Commercial And Industrial Temperature Ranges
DEPTH EXPANSION CONFIGURATION
(WITH PROGRAMMABLE FLAGS)
These devices can easily be adapted to applications requir-
ing more than 256/512/1,024/2,048/4,096 words of buffering.
Figure 21 shows Depth Expansion using three IDT72205LB/
72215LB/72225LB/72235LB/72245LBs. Maximum depth is
limited only by signal loading. Follow these steps:
1. The first device must be designated by grounding the
First Load (
FL) control input.
2. All other devices must have
FL in the HIGH state.
3. The Write Expansion Out (
WXO) pin of each device
must be tied to the Write Expansion In (
WXI) pin of
the next device. See Figure 21.
4. The Read Expansion Out (
RXO) pin of each device
must be tied to the Read Expansion In (
RXI) pin of
the next device. See Figure 21.
5. All Load (
LD) pins are tied together.
6. The Half-Full Flag (
HF) is not available in this Depth
Expansion Configuration.
7.
EF, FF, PAE, and PAF are created with composite
flags by ORing together every respective flags for
monitoring. The composite
PAE and PAF flags are not
precise.
