FEATURES
128K x 16 HIGH-SPEED CMOS STATIC RAM WITH 3.3V SUPPLY
High-speed access time: 8, 10, 12, and 15 ns CMOS low power operation TTL and CMOS compatible interface levels Single 3.3V + 10%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 IS61LV12816 is a high-speed, 2,097,152-bit static
RAM organized as 131,072 words by 16 bits. It is fabricated using 1+51's high-performance CMOS technology. This highly r e l i a b l e 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 IS61LV12816 is packaged in the JEDEC standard 44-pin 400mil SOJ, 44-pin 400mil TSOP-2, and 48-pin 6*8mm TFBGA.

Note: 1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability.
