The latest Flash MCUs from Motorola offer typically 100,000 write/erase cycles and 50-year data retention.
The devices also offer a suite of connectivity and performance enhancement features that are ideal for multifunction applications.
The MCF5227x devices' high level of integration helps reduce the cost and complexity of developing a wide range of commercial and industrial operator interfaces.
Applications for these processors include building/home automation, HVAC and lighting control systems, fire/security control systems, medical and patient monitoring products, test and measurement equipment, point-of-sale (POS) systems and large appliances (cookers, refrigerators and washing machines).
"Freescale's feature-rich MCF5227x LCD processors are ideal for embedded developers who want to 'add touch' to their commercial and industrial control interfaces", said Aiden Mitchell, Consumer and Industrial MCU Product Manager for Freescale's Microcontroller Solutions Group.
"In addition to integrating touch-screen-based LCD functionality, these ColdFire devices offer outstanding price/performance and versatility, backed by the most comprehensive 32bit development ecosystem in the embedded industry.
The MCF5227x processors are equipped with an integrated controller area network (CAN) module and a universal serial bus (USB) host, device and On-the-Go (OTG) module.
These on-chip connectivity options give developers the flexibility to standardise or upgrade their serial communications.
Developers can leverage CAN connectivity to address industrial reliability requirements.
USB OTG provides an easy way to input data to or collect data from a system.
To enhance the performance of multifunction systems, the MCF5227x devices feature a flexible external bus and a serial boot flash capability.
When combined with the devices' 128Kbyte SRAM block, the boot flash capability makes it easy to store code in the serial Flash memory.
In addition to enhancing system performance, the 128Kbyte SRAM block helps reduce the need for external memory.
The external bus also is designed to reduce system cost by enabling a variety of cost-effective external memory configurations, including support for DDR.
Freescale's MCF5227x LCD processors are supported by a set of software development tools, including a complimentary Special Edition version of CodeWarrior Development Studio for ColdFire Architectures V7.0.
The Processor Expert rapid application design tool is integrated into the CodeWarrior Development Studio, enabling developers to define application functionality and generate tested code in a graphical environment.
Additional professional-grade software tools and operating systems for the MCF5227x devices are available through partnerships with world-class suppliers.
Freescale also offers a variety of open-source software tools designed to help MCF5227x customers reduce application development costs.
These Linux OS-based tools include a uCLinux board-support package (BSP) with support for NanoX, an open-source GUI development software solution.
The BSP also includes driver support for key peripherals, including USB, touch-screen control and CAN.
To help developers explore the features and capabilities of MCF5227x processors, Freescale offers the M52277EVB evaluation system, a full-featured platform that includes a development board and a 3.5in LCD touch panel designed to enable quick evaluation of the devices' LCD and touchscreen features.
The M52277EVB system also includes an interactive DVD with tools, software examples, walk throughs and lab supplements.
