Freescale Semiconductor's latest line of i.MX application processors takes the connectivity, touch control, security and cost-saving integration capabilities of a wide range of industrial applications and in-vehicle infotainment applications to a new level. The i.MX25 family based on the ARM9TM core is Freescale's first-line application processor that integrates a liquid crystal display (LCD) and touch screen controller, DDR2 memory support, controller area network (CAN), Ethernet and USB connectivity. High-level on-chip integration minimizes the need for additional discrete components and shrinks board space, ultimately reducing development and product costs. The low-power i.MX25 portfolio includes five products (three for industrial and general-purpose embedded designs and two for automotive applications).
i.MX258 is a third-party industrial device for the industrial security market. The processor comes with an on-chip security engine and is ideal for security product development. If a device only needs to run barcode software on itself, then such a security engine is very important. Because when the device is detected to be threatened, a specific tamper-proof detection circuit can quickly erase the above confidential information. The security and connectivity of the i.MX258 processor provides a stable and cost-effective solution for point-of-sale (POS) systems.
The i.MX258 application processor based on Freescale's ARM926EJ-STM is designed for industrial and general purpose embedded applications where extreme security is required. The i.MX258 includes an on-chip security engine that is ideal for creating highly secure devices. This product is critical for programs developed specifically for such devices and running on such devices. Freescale has designed a unique Tamper Detection circuit that quickly removes confidential information when it detects a device threat. The i.MX258's security features and interfaces provide a powerful yet cost-effective solution for point-of-sale systems, biometrics, and secure residential gateways such as smart meters. 
Key features and benefits of the i.MX258 processor include:
ï³ 400MHz ARM926EJ-S core 10/10 10/100 Ethernet MAC with RMII support
两个 Two on-chip USB ports with PHY
- High Speed ​​USB OTG with HS PHY
- High Speed ​​USB Host with FS PHY
128 128KB on-chip SRAM for low power LCD refresh
ï³ 3 universal 12-bit ADC channels 触摸 touch screen controller ï³ two CAN interfaces ï³ two smart card interfaces ï³ enhanced serial audio interface ï³ external storage interface:
- 16-bit 1.8V mobile DDR and DDR2
- 16-bit 3.3V SDRAM
- 8-/16-bit NAND or NOR
ï³ 3.3VI/O Reduces the number of external components 增强 Enhanced security features including tamper detection of voltage, frequency and temperature
ï³ High-Assurance Boot (HAB)
The i.MX251 and i.MX255 application processors are tailored for in-car infotainment systems. Such systems require the many features of a high-end infotainment system while at the same time striving to avoid excessive costs. Freescale's devices have met all the requirements of the AECQ-100 automotive certification.
The i.MX253 and i.MX257 application processors offer flexible connectivity options for a wide range of industrial designs that require LCD and touch screen support. These applications include residential smart meters, graphical keyboards and security panels, human interface (HMI) designs, barcode scanners, factory automation and robotics, and printers.
Paul Marino, general manager of Freescale's multimedia applications division, said: "Freescale's i.MX25 family is designed to help embedded designers avoid new connections, touch screens, DDR2 memory and security in their applications. The cost of our current high-performance on-chip integration and software development support can help industrial and automotive customers develop more cost-competitive products while accelerating the speed at which new products are available."
About the i.MX25 Application Processor Family The i.MX25 application processor offers a variety of connectivity and feature set options for developers of industrial and automotive applications. This on-chip integration helps reduce system complexity and cost, enables developers to create lower-level products, provides high-end platform-based, but cost-sensitive market usage, or further upgrade existing ones by adding more features. Level solution.
Development Tools and Software To help developers accelerate new products, Freescale offers powerful development tools and software support for the i.MX25 application processor family. The i.MX25 Product Development Kit (PDK) is an integrated hardware and software solution that simplifies product development, allowing developers to focus on how to develop product differentiation for greater market success. The i.MX25 Product Development Kit (PDK) provides comprehensive board support for Linux® and Windows® embedded CE operating systems.
It is reported that the next "Freescale Charging Bar" event, which will be held on December 23 (10:00-12:00), will be delivered by Chen Gang, senior application engineer of Freescale System Solutions. He will share the latest two touch sensor solutions from Freescale's latest touch sensor solutions with "Smarter Touch - Freescale's Best Touch Sensing Solution for Your Design", showing how to simplify portable low Touch applications for power products and how to provide a cost-effective and flexible solution for human-machine interfaces.
