| IS61LV12824 128K x 24 HIGH-SPEED CMOS STATIC RAM WITH 3.3V SUPPLY FEATURES * High-speed access time: 8, 9, 10, 12 ns * CMOS low power operation -- 756 mW (max.) operating @ 8 ns -- 36 mW (max.) standby @ 8 ns * TTL compatible interface levels * Single 3.3V power supply * Fully static operation: no clock or refresh required * Three state outputs * Available in 119-pin Plastic Ball Grid Array (PBGA) and 100-pin TQFP packages. * Industrial temperature available ISSI (R) DECEMBER 1999 DESCRIPTION The ISSI IS61LV12824 is a high-speed, static RAM organized as 131,072 words by 24 bits. It is fabricated using ISSI's highperformance 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 CE1, CE2 are HIGH and CE2 is LOW (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, CE1, CE2, CE2 and OE. The active LOW Write Enable (WE) controls both writing and reading of the memory. The IS61LV12824 is packaged in the JEDEC standard 119-pin PBGA and 100-pin TQFP.

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. 8 Integrated Silicon Solution, Inc. -- 1-800-379-4774 Rev.
