2 Using the DiskOnChip 9x12 BGA-to-32-Pin DIP Adapter
2.1 Jumper
Settings
The adapter contains the following four jumpers:
•
J1
: Not used, and should be left open.
•
J2
: Used for the device LOCK# pin. The default setting is open and leaves the LOCK# pin
negated.
•
JP1
and
JP2
: Used for matching the host voltage supplied by the EVB or the GANG
Programmer, either 3.3V or 5V. Also used for setting the VCCQ for DiskOnChip. See Table 1
for the correct settings.
Table 1: Jumper Settings for Voltage Configuration
Host Voltage
Required VCCQ Voltage
JP1
JP2
5V 3.3V 1-2
2-3
5V 1.8V 2-3
2-3
3.3V 3.3V
1-2 1-2
3.3V 1.8V
2-3 1-2
Note: For devices where VCCQ=VCC, a VCCQ voltage setting of 1.8V will not work.
2.2 Inserting the Adapter into a DIP Socket
To insert the adapter into a DiskOnChip EVB or GANG Programmer equipped with a DIP
socket:
1. Identify pin #1 of the DIP adapter by locating the white triangle on the PCB. Pin #1 is located on
the left side of the triangle. Figure 1 illustrates the location of the white triangle.
2. Insert the adapter by aligning pin #1 of the adapter with pin #1 of the DIP socket on the EVB or
GANG Programmer.
