DEPTH EXPANSION — IDT72801/72811/72821/72831/72841/72851
can be adapted to applications that require greater than 256/512/1,024/
2,048/4,096/8,192 words. The existence of double enable pins on the read
and write ports allow depth expansion. The Write Enable 2/Load (WENA2,
WENB2) pins are used as a second write enables in a depth expansion
configuration, 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 controlled by expansion logic to direct the flow
of data. A typical application would have the expansion logic alternate data
accessfromonedevicetothenextinasequentialmanner. TheseFIFOsoperate
intheDepthExpansionconfigurationwhenthefollowingconditionsaremet:
1. WENA2/LDA and WENB2/LDB pins are held HIGH during Reset so
that these pins operate as second Write Enables.
2. External logic is used to control the flow of data.
Please see the Application Note" DEPTH EXPANSION OF IDT'S SYN-
CHRONOUS FIFOs USING THE RING COUNTER APPROACH" for details
of this configuration.
NOTES:
1
. Industrial temperature range product for 15ns and 25ns speed grade are available as a standard device.
2. Green parts are available. For specific speeds and packages contact your sales office.
