TERMINAL FUNCTIONS (continued)
TERMINAL
I/O
DESCRIPTION
NAME
NO.
Input signal indicating default VDCDC1 voltage, 0 = 1.2 V, 1 = 1.6 V DEFDCDC1 can also be
DEFDCDC1
10
I
connected to a resistor divider between VDCDC1 and GND, if the output voltage of the DCDC1
converter is set in a range from 0.6 V to VINDCDC1 V.
Input signal indicating default VDCDC2 voltage, 0 = 1.8 V, 1 = 3.3 V DEFDCDC2 can also be
DEFDCDC2
32
I
connected to a resistor divider between VDCDC2 and GND, if the output voltage of the DCDC2
converter is set in a range from 0.6 V to VINDCDC2 V.
Input signal indicating default VDCDC3 voltage, 0 = 1.8 V, 1 = 3.3 V DEFDCDC3 can also be
DEFDCDC3
1
I
connected to a resistor divider between VDCDC3 and GND, if the output voltage of the DCDC3
converter is set in a range from 0.6 V to VINDCDC3 V.
DCDC1_EN
25
I
VDCDC1 enable pin. A logic high enables the regulator, a logic low disables the regulator.
DCDC2_EN
24
I
VDCDC2 enable pin. A logic high enables the regulator, a logic low disables the regulator.
