4-1. S2- Harvesting mode selection
Setting Label Function Dip Switch Setting
MODE0 Selects RF or PV harvesting:
The PV harvesting range supported in the pre-loaded application is 1.7V -
2V,
High = RF
Low = PV
MODE1 Selects Harvesting to load:
Disabled = harvesting power is only used to charge the storage element.
VBAT is used to provide power to the load.
This mode supports characterization of the harvesting performance.
Enabled = harvesting power is used to power the load first, and the remaining
power is used to charge the storage element.
VBAT is used to provide power to the load when the harvesting and stored
power are not enough.
This is the normal operation mode of the SoC
Note: This setting is only supported when MODE2 is set to low (non-rechargeable
battery)
High = Disabled
Low = Enabled
MODE2 Select battery type:
High = connect a high-voltage battery or storage device at VBALI to start
operation.
RF-only or PV-
only harvesting settings are enabled based on MODE0 setting.
MODE1 setting is ignored.
Low = connect a non-rechargeable battery at VBAT to start operation.
RF-only or PV-only harvesting settings are enabled based on the MODE0
setting. Harvesting to load is enabled or disabled based on the MODE1
setting.
High = Battery/ storage
device on VBATLI pin
Low = non-rechargeable
battery on VBAT pin

7-2. Harvesting mode setting
See Section 4-1 for a detailed description of the harvesting mode switch setting
1. Mode0 = Low
select PV harvesting, connect PV cell to J4
2. Mode1 = High (disabled)
The harvesting power is only used to charge the storage element. VBAT (USB power) is used to provide power to
the load.
3. Mode3 = High
Connect the 4.2V Li-Ion battery to J6
7-3. Power on
1. Connect the USB power cable to USB1
2. Push S1 to power on and reset the DVB
7-4. RF harvesting
1. If RF harvesting shall be used, set Mode0 switch to high
2. Connect 900 MHz antenna to ANT3
3. Make sure there is a continuous and stable 900 MHz radio transmission source nearby

VBATT
Battery input from 1.1V to 3.3V. Must connect to a
10uF capacitor if VBATTLI is used
Note: see section 11 PMU configurations
VBATTLI
2.7 V to 4.2 V lithium ion battery supply in place of VBAT. If
lithium ion battery is not used, this pin must be connected to
ground
VDDPA PA power supply
VSTORE
Connection to a large storage capacitor (typical value 220uF)
Must be grounded when the harvester is not used.
VHARV
Connection to a storage capacitor of typical value 10uF.
Must be grounded when the harvester is not used.
DVDD1P, AVDD1P PMU generated digital and analog core supply outputs
DVDD1, AVDD1

Note: DVDD1 is connected to DVDD1P via R2 0-ohm resistor
AVDD1 is connected to AVDD1P via R3 0-
ohm resistor in this
module
VDDIOP
PMU generated 1.8V IO supply output
Note: see section 8-1 PMU configurations
VAUX
Auxiliary supply output of typical value oof 3.2V, used
internally by the PMU
VDDIO
Power supply input for the digital and analog IO circuits
Note: see section 8-1 PMU configurations

19 / 24
8-1. PMU configuration
The PMU must be configured correctly to ensure correct operation. The following modes of operation
are supported by the PMU:
(a) One external power supply or battery with an external IO supply:
For applications that cannot support fixed 1.8 V IO supply
 Connect VBAT to VDDIO
 Connect VAUX to VDDIOP
 Disable IO supply generation
(b) One external power supply or battery with an internally generated IO supply:
For applications that can use a fixed 1.8 V IO supply for better power consumption or VBAT <= 1.8
V
 Connect VDDIOP to VDDIO
(c) Energy harvesting with no battery and internally generated IO supply:
 Connect VBAT to ground
 Connect VDDIOP to VDDIO
