Multiplexed bus. Address and data signals.
Output Enable, active low.
Write Enable, active low.
Sets multiplexed interface. Multiplexed mode is entered when a
rising edge is detected on this pin/ball.
Identification. For DiskOnChip Millennium Plus 16MB, up to two
chips can be cascaded in the same memory window, according to
the following assignment:
Chip 1 = ID0 = VSS; must be used for single chip configuration
Chip 2 = ID0 = VCC
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
even if the pin is not used.
Interrupt Request. Requires a 10 KΩ pull-up resistor.
Reset, active low.
I/O power supply. Requires a 10 nF and a 0.1 µF capacitor.
For 16MB devices, VCCQ may be either 2.7V to 3.6V or 1.65V to
1.95V.
For 32/64MB devices, VCCQ is 2.7V to 3.6V
Device supply. All VCC pins must be connected; each VCC pin
requires a 10 nF and 0.1 µF capacitor.
Ground. All VSS pins must be connected.
Reserved signal that is not connected internally and must be left
floating to guarantee forward compatibility with future products. It
should not be connected to arbitrary signals.
