IS62WV1288ALL IS62WV1288BLL, IS65WV1288BLL DECEMBER 2008 128K x 8 LOW VOLTAGE, ULTRA LOW POWER CMOS STATIC RAM FEATURES DESCRIPTION The ISSI IS62WV1288ALL / IS62/65WV1288BLL are High-speed access time: 45ns, 55ns, 70ns high-speed, 1M bit static RAMs organized as 128K words CMOS low power operation: by 8 bits. It is fabricated using ISSI s high-performance CMOS technology. This highly reliable process coupled 30 mW (typical) operating with innovative circuit design techniques, yields high- 15 W (typical) CMOS standby performance and low power consumption devices. TTL compatible interface levels When CS1 is HIGH (deselected) or when CS2 is LOW (deselected), the device assumes a standby mode at Single power supply: which the power dissipation can be reduced down with CMOS input levels. 1.65V--2.2V Vdd (62WV1288ALL) Easy memory expansion is provided by using Chip Enable 2.5V--3.6V Vdd (62WV1288BLL/ 65WV1288BLL) and Output Enable inputs. The active LOW Wr ite Enable Fully static operation: no clock or refresh (WE) controls both writing and reading of the memory. required T h e I S 6 2 W V 1 2 8 8 A L L a n d I S 6 2 / 6 5 W V 1 2 8 8 B L L a r e packaged in the JEDEC standard 32-pin TSOP (TYPEI), Three state outputs sTSOP (TYPEI), SOP, and 36-pin mini BGA.
