This high-performance, power efficient processor is a fully integrated baseband solution that features Intel XScale microarchitecture and Intel® Micro Signal Architecture (Intel® MSA). The integraton of on-chip flash memory and SRAM greatly increases processing power while reducing power consumption. The Intel PXA800F cellular processor enables development of powerful, cost-effective wireless devices capable of running rich data applications. It includes a development platform for a full-featured quad-band voice/data handset that is scalable across multiple tiers.
This manual provides a high level overview of the subysytem features, detailed architecture and signal descriptions, memory and register mappings, and supported RF interfaces that should aid designers in developing cellular handsets with the Intel PXA800F cellular processor. Application developers should use this manual to gain a better understanding of the GSM/GPRS baseband implementation, while validation engineers should use it as an aid for creating functional tests.
Product Description
Developed by Intel and manufactured on Intel"s industry-leading 0.13 µm flash + logic process technology, the Intel® PXA800F Cellular Processor is a fully integrated cellular and application processor that is at the heart of an advanced total system solution for today"s GSM/GPRS mobile phones. This high-performance, power-efficient processor integrates Intel® XScale™ technology with Intel® On-Chip Flash memory and the Intel® Micro Signal Architecture delivering class-leading performance, with industry-leading application headroom for voice and computation-intensive data applications for mainstream mobile phones.
The Intel PXA800F cellular processor is the first product to fully integrate a GSM/GPRS baseband solution with a high-performance application processor and Flash memory on a single chip. This solution features an Intel XScale technology-based processor capable of running at up to 312MHz, in addition to the Intel Micro Signal Architecture, a dual-MAC signal processor core, that can run at 104MHz. Integration of Intel On-Chip Flash memory and SRAM into the processor yields both a significant increase in processing performance and a reduction in power consumption. This design enables the development of powerful, cost-effective wireless devices capable of running rich data applications. This single-chip product is part of a system solution that includes a development platform for a full-featured quad-band voice/data mobile handset that is scalable across multiple product tiers.

Intel® Personal Internet Client Architecture
The increasing availability of mobile content and the emergence of worldwide wireless data standards are driving the development of a new generation of data-enabled wireless devices for businesses and individuals. To address this need, Intel has defined an architectural framework, the Intel® Personal Internet Client Architecture (Intel® PCA) that promotes the rapid development and deployment of next-generation wireless devices, applications and services. It streamlines the development process by enabling software and hardware developers to design to an open environment for true application scalability. The rapid deployment of wireless products with new and compelling applications will be the key to making cellular data networks successful. By offering integrated, scalable solutions with an open development environment, the Intel PXA800F cellular processor will play a leading role in transitioning the wireless market to an applications focus.

Reference Software
The reference software resides entirely in on-chip flash memory. It implements the physical layer and protocol layers 1, 2, and 3 required for full phase 2+ GSM/GPRS Class 12 functionality. Intel provides the physical layer and protocol layer 1; the protocol layers 2 and 3 are available from TTPCom*, a leader in GSM/GPRS software development. Alternatively, developers can opt to utilize their own layer 2/3 solution. Other software available includes a generic MMI, SIM application toolkit, SMS, EMS, MMS, HSCSD, USB client, network-based Position Location, and multiple vocoders (FR, EFR, HR and AMR). Support is also provided for voice recognition, voice record/playback, battery charging, Bluetooth, G3 Fax, WAP, MP3 decoder, MPEG-4 decoder, and dual SIM interface. The software development environment also includes an optimized C/C++ compiler for the Intel XScale core.
