32K x 8 LOW VOLTAGE STATIC RAM
• Access time: 45, 70 ns
• Low active power: 70 mW
• Low standby power
— 45 µW CMOS standby
• Fully static operation: no clock or refresh
• 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.
