Descriptions

O

Capacitor 1- pad for internal DC/DC voltage converter

O

Capacitor 1+ pad for internal DC/DC voltage converter

O

Capacitor 2- pad for internal DC/DC voltage converter

O

Capacitor 2+ pad for internal DC/DC voltage converter

O

Capacitor 3+ pad for internal DC/DC voltage converter

O

DC/DC voltage converter output

I

Voltage adjustment pad. Applies voltage between V0 and VSS using a

resistive divider

This is the external input reference voltage (VREF) for the internal

I

voltage regulator. It is valid only when external VREF is used.

VEXT must be ≥ 2.4V and ≤ VDD2

When using internal VREF, this pad must be NC

Selects temperature coefficient of the reference voltage

I

TMPS = 0: -0.05% / °C

TMPS = 1: -0.2 % / °C

Select the internal voltage regulator or external voltage regulator,

I

VRS = 0: using the external VREF

VRS = 1: using the internal VREF
