    Programmable Voltage Reference




      I am using a PSoC 4 Module (CYBLE-214009-00) and I can't find the Programmable voltage reference  component (PVref) on the PSoC creator.  ( www.cypress.com/file/274656/download )


      I would like to use it in order to measure the VCC (Battery voltage in my case) without an external voltage divider.


      I plan to use and ADC with VCC as a reference and to sample the PVref, than back calculating VCC.


      why this component is missing ?




      * Or If you can recommend on any other known practice to measure VCC without an external voltage divider.
