IS61/64WV5128FALL IS61/64WV5128FBLL APRIL 2018 512Kx8 HIGH SPEED AYNCHRONOUS CMOS STATIC RAM KEY FEATURES DESCRIPTION High-speed access time: 8, 10ns, 12ns The ISSI IS61/64WV5128FALL/FBLL are high-speed, low Low Active Current: 35mA (Max., 10ns, I-temp) power, 4M bit static RAMs organized as 512K words by 8 Low Standby Current: 10 mA (Max., I-temp) ISSI bits. It is fabricated using s high-performance CMOS technology. Single power supply 1.65V-2.2V VDD(IS61/64WV5128FALL) This highly reliable process coupled with innovative circuit 2.4V-3.6V VDD (IS61/64WV5128FBLL) design techniques, yields high-performance and low power Three state outputs devices. Industrial and Automotive temperature support When CS is HIGH (deselected), the device assumes a standby mode at which the power dissipation can be Lead-free available reduced down with CMOS input levels. FUNCTIONAL BLOCK DIAGRAM Easy memory expansion is provided by using Chip Enable and Output Enable inputs. The active LOW Write Enable (WE ) controls both writing and reading of the memory. 512K x 8 MEMORY DECODER A0 A18 ARRAY The IS61/64WV5128FALL/FBLL are packaged in the JEDEC standard 44-pin TSOP (TYPE II), 36-pin SOJ and 36-ball VDD mini BGA (6mm x 8mm).
