IS62LV256
ISSI®
32K x 8 LOW VOLTAGE STATIC RAM
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
DESCRIPTION
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.

Notes:
1. Stress greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation of the
device at these or any other conditions above those indicated in the operational sections
of this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect reliability.
