@prabhakar_deosthali- I'm sorry to say I don't know about the process geometry they plan to use. I'm not sure they've even made those decisions, though I did get the sense that this project was pretty far along. I asked if products would be available within two years, and I got the sense from the answer that it could be much sooner than that. If you look at Renesas' MCU roadmap, they are planning some pretty aggressive shrinks over the next couple of years, including skipping two nodes in some cases to move to 40-nm. But my understanding is that, as you say, analog blocks put significant constraints on the geometry that can be employed.
"Better late than never" is what I'd like to comment on this. Renesas, though a market leader ( in terms of share ) in the microcontroller market, has made a late entry into the mixed-signal segment of this business.
Adding to this fact is the latency of another 2 years ( well, almost ) before the part can be used by the user.
If you look at Silabs or Microchip, I find them more aggressive in this market. Further, if you also look at their capability in delivering discreet analog components, then they are way ahead than most of their peers.
I like the strategy adopted by Microchip in this market - supply the part(s), augment the same with useful software, hardware & other utilities. Something that others should learn...
Mixed signal SOCs have been around for quite some time now. It is a good move by Renesas to offer mixed signal micro-controllers. I beileve Analog blocks put some constraint on the geometry . IN what geometry Renesas plans to offer these micro-controllers?
This is interesting when compared to the recent Velocity Lab announcement. http://www.eetimes.com/electronics-products/embedded-tools/4209557/-Renesas--Velocity-Lab-aims-to-speed-embedded-systems-development
It seems to me that Renesas realizes the eco-system for these types of solutions will be critical and is already showing they are serious about giving customers a real solution- not just slapping some analog onto an existing MCU.
