IS62WV5128BLL-55T2I ISSI

IS62WV5128ALL IS62WV5128BLL 512K x 8 LOW VOLTAGE, JANUARY 2008 ULTRA LOW POWER CMOS STATIC RAM FEATURES DESCRIPTION The ISSI IS62WV5128ALL / IS62WV5128BLL are high- High-speed access time: 55ns, 70ns speed, 4M bit static RAMs organized as 512K words by 8 CMOS low power operation bits. It is fabricated using ISSI s high-performance CMOS technology. This highly reliable process coupled with 36 mW (typical) operating innovative circuit design techniques, yields high- 9 W (typical) CMOS standby performance and low power consumption devices. TTL compatible interface levels When CS1 is HIGH (deselected) the device assumes a standby mode at which the power dissipation can be Single power supply reduced down with CMOS input levels. 1.65V 2.2V VDD (IS62WV5128ALL) Easy memory expansion is provided by using Chip Enable and Output Enable inputs. The active LOW Write Enable 2.5V 3.6V VDD (IS62WV5128BLL) (WE) controls both writing and reading of the memory. Fully static operation: no clock or refresh The IS62WV5128ALL and IS62WV5128BLL are packaged required in the JEDEC standard 32-pin TSOP (TYPE I), 32-pin sTSOP (TYPE I), 32-pin TSOP (Type II), 32-pin SOP and Three state outputs 36-pin mini BGA.
