IS66WV1M16DALL IS66WV1M16DBLL PRELIMINARYINFORMATION MARCH2011 16MbLOW VOLTAGE, ULTRALO WPOWERPSEUDO CMOS STATICRAM FEATURES DESCRIPTION High-speed access time: The I S S I IS66WV1M16DALL/DBLL is a high-speed, 70ns (IS66WV1M16DALL/DBLL) 16M bit static RAMs organized as 1Mb words by 16 55ns (IS66WV1M16DBLL) bits. It is fabricated using I S S I s high-performance CMOS technology. This highly reliable process coupled CMOS low power operation with innovative circuit design techniques, yields high- Single power supply performance and low power consumption devices. Vdd = 1.7V - 1.95V (IS66WV1M16d ALL) When CS1 is HIGH (deselected) or when CS2 is LOW Vdd = 2.5V - 3.6V (IS66WV1M16BLL)d (deselected) or when CS1 is LOW, CS2 is HIGH and both LB and UB are HIGH, the device assumes a standby mode Three state outputs at which the power dissipation can be reduced down with Data control for upper and lower bytes CMOS input levels. Industrial temperature available Easy memory expansion is provided by using Chip Enable Lead-free available and Output Enable inputs. 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 IS66WV1M16DALL/DBLL is packaged in the JEDEC standard 48-ball mini BGA (6mm x 8mm). The device is also available for die sales.
