This is the first time I've ever heard about communication chips form Renesas. Are these components came to them through any acquisition?

The acquisition of the Modem Design Team (~1000 people) of Nokia by Renesas Electronics in CY2010 was well publicized. Before that, there were reports of LTE modem development at Renesas Technology. With ST-E, Qualcomm, Renesas all announced the integrated LTE/HSPA+ modem, it would be interesting to see when MediaTek, Spreadtrum, Marvell, Boardcom, MStar, Via, Nvidia are going to go to production with their similar development.

Renesas is no novice to modem technology development. Even before Renesas acquired Nokia's modem team, Renesas had been already working with Nokia to develop their LTE modem chips. There is a long history there. Read the back story here: http://confidential.eetimes.com/news-updates/4233596/Renesas-Mobile-Seeks-to-Be-Qualcomm-Alternative

"Renesas Mobile Corp. announced what appears to be one of the first integrated multimode LTE baseband processors for mobile devices. The MP5232 is a single chip that supports both LTE and HSPA+, aimed at enabling $150-300 devices." According to the press release, this is not only a baseband chip, but instead a SoC solution with integrated application processor (dual-core A9 @1.5 GHz), graphics accelerator etc. "The reference designs presumably include the company’s 1.5 GHz dual-core ARM-based applications processor." According to above, indeed it does, it's built in.

The press release was less than clear, but the way I read it the new baseband is part of a "platform" (i.e. system reference design) that can be paired with an existing apps processor. I have sent questions to Renesas but received no reply yet.

Indeed article above is not having correct information. RMC announced integrated multi mode modem almost one year ago. This platform is having APE integrated with multi mode modem. Details are there on website as well: http://renesasmobile.com/news-events/news/news-20120215-LTE-Triple-Mode-Platform-Optimised-For-Full-Featured-High-Volume-Smartphones.html

Ok, fair enough, might be that I misunderstood this the other way around. In that case, the picture in the press release (http://renesasmobile.com/news-events/news/news-20120215-LTE-Triple-Mode-Platform-Optimised-For-Full-Featured-High-Volume-Smartphones.html) really would be misleading, as it implies the both the baseband and application processor with graphics accelerator etc. are all included within a single "communications processor". Let's see if this gets clarified.

I just updated the story after getting a chance to talk to a RMC exec. Turns out it is an integrated LTE apps processor, similar in some ways to Qualcomm's Snapdragon S4.
