1M x 16 HIGH-SPEED ASYNCHRONOUS CMOS STATIC RAM WITH 3.3V SUPPLY
FEATURES DESCRIPTION
ISSI
APRIL 2006
®
The ISSI IS61WV102416ALL/BLL and IS64WV102416BLL • High-speed access times: are high-speed, 16M-bit static RAMs organized as 1024K 8, 10, 20 ns words by 16 bits. It is fabricated using ISSI's high-perform• High-performance, low-power CMOS process ance CMOS technology. This highly reliable process coupled • Multiple center power and ground pins for greater with innovative circuit design techniques, yields high-perfornoise immunity mance and low power consumption devices. • Easy memory expansion with CE and OE options When CE is HIGH (deselected), the device assumes a • CE power-down standby mode at which the power dissipation can be reduced down with CMOS input levels. • Fully static operation: no clock or refresh required Easy memory expansion is provided by using Chip Enable • TTL compatible inputs and outputs and Output Enable inputs, CE and OE. The active LOW • Single power supply Write Enable (WE) controls both writing and reading of the VDD 1.65V to 2.2V (IS61WV102416ALL) memory. A data byte allows Upper Byte (UB) and Lower speed = 20ns for VDD 1.65V to 2.2V Byte (LB) access. VDD 2.4V to 3.6V (IS61/64WV102416BLL) ee The device is packaged in the JEDEC standard 48-pin speed = 10ns for VDD 2.4V to 3.6V DataSh TSOP Type I and 48-pin Mini BGA (9mm x 11mm). speed = 8ns for VDD 3.3V + 5% DataSheet4U.com • Packages available: – 48-ball miniBGA (9mm x 11mm) – 48-pin TSOP (Type I) • Industrial and Automotive Temperature Support • Lead-free available • Data control for upper and lower bytes
