Interface Pin Name Type Description
IOVDD Supply Analog (Driver) side Voltage
Rail Input for IO ring (1.8V to
3.3V Nominal +/- 10%). All
digital IO pads use IOVDD only.
IOVDD can be an AC isolated
version of PVDD but is not
required.
VSENSE Analog input Voltage Regulator Voltage
Sense Input - Feedback of Load
side of inductor.
GSENSE
Analog input
core power ground sense
LX
Supply
Core voltage regulator output
VREN Analog input Internal Voltage regulator
enable:
PVDD = enable
VSS/GND = disable
VREN cannot be dynamically
changed. VREN has to be
stable/static when PVDD
becomes stable.
DVDD Supply 1.8 V (nominal) +/- 10%
regulated core power supply. In
Deep Sleep state, it can be
configured to go to 1.35V
(nominal) +/- 10% to reduce
sleep/leakage power.
DVDD_2 Supply 1.8 V (nominal) +/- 10%
regulated core power supply.
Connected to same source as
DVDD pin. In Deep Sleep state,
it can be configured to go to
1.35V (nominal) +/- 10% to
reduce sleep/leakage power.
Clocking HYB_XTALI Logic input Crystal/oscillator input for
System Clock. If no external
XTAL is connected, keep these
pins as no-connect.
HYB_XTALO Logic output Crystal output for System clock.
If no external XTAL is
connected, keep these pins as
no-connect.
RTC_XTALI Logic input 32.768 kHz Crystal/oscillator
input for RTC clock. If RTC
XTAL is not connected, this pin
has to be grounded (to 0).
