Preliminary
DESCRIPTION
The
ICSI
IC62LV1008L and IC62LV1008LL is a low voltage,
1,048,576 words by 8 bits, CMOS SRAM. It is fabricated using
ICSI
's low voltage, six transistor (6T), CMOS technology. The
device is targeted to satisfy the demands of the state-of-the-art
technologies such as cell phones and pagers.
When
CE1
is HIGH or CE2 is LOW (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 two Chip Enable
inputs,
CE1
and CE2. The active LOW Write Enable (
WE)
controls both writing and reading of the memory.
The IC62LV1008L and IC62LV1008LL are available in know
good die form and 48-pin 8*10mm TF-BGA.

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.
