IS65C25616BL Datasheet | ISSI

FEATURES - High-speed access time: 45 ns - Low Active Power: 50 m W (typical) - Low Standby Power: 10 m W (typical) CMOS standby - TTL patible interface levels - Single 5V ± 10% power supply - Fully static operation: no clock or refresh required - Package: 44-pin TSOP (Type II) - mercial, Industrial and Automotive temper- ature ranges available - Lead-free available DESCRIPTION The ISSI IS62C25616BL and IS65C25616BL are high- speed, 4,194,304-bit static RAMs organized as 262,144 words by 16 bits. They are fabricated using ISSI's high- performance CMOS technology.This highly reliable process coupled with innovative circuit design techniques, yields access times as fast as 12 ns with low power consumption. 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 IS62C25616BL and IS65C25616BL are packaged in the JEDEC standard 44-pin TSOP (Type II).
