Note:  
1. XI is connected to XO of previous device.  
See Figure 4.  
Depth Expansion (Daisy The M67206H can be easily adapted for applications which require more than 16384  
words. Figure 4 demonstrates Depth Expansion using three M67206Hs. Any depth can  
be achieved by adding an additional M67206H.  
Chain) Mode  
The M67206H operates in the Depth Expansion configuration if the following conditions  
are met:  
1. The first device must be designated by connecting the First Load (FL) control  
input to ground.  
2. All other devices must have FL in the high state.  
3. The Expansion Out (XO) pin of each device must be connected to the Expansion In  
(XI) pin of the next device. See Figure 4  
4. External logic is needed to generate a composite Full Flag (FF) and Empty Flag  
(EF). This requires that all EF’s and all FFs be ORed (i.e. all must be set to generate the  
correct composite FF or EF). See Figure 4.  
5. The Retransmit (RT) function and Half-Full Flag (HF) are not available in the Depth  
Expansion Mode.  
Compound Expansion  
Module  
It is quite simple to apply the two expansion techniques described above together to cre-  
ate large FIFO arrays (see Figure 5).
