When connecting DiskOnChip G4 128MB (1Gb) using a standard interface, up to four devices can
be cascaded with no external decoding circuitry. Figure 15 illustrates the configuration required to
cascade four devices on the host bus (only the relevant cascading signals are included in this figure,
although all other signals must also be connected). All pins/balls of the cascaded devices must be
wired in common, except for ID0 and ID1. The ID input pins/balls are strapped to VCC or VSS,
according to the location of each DiskOnChip. The ID pin/ball values determine the identity of each
device. For example, the first device is identified by connecting the ID pins/balls as 00, and the last
device by connecting the ID pins/balls as 11. Systems that use only one DiskOnChip G4 128MB
(1Gb) must connect the ID pins/balls as 00. Additional devices must be configured consecutively as
01, 10 and 11.
When DiskOnChip G4 128MB (1Gb) uses a multiplexed interface, the value of ID[1] is set to logic
0. Therefore, only two devices can be cascaded using ID[0].
DiskOnChip G4 256MB (2Gb) devices cannot be cascaded when using a multiplexed interface.
