DESCRIPTIONThe ISSI IS61LV12816L is a high-speed, 2,097,152-bitstatic RAM organized as 131,072 words by 16 bits. It isfabricated using ISSI's high-performance CMOStechnology. This highly reliable process coupled withinnovative circuit design techniques, yields access timesas fast as 8 ns with low power consumption.When CE is HIGH (deselected), the device assumes astandby mode at which the power dissipation can bereduced down with CMOS input levels.Easy memory expansion is provided by using Chip Enableand Output Enable inputs, CE and OE. The active LOWWrite Enable (WE) controls both writing and reading of thememory. A data byte allows Upper Byte (UB) and LowerByte (LB) access.The IS61LV12816L is packaged in the JEDEC standard44-pin TSOP (Type II), 44-pin LQFP, and 48-pin mini BGA(6mm x 8mm).FUNCTIONAL BLOCK DIAGRAMA0-A16DECODER128Kx16MEMORY ARRAYVDDGNDI/O0-I/O7Lower ByteI/O8-I/O15Upper ByteI/ODATACIRCUITCOLUMN I/OCEOEWEUBLBCONTROLCIRCUITCopyright © 2005 Integrated Silicon Solution, Inc.
