Introduction 1.2 Welcome to Freescale Medical Solutions Freescale has focused on solving some of the world’s most important technology challenges for over 50 years . Whether the question has been how cell phones can connect people across the world or how to harmonize all of the safety features in a car, Freescale MCUs have been part of the solution . At Freescale we bring that same drive and innovation to the medical industry . The convergence of an aging population and breakthrough technological advances has created endless opportunities for automated medical devices . These devices help ensure the future health of millions of people by providing advances in home health care, clinical activities and medical imaging . Regardless of the end use, developers of medical devices face similar problems . The need to balance processing requirements with power consumption helps to ensure a fast time to market . Navigating the regulatory environment is common with all medical applications . Freescale has implemented a review process which supports life critical applications . At Freescale we offer a wide range of products so that developers can choose MCUs, MPUs, analog and sensor components or RF amplifiers to meet the unique needs of their designs . Developers of medical technology face many challenges today . Freescale believes that having the right silicon should not be one of them . We drive innovations that power next-generation healthcare and medical systems and applications . Our breakthrough thinking, engineering expertise, Medical Center of Excellence, Medical Advisory Board, Product Longevity Program and active membership in the Continua ® Health Alliance demonstrate our commitment to health care . 1.3 Why Freescale? Ecosystems Providing value beyond the responsibility of providing key semiconductor components is paramount . Freescale realizes the need to provide our customers a running start on their next medical design, which is why we embrace one of the strongest ecosystems in the world . Freescale provides the highly trusted MQX operating system free-of-charge to our customers . In addition, our partners on the operating systems side include, but are not limited to QNX Software Systems, Green Hills Software, Mentor Graphics, Wind River, and Windows Embedded . Development tool support is provided by Keil, Micrium, IAR Systems, Windows Embedded, and Linux Systems . Alliance partners also include system developers such as Digi International, our commercialization partner of the Home Health Hub (HHH) reference platform . Cactus Semiconductor Freescale and Cactus Semiconductor, a medical application-specific integrated circuit (ASIC) company, are collaborating to provide customized analog mixed-signal and system-on-chip (SoC) solutions to the medical market . With more than 30 years of combined experience in the medical device market, Freescale and Cactus are focused on providing new generations of smaller, lighter, inexpensive and more efficient medical products that are designed to help improve the quality of life for millions of people . Freescale and Cactus will initially focus on solutions for implantable medical devices, blood glucose monitors and other portable medical applications, such as blood pressure monitors, electrocardiographs and pulse oximetry devices . 6 Medical Applications User Guide
Monebo Kenetic ECG Algorithms Freescale and Monebo Technologies are partnering to offer an ECG-on-a-chip solution that allows customers to choose from more than 300 Freescale MCUs and pair them with the Monebo Kinetic family of ECG algorithms . • Highly accurate Kinetic family of ECG algorithms provide interval measurements, beat classification and rhythm interpretation • Efficient code is ideal for use in embedded applications • Designed to optimize battery life (no “warm-up” period) • FDA 510(k) cleared software allows customers to streamline their regulatory filing • Lowers development cost by providing a tested and validated solution • Scalable solutions based on customer requirements • Optimal design based on the application • Available on the portfolio of products: Kinetis, Coldfire, Power Architecture ® , i .MX S08, and digital signal controllers Medical Specific Reference Designs Freescale understands that reducing time spent on research and development and speeding time to market are key concerns of medical device designers . That is why we strive to produce highimpact design guides in the form of reference designs and application notes . Reference designs give designers access to component configurations that have been proven to work . Application notes prepared by knowledgeable medical doctors and Freescale engineers take the guesswork out of project troubleshooting . Together, these documents offer developers a great jump-start for producing novel designs based on proven concepts . For a full list of Freescale medical reference designs and application notes, visit freescale.com/medical . Development Tools and Software. Learn Once, Use Everywhere. Freescale offers a wide variety of hardware development tools to meet the needs of the medical device designer . Most products feature a cost-effective demo platform for initial evaluation and a full featured evaluation board for advanced development . These products come packaged with CodeWarrior IDE, Freescale developed board support package (BSP), complete documentation, product specific application notes and all the necessary device drivers—everything a designer needs to get started .
