VDD

PWR

Power supply, nominally 3.3V.

2

GND

GND

Ground pin.

3

rcomp_NC

-

The DB2000Q specification calls this pin RCOMP. This pin is a true No Connect on

the 9QXL2000 device, since it is not needed. Any existing connections on the board

may remain to support non-DB2000Q devices.

4

vdd_NC

-

The DB2000Q specification calls this pin VDD. This pin is a true No Connect on the

9QXL2000 device, since it is not needed. Any existing connections on the board may

remain to support non-DB2000Q devices.

5

NC

-

No connection.
