IS61LV6416 64K x 16 HIGH-SPEED CMOS STATIC RAM WITH 3.3V SUPPLY FEATURES High-speed access time: 8, 10, 12, and 15 ns CMOS low power operation 250 mW (typical) operating 250 µW (typical) standby TTL compatible interface levels Single 3.3V power supply Fully static operation: no clock or refresh required Three state outputs Data control for upper and lower bytes Industrial temperature available DESCRIPTION The 1+51 IS61LV6416 is a high-speed, 1,048,576-bit static RAM organized as 65,536 words by 16 bits. It is fabricated using 1+51's high-performance CMOS technology. This highly reliable process coupled with innovative circuit design techniques, yields access times as fast as 8 ns with low power consumption. When CE is HIGH (deselected), the device assumes a standby mode at which the power dissipation can be reduced down with CMOS input levels. 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 IS61LV6416 is packaged in the JEDEC standard 44-pin 400mil SOJ, 44-pin 400mil TSOP-2, and 48-pin 6*8mm TFBGA.

All signals must be in valid states to initiate a Write, but any one can go inactive to terminate the Write. The Data Input Setup and Hold timing are referenced to the rising or falling edge of the signal that terminates the write. 6 Integrated Circuit Solution Inc.
