IS64WV6416BLL Long-term Support World Class Quality IS61WV6416BLL 64K x 16 HIGH-SPEED CMOS STATIC RAM APRIL 2019 FEATURES DESCRIPTION The ISSI IS61/64WV6416BLL is a high-speed, 1,048,576- High-speed access time: bit static RAM organized as 65,536 words by 16 bits. 12 ns: 3.3V + 10% It is fabricated using ISSI s high-perfor mance CMOS 15 ns: 2.5V-3.6V technology. This highly reliable process coupled with in- novative circuit design techniques, yields access times as CMOS low power operation: fast as 12ns (3.3V + 10%) and 15ns (2.5V-3.6V) with low 50 mW (typical) operating power consumption. 25 W (typical) standby When CE is HIGH (deselected), the device assumes TTL compatible interface levels a standby mode at which the power dissipation can be Fully static operation: no clock or refresh reduced down with CMOS input levels. required Three state outputs Easy memory expansion is provided by using Chip Enable and Output Enable inputs, CE and OE. The active LOW Data control for upper and lower bytes Write Enable (WE) controls both writing and reading of the Automotive Temperature Available memor y. A data byte allows Upper Byte (UB) and Lower Lead-free available Byte (LB) access. The IS61/64WV6416BLL is packaged in the JEDEC stan- dard 44-pin TSOP-II, 44-pin 400-mil SOJ, and 48-pin mini BGA (6mm x 8mm).
