IS62WV102416ALL IS62WV102416BLL IS65WV102416BLL 1M x 16 HIGH-SPEED LOW POWER ASYNCHRONOUS CMOS STATIC RAM APRIL 2015 FEATURES DESCRIPTION High-speed access times: The ISSI IS62WV102416ALL/BLL and IS65WV102416BLL 25, 35 ns are high -speed, 16M-bit static RAMs organized as 1024K words by 16 bits. It is fabricated using ISSI s high-perfor - High-performance, low-power CMOS process mance CMOS technology. This highly reliable process Multiple center power and ground pins for greater coupled with innovative circuit design techniques, yields noise immunity high-performance and low power consumption devices. Easy memory expansion with CS1 and OE options When CS1 is HIGH (deselected) or when CS2 is LOW CS1 power-down (deselected) or when CS1 is LOW, CS2 is HIGH and both Fully static operation: no clock or refresh LB and UB are HIGH, the device assumes a standby mode required at which the power dissipation can be reduced down with TTL compatible inputs and outputs CMOS input levels. Single power supply Easy memory expansion is provided by using Chip Enable Vdd 1.65V to 2.2V (IS62WV102416ALL) and Output Enable inputs. The active LOW Write Enable speed = 35ns for Vdd 1.65V to 2.2V (WE) controls both writing and reading of the memory. A Vdd 2.4V to 3.6V (IS62/65WV102416BLL) data byte allows Upper Byte (UB) and Lower Byte (LB) speed = 25ns for Vdd 2.4V to 3.6V access. Packages available: 48-ball miniBGA (9mm x 11mm) The device is packaged in the JEDEC standard 48-pin 48-pin TSOP (Type I) TSOP Type I and 48-pin Mini BGA (9mm x 11mm).
