Matsushita Electric Industrial Co Ltd developed the "MN2CS0038" (nicknamed the UniPhier 4MBB+), a mobile phone LSI based on its "UniPhier" digital audio/visual equipment platform, and announced that it would start shipping samples in late July 2008.
In addition to the communication function, the new LSI integrates application functions such as graphics rendering, 1seg reception and audio/visual content playback into a single chip. The LSI was manufactured by using the 45nm process and is composed of 280 million transistors.
Compared with the company's existing product, the MN2CS0038 reportedly reduces the power consumption of a mobile phone by approximately 25% and the footprint by about 40%. The communication function supports 7.2Mbps W-CDMA/HSDPA and GSM/GPRS standards.
The operating frequency of the application processor is approximately 1.7 times higher than that of the existing product. The LSI facilitates the migration of existing game content, because the audio/visual playback function supports the 2D/3D graphics standard "OpenGL ES1.1," the company said.
Compared with the existing product, the 1seg viewing time and the playback time of various kinds of audio content are reportedly extended by 25%. The power consumption was reduced by controlling the operating frequency and the threshold voltage in accordance with the types of application and communication, as well as by employing the optimum power control architecture, the company said.
Furthermore, the company adopted its proprietary memory architecture where one unified external memory is shared by the communication and application processings, which otherwise require individual memories. As a result, the number of memory chips required is halved, thereby reducing the size of mobile devices.
The supply voltage of the I/O circuit is 1.8V and that of the internal circuit is 1.2V. The operating frequency is 500MHz. The LSI supports the coding and decoding of MPEG-4, MPEG-4 AVC/H.264 and JPEG audio/visual data.
The MN2CS0038 also supports the decoding of VC-1 content (VC-1coding is not available). It is provided in a 563-pin plastic chip size package (PCSP) with the PoP structure.
The company has already developed a UniPhier-based LSI for use in digital TVs.
