Next Generation of Monolithically Integrated Mobile Phone Chip is Optimized for Lowest System Costs and a Five Times Better Performance; And Infineon Offers Ultra-Low Cost Dual SIM Integrated on a Single Platform

Neubiberg, Germany and Macao, China - November 18, 2008 - Today at the GSM Asia, Infineon Technologies AG (FSE/NYSE: IFX) introduced its latest chips for Ultra-Low Cost mobile phones, optimizing the system performance by factor five and also again reducing the bill-of-material (BOM) by almost 10 per cent compared to currently available Infineon platform solutions. Infineon‘s single-chip solution, the X-GOLD™102, enables handset manufacturers to differentiate in the market by providing the lowest cost solutions based on technologies already available in high volume production. The Chip will be provided as part of a platform solution XMM™1020 which encompasses a comprehensive suite of development tools and a support package to customers for shortest time-to-market. This enables customers to bring mobile phones to the market within a time frame of only 5 month compared to the industries usual 10 to 12 month. This pre-tested platform delivers best-in-class RF performance, highest voice quality, well-proven protocol stack, smallest form factor (chipsize: 8mm x 8mm) as well as lowest bill-of-material thereby creating highest customer value and differentiation in the market. The X-GOLD102 single chip includes the baseband processor, the radio frequency (RF) transceiver, RAM memory and the entire power management unit for the mobile phone. It supports MP3 Audio (Basic Multimedia Phone), colour display, FM Radio interface, USB charger and is based on 130nm technology (CMOS SoC) for enhanced monolithic integration. Additionally the XMM1020 platform can be realized in a 4-layer PCB and low via count, in a modem area of less than 5 square centimetres and a component count of less than 50 devices. Dual-SIM XMM™1028 Infineon today also announced its new Ultra-Low Cost Dual-SIM platform. The XMM1028 based on the X-GOLD™102DS and is a cost optimized single baseband solution for Dual-SIM platforms. Negating the need for either a second modem on the platform or complex mechanical switching the XMM1028 provides a fully capable Dual-SIM solution based on a single baseband device. The Infineon XMM1028 reference platform comprises of one Single-Chip that integrates baseband, power management, RF and two SIM interfaces. This allows the user to benefit from the offerings of two Network operators at the same time, without needing to switch the SIM-card. It offers voice call and SMS for both SIM and features unique applications for dual SIM such as Phonebook or Call log. It furthermore allows automatically switching between operators. The XMM1028 platform also needs less than 50 components (Modem) in a PCB mounted area of less than 6 square centimetres and furthermore offers a clean migration path for developers familiar with the XMM1010 platform with fast time-to-market and industries lowest system BOM, which enables manufacturers to offer best possible cost effectiveness in the Dual-SIM segment. Availability of XMM™1020 and XMM™1028 Volume production of the XMM1020 and the XMM1028 has already started.
