DEPTH EXPANSION CONFIGURATION — DAISY CHAIN TECHNIQUE
(WITH PROGRAMMABLE FLAGS)
These devices can easily be adapted to applications requiring more than
256/512/1,024/2,048/4,096 words of buffering. Figure 30 shows Depth
Expansion using three IDT72V205/72V215/72V225/72V235/72V245s.
Maximumdepthislimitedonlybysignalloading.
Followthesesteps:
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 30.
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 30.
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.
8. In Daisy Chain mode, the flag outputs are single register-buffered and
thepartialflagsareinasynchronoustimingmode.
