Hi Sinan,
Well basically according to Freescale reps, they cannot comment until the merger is done. I've tried contacting them many times, but the answer is always the same-no overlapping product lines, etc, etc. I suppose we'll just have to wait and watch. Clearly Freescale's Kinetis and NXP's LPC series of MCUs are competitors. We have to see which line gets the axe.
I feel Kinetis is a little more user friendly than the LPC (But I confess that I haven't used LPC since 2012-they might have added some features). In all probability we might see LPC chips with Kinetis features and a new IDE along the lines of KDS for the same.
Or they might go the Volkswagen way with similar products but different brands under the same parent company.
