Marvell is showing off a bunch of new chips for smartphones, smart TVs, networking, and other gear at the Mobile World Congress event this week. Among the new products is the world’s first TD-HSPA+ modem chip for smartphones used in emerging countries such as China.

Mobile chip makers are dueling to get their chips designed into the latest smartphones and tablets at this week’s event, which is being covered live by VentureBeat’s Devindar Hardawar. Nvidia, Qualcomm, and Intel have all announced big customer wins already at the show.

The new modem chip, the Marvell PXA1202, can triple the data rate for phones connected to TD-SCDMA networks. Phones using the so-called 3.5G technology can download data at rates of 8.4 megabits per second, compared with 2.8 megabits per second for current phones.

Marvell is also launching its LTE multimode modem chip set for phones that can transfer a lot of data at a low cost. The new PXA1802 chip will help address geographic fragmentation problems that have slowed adoption of certain mobile standards. The chip targets China’s TD-SCDMA network technology for mobile phones.

Marvell said it will have a number of new handset design wins for its TD-SCDMA chips for emerging markets such as China. Those designs use a user interface from Marvell dubbed Kinoma.

Kinoma Play is a user interface for smartphones, tablet computers, and other mobile devices. It can be built into a single application or become the user’s main interface for operating the multimedia apps on a phone. Kinoma Play is functional, fluid and fast interface. It works great with a touchscreen, letting you do tasks more easily, such as flipping through your music collection or zooming in on a face in a picture. Marvell acquired the small software company Kinoma last year.

Among Kinoma’s new features: the ability to manage your home appliances and lighting from afar. It makes sense for a chip maker to do this because it isn’t all about the hardware. Great smartphone software can show off the power of a chip through applications such as photo browsing. Intel has learned that too and is designing entire phones for its first smartphone customers.

“I am very proud that we are a strong driving force behind the evolution of the smart devices people around the world use every day in the home and at work, from mobile smartphones and smart TVs, such as Google TV, to smart appliances, energy-efficient lighting and mobile printing,” said Weili Dai, co-founder of Marvell.

Marvell’s new WiFi platform, Avastar, will be upgraded to handle 802.11ac, which promises much faster wireless networking in the not so distant future, as well as near-field communications (NFC) for more ubiquitous phone-based payment platforms.

Marvell said it is also launching technology to support easier mobile printing via WiFi networks.
