DESCRIPTION
The
organized as 32,768 words by 16 bits. It is fabricated using
ICSI
able process coupled with innovative circuit design techniques,
yields fast access times 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 IS61C3216 is packaged in the JEDEC standard 44-pin
400mil SOJ and 44-pin 400mil TSOP-2.
