Hardware Platform Configuration
Options
MCU Clock
Frequency
- Provides option to choose either
8MHz or 16MHz clock frequency selection for the
MCU
- Depending on the clock frequency
selection the power consumption of device is included accordingly during battery
life
calculation
Serial/OTA Bootloader
- Depending on availability of
bootloader in the application, corresponding option is
chosen
- Presence of bootloader will
consume more power due to bootloader
initialization
Full
Battery
Capacity
- Depending on end product’s
battery specification user have to input corresponding
value
- Field
accepts
unit of battery capacity as
mAh.
If
the battery capacity is not specified in mAh,
appropriate
conversion
is
required.
Self-discharge of the
Battery
- A battery performs well when
new.
But
the capacity begins to
reduce
with use and time.
- Depending on the battery type and characteristics,
the
user
must
specify the
amount
of charge leaked due to self-discharge in percentage
format
Usable
Capacity
of the
Battery
- To
ensure
reliable operation over many years, the design engineers shall include a reserve
and below which battery is
marked
as
dead
- In general 15-20% of battery
capacity would be considered as
unusable
- Depending on the battery type and characteristics,
the
user
may
have to specify
the
unusable capacity of the battery in percentage
format

Capacity
External
32kHz
Crystal
- Based on
the
product hardware specification,
the
design may or may not have an external
32kHz
crystal for periodic
wake-up
during sleep
state
- Option are
selected
depending on the availability of external
32kHz
crystal
