By reducing both power consumption and device part costs, while delivering high-resolution VGA graphics, the new product will help designers meet two of the most important goals in the competitive mobile market.
Various techniques are available to reduce component costs and power consumption in mobile devices. For example, in the current generation of mobile phones, the application processor accounts for a significant part of both cost and power consumption. With the trend toward higher resolution, the application processor must integrate more memory for graphics data, which increases the size and cost of the chip. The application processor also requires a continuous supply of power in order to transfer the data to the LCD panel. By inserting the new chip between the application processor and an LCD driver IC, designers can choose a less costly application processor and implement new power saving strategies, thus reducing the overall system cost and power consumption.
With its 8 megabits of eDRAM memory and integrated graphics logic, the new chip is an innovative solution from NEC Electronics, the industry leader in eDRAM technology. Since introducing its first unique eDRAM products for the 180-nm process, NEC Electronics has shipped more than 100 million eDRAM products, winning a high reputation for reliability and technological excellence. NEC Electronics intends to continue to expand its lineup of eDRAM products for mobile and other applications.
