NEC FOMA N902i Mobile Phone Now Features LCD Driver IC with Mobile CMADS
Mobile phone technology is advancing faster than ever, and LCD driver ICs are a key device in this trend.
Here's a look at NEC Electronics' highly competitive product technologies and their advantages for users.
World's first in mass production(*1)
The NEC FOMA N902i mobile phone now includes an NEC Electronics LCD driver IC with Mobile CMADS (Mobile Current Mode Advanced Differential Signaling), which features a high-speed serial interface for mobile applications. These new mobile phones have been on the market since November 2005. This high-speed serial interface for mobile applications is built into the LCD driver IC. In the field of mobile devices that includes mobile phones, the NEC FOMA N902i mobile phone is the world's first mass produced product that features the Mobile CMADS driver IC.

Advantages of Mobile CMADS
- Fewer data transmission lines
One issue that faced the developers of the advanced multi-function FOMA N902i mobile phone was the increasing number of parts around the LCD module, packed so tightly as to leave no gaps in between, which made it difficult to find space for LCD module connections. However, by using a LCD driver IC that includes the Mobile CMADS high-speed serial interface for mobile applications developed by NEC Electronics, the key feature of requiring fewer transmission lines has been realized, and this has made more space available for the required connections.
- EMI noise
As for the ever-present development issue of EMI noise in mobile phone transmissions, ever since the prototype stage of the FOMA N902i, developers reported success in lowering EMI noise levels compared to those of parallel interfaces.
Popular from the start
The NEC FOMA N902i mobile phone has been well received by consumers since its November 2005 market debut.
Mobile CMADS is a registered trademark of NEC Electronics Corporation in Sweden, UK, Finland, Spain, and Germany or a trademark in Italy, Taiwan, South Korea and China.
