ORDERING INFORMATION
access from one device to the next in a sequential manner.
The IDT72421/7221/72211/72221/72231/72241 operates in
the Depth Expansion configuration when the following condi-
tions are met:
1. The WEN2/
LD
pin is held HIGH during Reset so that this pin
operates a second Write Enable.
2. External logic is used to control the flow of data.
Please see the Applicatioin Note" DEPTH EXPANSION OF
IDT'S SYNCHRONOUS FIFOs USING THE RING COUNTER
APPROACH" for details of this configuration.
DEPTH EXPANSION -
The IDT72421/7221/72211/72221/
72231/72241 can be adapted to applications when the re-
quirements are for greater than 64/256/512/1024/2048/4096
words. The existence of two enable pins on the read and write
port allow depth expansion. The Write Enable 2/Load pin is
used as a second write enable in a depth expansion configu-
ration thus the Programmable flags are set to the default
values. Depth expansion is possible by using one enable
input for system control while the other enable input is con-
trolled by expansion logic to direct the flow of data. A typical
application would have the expansion logic alternate data
