ISSI IS64LV25616AL 256K x 16 HIGH SPEED ASYNCHRONOUS CMOS STATIC RAM WITH 3.3V SUPPLY FEATURES ® JULY 2006 DESCRIPTION The ISSI IS64LV25616AL is a high-speed, 4,194,304-bit • High-speed access time: 10, 12 ns • CMOS low power operation • Low stand-by power: Less than 5 mA (typ.) CMOS stand-by • TTL compatible interface levels • Single 3.3V power supply • Fully static operation: no clock or refresh required • Three state outputs • Data control for upper and lower bytes • Industrial temperature available • Temperature Offerings: Option A1: –40oC to +85oC Option A2: –40oC to +105oC Option A3: –40oC to +125oC • Lead-free available static RAM organized as 262,144 words by 16 bits. It is fabricated using ISSI's high-performance CMOS technology. This highly reliable process coupled with innovative circuit design techniques, yields high-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 with CMOS input levels. Easy memory expansion is provided by using Chip Enable and Output Enable inputs, CE and OE. The active LOW Write Enable (WE) controls both writing and reading of the memory. A data byte allows Upper Byte (UB) and Lower Byte (LB) access. The IS64LV25616AL is packaged in the JEDEC standard 44-pin TSOP Type II and 48-pin Mini BGA (8mm x 10mm).
