IS61WV51216EDALL IS61/64WV51216EDBLL 512K x 16 HIGH-SPEED ASYNCHRONOUS FEBRUARY 2013 CMOS STATIC RAM WITH ECC FEATURES DESCRIPTION High-speed access times: 8, 10, 20 ns The ISSI IS61WV51216EDALL and IS61/64WV51216EDBLL are high-speed, 8M-bit static High-perfor mance, low-power CMOS process RAMs organized as 512K words by 16 bits. It is fabr i- Multiple center power and ground pins for greater cated using ISSI s high-perfor mance CMOS technology. noise immunity This highly reliable process coupled with innovative Easy memory expansion with CE and OE options circuit design techniques, yields high-performance and low power consumption devices. CE power-down Fully static operation: no clock or refresh When CE is HIGH (deselected), the device assumes required a standby mode at which the power dissipation can be TTL compatible inputs and outputs reduced down with CMOS input levels. Single Power Supply Vdd = 1.65V to 2.2V (IS61WV51216EDALL) Easy memory expansion is provided by using Chip En- Vdd = 2.4V to 3.6V (IS61/64WV51216EDBLL) able and Output Enable inputs, CE and OE. The active Packages available: LOW Wr ite Enable (WE) controls both writing and read- ing of the memory. A data byte allows Upper Byte (UB) 48-ball miniBGA (6mm x 8mm) and Lower Byte (LB) access. 44-pin TSOP (Type II) Industr ial and Automotive Temperature Suppor t The device is packaged in the JEDEC standard 44-pin Lead-free available TSOP Type II and 48-pin Mini BGA (6mm x 8mm).
