DESCRIPTION
The
ISSI
IS62VV51216LL is a high-speed, 8M bit static
RAMs organized as 512K words by 16 bits. It is fabricated
using
ISSI
's high-performance CMOS technology. This
highly reliable process coupled with innovative circuit
design techniques, yields high-performance and low power
consumption devices.
For the IS62VV51216LL, when CS1 is HIGH (deselected)
or when CS2 is LOW (deselected) or when CS1 is LOW,
CS2 is HIGH and both LB and UB are HIGH, the device
assumes a standby mode at which the power dissipation
can be reduced down with CMOS input levels.
Easy memory expansion is provided by using Chip Enable
and Output Enable inputs. 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 IS62VV51216LL is packaged in the JEDEC standard
48-pin mini BGA (7.2mm x 8.7mm).
