"Our expanded ColdFire portfolio provides new choices for designers who want affordable, power-efficient industrial USB connectivity", said Mike McCourt, Vice President and General Manager of Freescale's Microcontroller Division.
"Our latest ColdFire USB controllers will allow developers to quickly and easily upgrade their serial applications to USB, helping improve the performance and functionality of their industrial control systems".
ColdFire controllers with USB OTG provide highly integrated embedded control for designers who need cost-effective USB connectivity for industrial control, factory automation, HVAC systems, fire/security systems, point-of-sale equipment and health care monitoring instrumentation.
The ColdFire devices can also be used in consumer applications that require USB connectivity, such as digital cameras, PDAs and PC interfaces.
USB OTG gives developers the option of using the on-chip USB module as a USB device or a USB host.
USB OTG also allows multiple USB devices to communicate without a host interface, making it ideal for system-to-system communication applications.
The ColdFire USB controllers also integrate USB transceivers on chip, which reduces system cost and board space and simplifies system designs based on these devices.
The MCF5221x MCU family provides a cost-effective, single-chip embedded control solution that implements USB 2.0 Full-Speed Host/Device OTG with an integrated USB transceiver.
The MCF5221x family offers a smooth migration to other higher performance ColdFire devices with USB connectivity.
The MCF5253 is a high-performance, cost-effective embedded control solution with High-Speed USB OTG and an integrated USB PHY.
It features 128Kbyte of static random access memory (SRAM), which enables single-cycle access to critical data or control functions.
The MCF5253 also includes an enhanced multiply/accumulate (eMAC) module, which eliminates the need for an off-chip DSP to handle signal processing or filtering tasks.
Freescale's latest ColdFire USB controllers are supported by a comprehensive set of software development tools, including a complimentary Special Edition version of Freescale's CodeWarrior Development Studio for ColdFire, v6.4 or later.
Other professional-grade software tools and operating systems are available through partnerships with world-class suppliers, such as Green Hills Software, Mentor Graphics and Wind River.
Free open-source Gnu tools are available to support the ColdFire product line.
These tools can be downloaded from Freescale's website, and they are also available directly from CodeSourcery.
To help reduce software development cost and time, a complimentary USB software stack from CMX is available for both the MCF5221x family and the MCF5253 device.
In addition, Freescale also offers a uCLinux board support package (BSP) with an integrated USB stack for the MCF5253 device.
MCF5221x and MCF5253 product samples are available now.
Suggested resale pricing for the MCF5221x family starts at US $4.39 in 10,000-unit quantities.
Suggested resale pricing for the MCF5253 device starts at US $8.64 in 10,000-unit quantities.
Evaluation systems for both the MCF5221x products and the MCF5253 device are available now for ordering online.
The M52211EVB evaluationboard is a full-featured development system available at a suggested resale price of US $299.
The M5253EVBE evaluationboard is available now for the MCF5253 for a suggested resale price of US $680.
