256K x 16 LOW VOLTAGE, LOW POWER
CMOS STATIC RAM
DESCRIPTION
The
ISSI IS62Ux25616 series is a low voltage, 262,144
words by 16 bits, CMOS SRAM. It is fabricated using
ISSI's low voltage, six transistor (6T), CMOS technology.
The series is targeted to satisfy the demands of the state-
of-the-art technologies such as cell phones and pagers.
When
CE is HIGH (deselected), the device assumes a
standby mode at which the power dissipation can be
reduced down with CMOS input levels. Additionally, easy
memory expansion is provided by using Chip Enable and
Output Enable inputs,
CE and OE. The active LOW Write
Enable (
WE) controls both writing and reading of the
memory. A data byte allows Upper Byte (
UB) and Lower
Byte (
LB) access.
The IS62Ux25616 series is packaged in the 48-ball mini
BGA and the 44-pin sTSOP (Type II).
