IS62/65WV1288FALL IS62/65WV1288FBLL MARCH 2018 128Kx8 LOW VOLTAGE, ULTRA LOW POWER CMOS STATIC RAM KEY FEATURES DESCRIPTION High-speed access time: 45ns, 55ns The ISSI IS62/65WV1288FALL/BLL are high-speed, 1M bit static RAMs organized as 128K words by 8 bits. CMOS low power operation It is fabricated using ISSI s high-performance CMOS Operating Current: 26mA (max) at 125C technology. This highly reliable process coupled with innovative circuit design techniques, yields high- CMOS Standby Current: 3.0 uA (typ) at 25C performance and low power consumption devices. TTL compatible interface levels When CS1 is HIGH (deselected) or when CS2 is Single power supply LOW (deselected), the device assumes a standby mode at which the power dissipation can be reduced 1.65V-2.2V VDD (IS62/65WV1288FALL) down with CMOS input levels. 2.2V-3.6V VDD (IS62/65WV1288FBLL) Easy memory expansion is provided by using Chip Three state outputs Enable and Output Enable inputs. The active LOW Write Enable (WE ) controls both writing and reading Industrial and Automotive temperature support of the memory. Lead-free available The IS62/65WV1288FALL/BLL are packaged in the JEDEC standard 32-pin TSOP (TYPE I), sTSOP (TYPE I), SOP, and 36-pin mini BGA.
