Freescale Strengthens Connectivity in Industrial Applications

Freescale Semiconductor is now offering the new i.MX28x application processor and MCF5441x ColdFire microprocessor families for use in low-power, cost-sensitive industrial applications. Consuming less than half a watt, these devices are ideal for a wide range of applications, including appliances, portable and diagnostic medical devices, energy distribution equipment, meters, human machine interfaces, motor control and industrial controllers, which can benefit from the processors’ extensive on-chip connectivity and analog features, which reduce system-level discrete components, power consumption, board size, development effort and system cost.

The MCF5441x provides customer benefits tailored for motor control, and the i.MX28x offers benefits for display applications. These two processor families introduce an embedded three-port Layer 2 switch that can replace up to $4 of external component cost. Applications such as elevator and assembly line controllers may use this feature to eliminate network equipment and reduce cable costs by daisy-chaining between Ethernet-connected nodes. In addition, both processor families integrate popular cores with dual 10/100 Ethernet ports containing IEEE 1588 hardware timestamp support for accurate clock synchronization of networked devices. These features are combined with many other industry-standard connectivity options, such as multiple UARTs, controller area network (CAN) controllers and USB interfaces to provide system design flexibility.

“Industrial customers typically design systems without cooling fans,” said Bruno Baylac, Freescale’s Director of Global Industrial Segment Marketing. “With all features running at maximum performance, the i.MX28x and MCF5441x families consume less than half a watt of power across the industrial temperature range of -40°C to 85°C. These highly integrated devices give design engineers a low-cost, ultra-low-power solution for a broad range of industrial designs.”

The i.MX28x applications processor family is based on a 454MHz (500 MIPS) ARM 9 core and integrates a rich feature set including: an on-chip display controller with touch screen for a rich user interface; a power management unit to power sequence the device and external components in the system; two USB modules with PHYs; analog to digital converters (ADC); low-power modes for low standby current and secure boot.

The i.MX28x is enabled by Freescale’s i.MX28 evaluation kit, multimedia codecs and complete board support packages for Linux and Windows Embedded CE. In addition, integrated development environments and tool chains, industrial network protocols, additional operating systems, development boards and System on Modules are supported by a vast i.MX ecosystem. The i.MX28x is featured in Freescale’s recently announced Home Energy Gateway reference platform to support the growing smart energy market.

The MCF5441x ColdFire microprocessor family integrates a ColdFire V4 core that offers a high level of connectivity with up to 10 serial ports. Serial connectivity provides designers increased flexibility to meet current and future development needs.

These devices allow designers to reduce system costs with multiple analog peripherals built in to simplify system architecture. Analog features include high-speed precision pulse width modulators and dual high-speed ADCs.

The MCF5441x is supported with a powerful suite of enablement software developed by Freescale, including a board support package for Linux, Freescale’s complimentary full-featured MQX 3.6 real-time operating system, and Eclipse-based CodeWarrior 10.0 IDE. The MCF5441x Freescale Tower System for rapid prototyping completes the offering by providing nearly unlimited quick prototyping capabilities to help eliminate months of development time.
