Application Information

As mentioned in chapter 2, the DA14AVDDECT functionality is defined in software and the software

specifics are detailed in separate documents. The DA14AVDDECT can be operated stand-alone or

controlled from a host application through the API interface. The on-board FLASH memory can be

used to store the custom code.

The following points highlight some hardware-specific aspects of application implementation:

diversity

is, the internal antenna combined with an external antenna

from the internal printed antenna and allows two external antennas to be used

information please refer to [4]), the supply circuit should be copied from the reference

application used for certification. If it is desired to deviate from the reference application,

please note the following, and it may not be possible to leverage the Limited Modular

Approval any more:

external DCDC boost converter will be required if two AA applications are targeted

current draw depending on the RF TX output power levels). An optimal battery efficiency is

obtained if +VRF_PA_2 is sourced from a DCDC power supply adjusted within 0.5 V to 3.5

V based on the target output power levels

dissipation increases the module's temperature. Please make sure that the chip temperature

does not exceed its operational temperature range, especially when other functions are also

enabled. Since the module includes an on-board temperature sensor to facilitate chip

temperature detection, how to protect the chip from overheating needs to be implemented in

software and is not described in further detail in this document

CODEC, please map the GPIOs accordingly. It is implemented in software and is not described

in further detail in this document
