You can select a wide range of core speeds for the Freescale USB micros, ranging from 2.1 MIPS to 410 MIPS. Of course, the high speed cores offer the USB feature only as a very small subset of the total features and peripherals. This possibility makes the Freescale USB products quite versatile, allowing them to find themselves in the most various applications

The Flexis QE128 microcontrollers form the connection point on the Freescale Controller Continuum, where complimentary families of 8-bit S08 and 32-bit ColdFire V1 microcontrollers share a common set of peripherals and development tools to deliver the ultimate in migration flexibility.

Freescale offers many documents for its latest connectivity microcontroller Kirin3, MCF52259. I believe most of the people will start to evaluate the labs without reading the documents. I am one of these guys who hate reading documents. However, it is worth to read the document if you have no experience on CodeWarrior and ColdFire.

The Flexis MCU family represents an additional and important step in the direction of innovation and continuity: it brings to life the Controller Continuum.

It is quite difficult for a designer to select a suitable one from hundreds of microcontrollers for his project.

Generally, the "estimator" is defined as a dynamic system that estimates state variables. There are basically two forms of the estimator implementation: open-loop and closed-loop. In the case of the closed-loop estimator, the error between estimated and measured state variables is used as a correction term to adjust the response of the estimator. The closed-loop estimator is also referred to as an observer.

Car door keypads have traditionally comprised of micro-switches that directly carry the motor currents used to operate windows and mirrors. In the case of electrically operated folding mirrors, a single multiple contact switch unit controls six motors in both directions.

There are too many choices available in the embedded market. In order to develop a good product and release it within schedule, the engineering team has to reply on a mature and affordable platform, or ecosystem. Because the dependency is so tight and system becomes more complex, it is hard to change from one to another. The success or failure for an embedded product has been decided from the very beginning. That is also the reason why Freescale presents MQX solution with Kirin3. However, it is not a bad idea to check out the alternative solutions.
