1024BLL is available in CE power-down 32-pin TSOP (Type II), 32-pin sTSOP (Type I), 48-Ball Fully static operation: no clock or refresh miniBGA (6mm x 8mm), and 32-pin SOJ (300-mil) required packages. 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 FUNCTIONAL BLOCK DIAGRAM 128K X 8 A0-A16 DECODER MEMORY ARRAY VDD GND I/O COLUMN I/O I/O0-I/O7 DATA CIRCUIT CE CONTROL OE CIRCUIT WE Copyright 2012 Integrated Silicon Solution, Inc.
