DESCRIPTION
The
ISSI
IS62C256 is a low power, 32,768 word by 8-bit
CMOS static RAM. It is fabricated using
ISSI
's high-
performance, low power CMOS technology.
When
CS
is HIGH (deselected), the device assumes a standby
mode at which the power dissipation can be reduced down to
250
μ
W (typical) at CMOS input levels.
Easy memory expansion is provided by using an active LOW
Chip Select (
CS
) input and an active LOW Output Enable (
OE
)
input. The active LOW Write Enable (
WE
) controls both writing
and reading of the memory.
The IS62C256 is pin compatible with other 32K x 8 SRAMs in
plastic SOP or TSOP (Type I) package.
