S5P644

Samsung Electronics Co. Ltd has unveiled its latest ARM11 application processor, the S5P6440. Designed using its 45nm low-power CMOS process technology, the S5P6440 offers a low-power, high performance and cost-effective solution for consumer electronic products such as personal navigation devices (PNDs).

"Today's ultra-competitive consumer electronics market demands rapid performance upgrades and effective cost reduction to continue its expansion," said Kwang-hyun Kim, senior VP of sales and marketing at Samsung Electronics' system LSI division. "Our S5P6440 application processor is specifically designed with those objectives in mind to offer improvements in CPU performance at low power, high quality graphics capability and lower system BOM cost."

Samsung's S5P6440 is based on an ARM1176 CPU core, which runs at either 533MHz or 667MHz clock speed. The CPU core and all on-chip hardware accelerators and peripheral interfaces are connected through a 64bit AXI bus running at 166MHz, allowing ample input/output bandwidth for handling the multiprocessing requirements in real-life applications. The S5P6440 features 2D graphics acceleration hardware that is compliant with the OpenVG API standard. The OpenVG API standard enables advanced graphics functions such as alpha blending for transparency effects, anti-aliasing for sharper graphics and vector graphics support for scaling without loss of image quality. Using this graphical capability, devices implemented with the S5P6440 can offer a graphical user interface that enhances the user experience.

To lower the system BOM cost and ease the design complexity, the S5P6440 incorporated various interface hardware IP. An advanced NAND error correction hardware is included to support current and next-generation MLC NAND flash devices. The S5P6440 also integrated a DRAM memory controller that supports both mobile DDR (mDDR) and the lower cost DDR2 memory chips, allowing device manufacturer's different choices of storage device types to meet different market segments' requirements.

In addition, the S5P6440 integrated a mobile industry processor interface (MIPI) display serial interface (DSI) for advanced graphics and display capabilities at low power.

The MIPI DSI interface can help customers reduce the complexity of the display interface by reducing the number of pins, which has benefits in terms of design simplicity and cost. MIPI DSI also uses a differential signal that substantially reduces EMI issues. These advantages are increasingly important for mainstream connected CE products where noise interference among electronic components in within a product can adversely affect the product's performance.

The S5P6440 application processor supports all major high-level operating systems including WinCE and Linux. This allows OEMs and PND manufacturers to differentiate their products through an easy-to-use, customizable user interface and robust, flexible application architecture.

The S5P6440 application processor is sampling to key customers now and is scheduled for volume shipment in the Q3 09. The chip is housed in a 13 x 13 FBGA package with a ball pitch of 0.65mm.
