Type: I: Input pin, O: Output pin, B: Bidirectional pin, P: Power supply pin, NC: No connection pin
Note: 1. NC pins must be left open. Do not connect any signal to these pins.
2. Pin names that start with Z are negative-logic signals.
3. V
SS0
is the logic system ground and V
SS1
is the SCSI interface ground.
4. Applications that use DRAM must insert resistors in the CAS and RAS lines, connect capacitors between these lines and ground, and take any
other measures necessary to prevent undershoot in the DRAM related circuits.
5. Since these circuits include buffers that sink 48 mA, adequate noise prevention measures must be applied.
