In a previous article we have seen the basic concepts related to the CRC (Cyclic Redundancy Check) calculation and its importance in providing a protection against accidental data corruption. Scope of this article is to show how those concepts have been applied on a commercial microcontroller family: the Flexis AC by Freescale.

The timing capacitor, or "buffer" capacitor, is the third important element to be considered in designing a vibrator power supply.

This article presents the hardware and software design of a low-cost V.21/V.22/V.22bis soft modem.

Here are some more I/O specific techniques for static consumption. Try reducing the switch capacitances and frequencies of I/Os, decouple I/Os when you're in the sleep mode.

In this article we will discuss the advantages of Digital Potentiometers comparing with the Conventional Mechanical Potentiometers.

This is EMCelettronica's tribute for Michael Jackson King Of Pop. God bless you!

Freescale PowerQUICC® III family of processors has imposed itself as the leading solution for communication systems, becoming a reference point for the wireless, networking, and switching fields of application.

The IR3820 is a synchronous buck converter that combines high performance with small size providing a flexible solution in a small 5mmx6mm Power QFN package.

Think Small - Small Power, Small Cost, Small Price MCF51CN from Freescale

Horizontal motion allows the programmer to move any of the 5 graphics objects relative to their current horizontal position. Each object has a 4 bit horizontal motion register (HMPO, HMP1, HMM0, HMM1, HMBL) that can be loaded with a value in the range +7 to -8 (negative values are expressed in two's complement form).

This article provides an overview of the sources of FPGA power dissipation, design practices that can help reduce consumption and thus junction temperature, how to estimate and analyze power, and then some tips for managing a variety of power sources required for an FPGA implementation.

Competition in the semiconductor market is quite high, and one of its most diverse branches is the microcontroller market.
