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
required even if the ball 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 balls must be connected; each VCC ball
requires a 10 nF and a 0.1 µF capacitor.
Ground. All VSS balls must be connected.
