DETECTING POWER GRID SYNCHRONIZATION FAILURE ON SENSING OUT OF RANGE FREQUENCY OR VOLTAGE
This paper presents the development of a microcontroller based islanding detection for grid connected inverter with very simple under/over voltage and under/over frequency islanding detection algorithms. The system is based on a microcontroller from Atmel 8051 family. The microcontroller monitors the under/over voltage and under/over frequency from utility grid and the processed value of voltage a ....etc

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
