IS61WV51216EEALL IS61/64WV51216EEBLL AUGUST 2019 512Kx16 HIGH SPEED AYNCHRONOUS CMOS STATIC RAM with ECC KEY FEATURES DESCRIPTION High-speed access time: 8ns, 10ns, 20ns The ISSI IS61/64WV51216EEALL/BLL are high-speed, low Single power supply 1.65V-2.2V VDD (IS61WV51216EEALL) power, 8M bit static RAMs organized as 512K words by 16 2.4V-3.6V VDD (IS61/64WV51216EEBLL) bits. It is fabricated using ISSI s high-performance CMOS Error Detection and Correction with optional technology and implemented ECC function to improve ERR1/ERR2 output pin: reliability. - ERR1 pin indicates 1-bit error detection and correction. This highly reliable process coupled with innovative circuit - ERR2 pin indicates 2-bit error detection design techniques including ECC (SEC-DED: Single Error Package Available: Correcting-Double Error Detecting) yield high-performance - 44-pin TSOP (Type II) and highly reliable devices. - 48-pin TSOP (Type I) - 48-ball mini BGA (6mm x 8mm) When CS is HIGH (deselected), the device assumes a - 54 pin TSOP (Type II) standby mode at which the power dissipation can be Three state outputs reduced down with CMOS input levels. Industrial and Automotive temperature support Easy memory expansion is provided by using Chip Enable Lead-free available and Output Enable inputs. The active LOW Write Enable (WE ) controls both writing and reading of the memory. FUNCTIONAL BLOCK DIAGRAM A data byte allows Upper Byte (UB ) and Lower Byte (LB ) Memory Memory access.
