The Cypress' charge controller based on CY8CLED04D01 has an in-built MPPT algorithmn. Is it possible to port that algorithm to a PSoC 1 device? Is there any advantage of using this device?

Sorry for posting the question again, I think I posted initially in the wrong location.

No, you are right here, I answered one of your other threads here:

This ap note is accompanied by a project file set, written in C.

You could possibly port it to your own HW design.

PowerPSoC has additional power peripherals like hysteretic controllers, CSA etc in addition to the core (which is same as the PSoC 1 core - M8C). Indeally, it should be possible to port the code to a PSoC 1 device but you will have to use external components. 

The key advantage of Cypress' solution is that it is is a single chip solution for battery charging and driving LEDs. PowerPSoC has 4 channels of the power peripherals, these can be used for LED driving as well. So, with one PowerPSoC device you can implement a single chip solution for charging the battery and driving LEDs.

You can find all the details about the Cypress's MPPT solution at the link -

The Application Note that Dana mentioned has all the details about this solution along with the firmware. The AN link is
