VBAT On with Reset
Figure 22: VBAT On with Reset
In this mode the reset of the DUTs will be performed by the PLT Reset line as shown in
During this mode, the PLT VBAT line continuously provides power to the DUTs and the DUTs are
reset using the PLT Reset line.
Power supply can be provided to the DUTs if the PLT VBAT line is connected to the DUTs. However,
for battery powered DUTs or for DUTs with an external power supply VBAT should not be connected.
For such devices, only the connection to the PLT Reset line is mandatory.
6.9.2.1
Firmware Download
When the firmware download procedure begins, PLT will reset the DUTs using the PLT Reset line.
The VBAT line is already active and remains active for the entire PLT test and memory programming
procedure. If there are devices that failed to download firmware, the PLT will reset all the DUTs again
and retry to download firmware to all of them even if these have succeeded. This is different
approach from the VBAT Only procedure (Section
), since the Reset line is a single hardware
line that cannot be differently controlled for each DUT, as opposed to the VBAT lines. The retry
operation and the amount of retries can be configured by the user. Check
When the production testing has finished, the above procedure will be repeated for the memory
programming, as a different firmware needs to be downloaded to the DUTs.
6.9.2.2
Current Measurement
If the DUTs are powered through the PLT HW using the VBAT line, or if they are powered using a
single common line from an external power supply, the Current Measurement Test (
) for the
DA1470x are supported as described in the Section
. If the DUTs are powered independently or
have their own power supply (e.g., have a battery) then the current measurement tests are not
supported.
6.10 Custom Memory Data
The following section
describes the PLT ‘
Custom Memory Data
’ configuration and programming
procedure.
The PLT supports programming custom user data of any size up to 256 bytes, to any memory and
from any start address. Custom data can be entered to the PLT by the three input methods described
in

Description
CSV file
Users can provide a path to a CSV file that will contain the custom memory data for
each DUT. The format of the CSV file is specific and is provided in Section
