                  TIs third-generaTIon GSM-based soluTIons for the Ultra
                  Low-Cost (ULC) Handsets
                  Leveraging an advanced 65-nm process with TMS320C54x™
                  DSP and ARM7 cores in the same package, the TCS2315 GPRS
                  solution integrates TIs breakthrough digital RF DRP™
                  technology to offer the most compelling user experience in
                  Ultra Low-Cost (ULC) handsets. Part of the LoCosto ULC family,
                  the TCS2315 enables handsets with high performance, robust
                  functionality and innovative form factors in the most
                  price-sensitive handsets. Ideal for emerging markets such as
                  India, China, Russia and Brazil where the next billion
                  subscribers will come from, the scalability and flexibility of
                  the TCS2315 LoCosto ULC GPRS chipset also allow it to be
                  deployed in enhanced handsets for value-conscious segments in
                  more mature markets.

                  Software portability from one generation of LoCosto solution
                  to the next gives manufacturers and operators the ability to
                  rapidly and cost-effectively differentiate handsets and
                  service offerings for both emerging and mature markets,
                  crossing over regional borders, language barriers and
                  subscriber requirements.
                  A set of enhanced capabilities are now possible in ULC
                  handsets, such as a relatively high-resolution color display
                  without requiring additional external SRAM, VGA camera
                  support, MP3 playback and mass storage (SD/MMC), USB and
                  Bluetooth® connectivity, high-end full duplex voice
                  quality, a MIDI player with 32 polyphonics, MP3 and polyphonic
                  ringers, longer talk time and standby time, stereo FM radio
                  connectivity, USB charging, handsfree speakerphone operation,
                  vibration ringer, headset support and other functionality.
