FRAM MCUKey Strengths and Applications

Introduction
Ferroelectric Random Access Memory (FRAM) microcontroller (MCU), which features embedded, non-volatile FRAM, is part of the company’s 8-bit microcontroller 8FX family. The new embedded FRAM memory technology can be configured either as Read-Only Memory (ROM) or Random- Access Memory (RAM). The FRAM microcontroller has the added benefits of high-speed programming and low power consumption. The FRAM memory technology, its benefits, applications, to ....etc

LOW-POWER LOW -AREA MULTIPLIER BASED ON SHIFT AND ADD ARCHITECHTURE
Multipliers
Multipliers are among the fundamental components of many digital systems
The largest contribution to the total power consumption in the multiplier is due to the generation of partial product
Among all the multipliers shift and add multipliers are the most commonly used ,due to its simplicity & relatively small area requirement

ABSTRACT
The aim of this paper is to describe the implementation of a lowpower,low-cost 16-bit RISC microcontroller that will act as thecore of a stand-alone security system. The controller is designedto provide moderate-high security at very low cost and to be ableto operate independent of a database. It is designed using 1.5-mSCMOS process from MOSIS and operates at a frequency of 12.5MHz.

Implementing a PID Controller Using a PIC18 MCU


INTRODUCTION
Continuous processes have been controlled by
feedback loops since the late 1700’s. In 1788, James
Watt used a flyball governor on his steam engine to
regulate its speed. The Taylor Instrument Company
implemented the first fully functional Proportional,
Integral and Derivative (PID) controller in 1940.
Although feedback control has come a long way since
James Watt, the basic approach and system elements
have ....etc
