Title: Re-programmable flash memory micro controller as programmable logic controller

Abstract: Functions of a programmable logic controller are located in physically separable units. These physically separable units include a program execution device, or control device, whose function is limited to sequencing through the user logic program and a communication/programming device, which provides the programmability function. The micro controller incorporates a micro processor, RAM, and a re-programmable Flash EPROM in a single package implements the logical core of the program execution device.
