IS61C6416AL IS64C6416AL IS62C6416AL IS65C6416AL ISSI 64K x 16 HIGH-SPEED CMOS STATIC RAM JUNE 2005 FEATURES DESCRIPTION The ISSI IS61C6416AL, IS62C6416AL, IS64C6416AL and IS61C6416AL and IS64C6416AL IS65C6416AL are high-speed, 1,048,576-bit static RAMs High-speed access time: 12 ns, 15ns organized as 65,536 words by 16 bits. They are fabricated Low Active Power: 175 mW (typical) using ISSI s high-performance CMOS technology. This highly reliable process coupled with innovative circuit design tech- Low Standby Power: 1 mW (typical) niques, yields access times as fast as 12 ns with low power CMOS standby consumption. IS62C6416AL and IS65C6416AL High-speed access time: 35 ns, 45ns When CE is HIGH (deselected), the device assumes a standby mode at which the power dissipation can be reduced Low Active Power: 50 mW (typical) down with CMOS input levels. Low Standby Power: 100 W (typical) CMOS standby Easy memory expansion is provided by using Chip Enable and Output Enable inputs, CE and OE. The active LOW Write TTL compatible interface levels Enable (WE) controls both writing and reading of the memory. Single 5V 10% power supply A data byte allows Upper Byte (UB) and Lower Byte (LB) Fully static operation: no clock or refresh access. required The IS61C6416AL, IS62C6416AL, IS64C6416AL and Available in 44-pin SOJ package and IS65C6416AL are packaged in the JEDEC standard 44-pin 44-pin TSOP (Type II) 400-mil SOJ and 44-pin TSOP (Type II).
