3.1 Signal Descriptions
The SYM53C180 is packaged in a 192-pin Ball Grid Array (BGA) shown
in Figure 3.1 and Figure 3.2. The SYM53C180 signal grouping is shown
in Figure 3.3. Tables 3.1 through 3.4 list the signal descriptions grouped
by function:
SCSI A Side Interface Pins (Table 3.1)
SCSI B Side Interface Pins (Table 3.2)
Chip Interface Control Pins (Table 3.3)
Power and Ground Pins (Table 3.4)
Figure 3.1 and Figure 3.2 display the left and right halves of the
SYM53C180 192-pin BGA top view.
