Name
Description
1
VBAT
Depending on the VBAT/Reset Signals Operation mode (Section
)this can be
used as Voltage supply for the DUT. Due to this connection, no external power
supply is needed for the DUTs. This pin must be connected if there is no other
power supply (e.g., battery).
2
XTAL
Calibration
Pulse
This pin can be used as a reference pulse during the automatic crystal
calibration. More details are given in Section
. The crystal trim pulse can
also be supplied in the UART RX device pin. This is the recommended scenario.
However, there may be hardware limitations where the UART RX pin cannot be
used. In such cases, the particular PLT header pin should be used.
6
GND
Ground pin. This pin must be connected.
7
DUT TX
This is connected to the device UART TX pin. This pin must be connected.
8
VPP
Not used for DA1470x
9
DUT RX
This is connected to the device UART RX pin. This pin can also provide the
crystal calibration reference pulse for the automatic crystal (XTAL) trim
procedure, as described in Section
This pin must be connected.
10
RST
The reset signal must be connected mostly if battery powered devices are used.
A power cycle of VBAT will produce a Power on Reset (POR) in which case the
RST-wire is not needed. However, using the RST signal is faster, whereas VBAT
POR needs time to discharge.

CPLD switches S1, S2, S3 and S4 are controlled by the software via the Golden Unit.
