FUNCTIONAL BLOCK DIAGRAM
DESCRIPTION
The ICSI IC61LV6416 is a high-speed, 1,048,576-bit static
RAM organized as 65,536 words by 16 bits. It is fabricated
using ICSI's high-performance CMOS technology. This highly
reliable process coupled with innovative circuit design
techniques, yields access times as fast as 8 ns 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 IC61LV6416 is packaged in the JEDEC standard 44-pin
400mil SOJ, 44-pin 400mil TSOP-2, and 48-pin 6*8mm TFBGA.
