IS61WV5128ALL/ALS IS61WV5128BLL/BLS IS64WV5128BLL/BLS 512K x 8 HIGH-SPEED ASYNCHRONOUS CMOS STATIC RAM AUGUST 2009 FEATURES DESCRIPTION HIGH SPEED: (IS61/64WV5128ALL/BLL) The ISSI IS61WV5128Axx and IS61/64WV5128Bxx are very high-speed, low power, 524,288-word by High-speed access time: 8, 10, 20 ns 8-bit CMOS static RAMs. The IS61WV5128Axx and Low Active Power : 85 mW (typical) IS61/64WV5128Bxx are fabricated using ISSI s high- Low stand-by power : 7 mW (typical) performance CMOS technology. This highly reliable pro- CMOS standby cess coupled with innovative circuit design techniques, yields higher performance and low power consumption LOW POWER: (IS61/64WV5128ALS/BLS) devices. High-speed access time: 25, 35 ns When CE is HIGH (deselected), the device assumes Low Active Power : 35 mW (typical) a standby mode at which the power dissipation can be Low stand-by power : 0.6 mW (typical) reduced down with CMOS input levels. CMOS standby The IS61WV5128Axx and IS61/64WV5128Bxx operate Single power supply from a single power supply. Vdd 1.65V to 2.2V (IS61WV5128Axx) The IS61WV5128ALL and IS61/64WV5128BLL are avail- Vdd 2.4V to 3.6V (IS61/64WV5128Bxx) able in 36-pin 400-mil SOJ, 36-pin mini BGA, and 44-pin TSOP (Type II) packages. Fully static operation: no clock or refresh required The IS61WV5128ALS and IS61/64WV5128BLS are available in 32-pinTSOP (Type I), 32-pin sTSOP (Type I), Three state outputs 32-pin SOP and 32-pin TSOP (Type II) packages.
