IS61WV25616ALL/ALS IS61WV25616BLL/BLS IS64WV25616BLL/BLS 256K x 16 HIGH SPEED ASYNCHRONOUS CMOS STATIC RAM JULY 2010 DESCRIPTION The ISSI IS61WV25616Axx/Bxx and IS64WV25616Bxx FEATURES HIGH SPEED: (IS61/64WV25616ALL/BLL) • High-speed access time: 8, 10, 20 ns • Low Active Power: 85 mW (typical) • Low Standby Power: 7 mW (typical) CMOS standby are high-speed, 4,194,304-bit static RAMs organized as 262,144 words by 16 bits. It is fabricated using ISSI's highperformance CMOS technology. This highly reliable process coupled with innovative circuit design techniques, yields high-performance and low power consumption devices. LOW POWER: (IS61/64WV25616ALS/BLS) • High-speed access time: 25, 35, 45 ns • Low Active Power: 35 mW (typical) • Low Standby Power: 0.6 mW (typical) CMOS standby • Single power supply — VDD 1.65V to 2.2V (IS61WV25616Axx) • • • • • When CE is HIGH (deselected), the device assumes a standby mode at which the power dissipation can be reduced down with CMOS input levels. — VDD 2.4V to 3.6V (IS61/64WV25616Bxx) Fully static operation: no clock or refresh required Three state outputs Data control for upper and lower bytes Industrial and Automotive temperature support Lead-free available Easy memory expansion is provided by using Chip Enable and Output Enable inputs, CE and OE. The active LOW Write Enable (WE) controls both writing and reading of the memory. A data byte allows Upper Byte (UB) and Lower Byte (LB) access. The IS61WV25616Axx/Bxx and IS64WV25616Bxx are packaged in the JEDEC standard 44-pin TSOP Type II and 48-pin Mini BGA (6mm x 8mm).
