Identification.
For Mobile DiskOnChip 16MB, up to four chips can be cascaded
in the same memory window, according to the following
assignment:
Chip 1 = ID1, ID0 = VSS, VSS (0,0); required for single chip
Chip 2 = ID1, ID0 = VSS, VCC (0,1)
Chip 3 = ID1, ID0 = VCC, VSS (1,0)
Chip 4 = ID1, ID0 = VCC, VCC (1,1)
For Mobile DiskOnChip 32MB, up to two chips can be cascaded in
the same memory window, according to the following assignment:
Chip 1 : ID1=VSS, ID0 = VSS ;required for single chip
Chip 2 : ID1=VSS, ID0 = VCC
Interface Configuration, 1 for 16-bit interface mode, 0 for 8-bit
interface mode.
Lock, active low. When active, provides full hardware data
protection of selected partitions.
Busy, active low, open drain. Indicates that DiskOnChip is
initializing and should not be accessed. A 10 K
required even if the ball is not used.
Interrupt Request. Requires a 10 K
Reset, active low.
I/O power supply. Sets the logic ‘1’ voltage level range of I/O
balls/pins. VCCQ may be either 2.5V to 3.6V or 1.65V to 2.0V.
Requires a 10 nF and 0.1 µF capacitor.
