FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION
The ISSI IS62C5128BL and IS65C5128BL are high-speed,
4,194,304-bit static RAMs organized as 524,288 words by
8 bits. They are fabricated using ISSI's high-performance
CMOS technology.This highly reliable process coupled with
innovative circuit design techniques, yields access times as
fast as 45ns with low power consumption.
When CE is HIGH (deselected), 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, 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 IS62C5128BL and IS65C5128BL are packaged in the
JEDEC standard 32-pin sTSOP-I, 32-pin SOP and 32-pin
TSOP-II packages
