IS62WV12816DALL/DBLL IS65WV12816DALL/DBLL JUNE2013 128Kx 16LO W VOLTAGE, ULTRALO WPO WERCMOSSTATICRAM FEATURES DESCRIPTION The ISSI IS62/65WV12816DALL/DBLL are high-speed, High-speed access time: 35ns, 45ns, 55ns 2M bit static RAMs organized as 128K words by 16 CMOS low power operation bits. It is fabricated using I S S I s high-performance 36 mW (typical) operating CMOS technology. This highly reliable process coupled 9 W (typical) CMOS standby with innovative circuit design techniques, yields high- TTL compatible interface levels performance and low power consumption devices. Single power supply When CS1 is HIGH (deselected) or when CS2 is LOW 1.8V 10%Vdd (IS62/65WV12816d ALL) (deselected) or when CS1 is LOW, CS2 is HIGH and both 2.5V--3.6VV dd (IS62/65WV12816dBLL) LB and UB are HIGH, the device assumes a standby mode Fully static operation: no clock or refresh at which the power dissipation can be reduced down with CMOS input levels. required Three state outputs Easy memory expansion is provided by using Chip Enable and Output Enable inputs. The active LOW Write Enable Data control for upper and lower bytes (WE) controls both writing and reading of the memory. A Industrial and Autotmovie temperature support data byte allows Upper Byte (UB) and Lower Byte (LB) 2CS Option Available access. Lead-free available The IS62/65WV12816DALL/DBLL are packaged in the JEDEC standard 48-pin mini BGA (6mm x 8mm) and 44- Pin TSOP (TYPE II).
