NTT DOCOMO and Partners Develop Platform for HSUPA Mobile Phone

NTT DOCOMO, along with partners Renesas Technology Corp., Fujitsu, and Sharp, outlined plans to jointly develop an SH-Mobile G4 single-chip LSI device and associated platform to support the HSUPA1/HSDPA2/W-CDMA and GSM/GPRS/EDGE (2G) mobile telephony standards. Development of the platform is targeted for completion by early 2010.


The new SH-Mobile G4 will be fabricated with 45-nm process technology and will provide enhanced functionality and improved performance for applications handling HD3 video and 3-D graphics. In addition to HSDPA for fast downlink speeds (max. 7.2 Mbps), the SH-Mobile G4 will support HSUPA to boost uplink speeds to a maximum of 5.7 Mbps.


In 2004 NTT DOCOMO and Renesas began joint development work on the SH-Mobile G series of single-chip LSI devices, which integrate a baseband processor that supports dual-mode communication and an application processor. The SH-Mobile G4 will be the fourth product to emerge from this collaboration.
