Depth Expansion Configuration
(with Programmable Flags)
The CY7C42X5 can easily be adapted to applications requir-
ing more than 64/256/512/1024/2048/4096 words of buffering.
Figure 2 shows Depth Expansion using three CY7C42X5s. Maxi-
mum 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.
4. The Read Expansion Out (RXO) pin of each device must be
tied to the Read Expansion In (RXI) pin of the next device.
5. All Load (LD) pins are tied together.
6. The Half-Full Flag (HF) is not available in the Depth Expansion
Configuration.
7. EF, FF, PAE, and PAF are created with composite flags by
ORing together these respective flags for monitoring. The
composite PAE and PAF flags are not precise.
