Innovative ConvergenceTM Platforms
i.250-21
Overview Building on the success of the industry-leading i.250 Innovative ConvergenceTM (2.5G) platform, a silicon-to-software solution for wireless handsets, Freescale Semiconductor* offers an enhanced platform that provides advanced features and applications in the Global System for Mobile Communications (GSM)/General Packet Radio Service (GPRS) arena. The i.250-21 Innovative Convergence platform is designed to support 850 MHz and 900 MHz GSM, 1800 MHz digital communication services (DCS), and 1900 MHz personal communication services (PCS) wireless networks. This quad-band operation allows handsets based on the i.250 platform to work in virtually any 2.5G GSM/GPRS wireless network in North America, Europe and Asia. The i.250-21 platform is flexible and scalable: It is designed to support the high-volume production of entry-level voice and data phones as well as the use of higher-tier feature sets; and it provides a seamless migration path to next-generation technology. The i.250-21 platform offers manufacturers a solution to build products that are compact, cost-effective, secure, and can be delivered to market quickly. Platform Chipset Features

Enhanced Security
GPS RF front-end IC to the i.250-21, and licensing the SiRFLoc client software directly from SiRF Technology, Inc., the i.250-21 customer has a complete AGPS solution that is capable of supporting the E-911 U.S. government mandate as well as a broad suite of location-enabled applications where size, cost and performance are critical. In addition, Freescale will offer a GPS hardware reference design and interface software to simplify the integration of this optional GPS functionality. Platform Development Environments The i.250-21 platform is designed to simplify the development process for a GSM/GPRS product by organizing the tools and different pieces of the solution into the following three major development environments: > Integrated development environment (IDE) for software and man-machine interface (MMI) development * Application Development System (ADS) * Software--GSM engine with GPRS and MMI toolkit * Supporting tools for handset development > Radio Test Environment (RTE) for radio development and performance optimization * Flash loader tool * Radio tuning tool > Manufacturing Test Environment (MTE) for meeting type approval and production line test requirements * Test planning Innovative Convergence For more information about Freescale's Innovative Convergence products and wireless solutions, visit www.freescale.com/i250. *The Semiconductor Products Sector of Motorola, Inc. became Freescale Semiconductor, Inc. in 2004.
