62LV256

IS62LV256 32K x 8 LOW VOLTAGE STATIC RAM ISSI DESCRIPTION ® DECEMBER 2002 FEATURES Access time: 45, 70 ns Low active power: 70 mW Low standby power — 45 µW CMOS standby Fully static operation: no clock or refresh required TTL compatible inputs and outputs Single 3.3V power supply The ISSI IS62LV256 is a very high-speed, low power, 32,768-word by 8-bit static RAM. It is fabricated using ISSI's high-performance CMOS double-metal technology. When CE is HIGH (deselected), the device assumes a standby mode at which the power dissipation is reduced to 10 µW (typical) with CMOS input levels. Easy memory expansion is provided by using an active LOW Chip Enable (CE) input and an active LOW Output Enable (OE) input. The active LOW Write Enable (WE) controls both writing and reading of the memory. The IS62LV256 is pin compatible with other 32K x 8 SRAMs in 300-mil SOJ, 330-mil plastic SOP, and TSOP (Type I Normal and Reverse Bent) packages.
