OPTIONAL CONFIGURATIONS
WIDTH EXPANSION CONFIGURATION
Word width may be increased simply by connecting together the control
signals of multiple devices. Status flags can be detected fromany one device.
The exceptions are the
EF
and
FF
functions in IDT Standard mode and the
IR
and
OR
functions in FWFT mode. Because of variations in skew between RCLK
and WCLK, it is possible for
EF
/
FF
deassertion and
IR
/
OR
assertion to vary
by one cycle between FIFOs. In IDT Standard mode, such problems can be
avoided by creating composite flags, that is, ANDing
EF
of every FIFO, and
separately ANDing
FF
of every FIFO. In FWFT mode, composite flags can
be created by ORing
OR
of every FIFO, and separately ORing
IR
of every
FIFO.
Figure 36 demonstrates a width expansion using two IDT72T3645/
72T3655/72T3665/72T3675/72T3685/72T3695/72T36105/72T36115/

be attained by adding additional IDT72T3645/72T3655/72T3665/72T3675/
72T3685/72T3695/72T36105/72T36115/72T36125 devices.
NOTES:
1. Use an AND gate in IDT Standard mode, an OR gate in FWFT mode.
2. Do not connect any output control signals directly together.
3. FIFO #1 and FIFO #2 must be the same depth, but may be different word widths.
