LoCostoULCSingle Chipfamily: TIs third-generationGSM-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 digitalRFDRP" 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 overregional 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.

Equipped with TIs scalable and hardware-based M-Shield" security technology, a TCS2315 handset offers ironclad protection of the owners personal information. M-Shield also prevents the unlocking of the handsets SIMlock code, defeating attempts to switch networks. High-value content and IP can be fully protected from tampering, piracy and malicious attacks.
