Customers are advised toobtain the latest version of this device specification before relying on any published information and before placing orders for products.FEATURES? High-speed access time:— 10, 12 ns CMOS low power operation Low stand-by power:—
Less than 5 mA (typ.) CMOS stand-by TTL compatible interface levels Single 3.3V power supply Fully static operation: no clock or refreshrequired Three state outputs Data control for upper and lower bytes Industrial temperature available256K x 16 HIGH SPEED ASYNCHRONOUSCMOS STATIC RAM WITH 3.3V SUPPLYDESCRIPTIONThe ISSI IS61LV25616AL is a high-speed, 4,194,304-bitstatic RAM organized as 262,144 words by 16 bits. It isfabricated using ISSI's high-performance CMOS technol-ogy. This highly reliable process coupled with innovativecircuit design techniques, yields high-performance and lowpower consumption devices.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 IS61LV25616AL is packaged in the JEDEC standard44-pin 400-mil SOJ, 44-pin TSOP Type II, 44-pin LQFP and48-pin Mini BGA (8mm x 10mm).FUNCTIONAL BLOCK DIAGRAMA0-A17CEOEWE256K x 16MEMORY ARRAYDECODERCOLUMN I/OCONTROLCIRCUITGNDVDDI/ODATACIRCUITI/O0-I/O7Lower ByteI/O8-I/O15Upper ByteUBLBFEBRUARY 2003
