DESCRIPTION
廬
JANUARY 2000
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 碌W (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 plastic DIP and SOJ, 330-mil plastic SOP, and
TSOP (Type I) packages.
