Basic 8051 Core Microcontroller Interruptions

The person who is contacted must usually stop what they are doing and respond to the request of the person that needs to be answered. Afterwards, the person who has been called must return to what they were doing. This same approach has also been implemented in computer systems, for instance, when a transducer (electrical/electronic circuit with a sensor) that is electrically connected to one of its interruption inputs requests an action from the computer system. Therefore, the computer system must stop what it is doing, answer the call of the interruption, and finally resume what it was doing. This strategy of input variable monitoring greatly facilitates the use of microcontrollers in machine control applications [1–10].

This special function register is able to provide the conditions of the processing of the last instruction performed, which is capable of changing it (only some instructions can modify it). It is used by the decision-making instructions to implement control and management software of machines, processes, and tasks to be performed [1–10].

Built by Intel in the 1980s, this project incorporated new features from many other manufacturers (Texas Instruments, Atmel, Philips, Analog Devices, Infineon, etc.), making even more fans. Boosted by its success in the 1990s, this project has caused a true revolution in the field of portable programmable electronic equipment projects This microcontroller is currently used in implantable medical devices (IMD) and in embedded systems for cars, trains, airplanes and aerospace applications, motivating the author to reformulate the book entitled 8051-Core Microcontrollers. This book, whose title is "8051-Core Microcontrollers-Fundamental Concepts and Exercises," describes the basic concepts of the 8051-core microcontroller hardware and software, as well as some examples of applications, which can be used in the free simulators/compilers and low-cost kits. It is divided into nine chapters and an appendix (detailed instructions set). The first chapter presents the basic and fundamental concepts for the understanding of computer systems based in microprocessors/microcontrollers. The second chapter highlights the 8051-core microcontroller hardware. The set of instructions and addressing modes are described and discussed in the third chapter. Chapter 4, considered the most important, explains in detail how a software designer of computer systems should proceed to implement a software project regarding a simple and systematic way, using the flowchart design tool. The author thoroughly presents and discusses the definition, how the subroutines work, and how they can be used in the structuring of the assembly programming language for the implementation of computer systems, so that the reader may become a software designer. The input and output interfaces and how to manipulate the variables of a computer system based in 8051-core microcontrollers are described in Chap. 6. In Chap. 7, the interruptions of the 8051-core microcontroller are presented, and some examples of applications are given and discussed.

LCE and PAMDLE Effects From Diamond Layout for MOSFETs at High-Temperature Ranges

These effects are capable of boosting the electrical performance of analog MOSFETs in relation to that of the standard MOSFET (rectangular gate shape). First, we have developed an experimental comparative study between MOSFETs implemented with the hexagonal layout style diamond MOSFET (DM) and its rectangular MOSFET (RM) counterpart, regarding that they present the same channel width and gate area, operating in a wide high-temperature range (from 300 to 573 K). These devices were manufactured with the technology of bulk complementary MOS (CMOS) integrated circuits (ICs) of 180 nm. The experimental results have shown that DM has obtained a better electrical performance of analog MOSFETs than the one observed in RM counterpart (for example, gains of 67% for saturation drain current and 90% for the transconductance), regardless of temperatures in which they were exposed. 3-D numerical simulations were used to justify the better electrical performance of DMs due to the LCE and PAMDLE effects, in relation to one of the RM counterparts, by observing the behavior of electrostatic potentials, longitudinal electric fields, and drain current densities of the devices as the temperature increases. Besides, a study about the short-channel effect has shown that DM can suppress this effect more effectively than RM at room temperature due to a smaller reduction in effective channel length of DM.

There are several ways to try to achieve these goals, among them are the use of new materials for the manufacture of semiconductor devices, new planar and threedimensional structures of MOSFETs and new manufacturing processes. Another innovative and fully-Brazilian alternative is the use of new and different layouts for the implementation of these devices. Among the different layouts proposed, we have the ellipsoidal that is the evolution of other layouts, such as the hexagonal and the octagonal. Recently, experimental studies on the advantages and disadvantages between the ellipsoidal layout MOSFET and its corresponding rectangular were conducted showing promising results for this new layout. The main idea of diamond and ellipsoidal layouts was to take advantage of the cornering effects to potentiate the...

Using the Octagonal Layout Style to Implement the Pass MOSFET to Improve the Electrical Performance of the CL–LDO Voltage Regulator

This study regards the use of an octagonal layout style in the pass device MOSFET of a CL–LDO VR to mainly boost its open-loop voltage gain and reduce output impedance. The results show that this innovative layout approach used in the CL–LDO voltage regulator can increase its power supply rejection ratio (PSRR) in approximately 2 dB (60 Hz), without degrading its quiescent current (Iq) (improvement of 2% better), and without wasting additional die area, in comparison to the one that its pass MOSFETs was implemented by using standard rectangular layout style. The 130 nm Bipolar Complementary Metal-Oxide-Semiconductor (BiCMOS) manufacturing process from GlobalFoundries was used to implement both CL–LDO VRs, via MOSIS Educational Program. The die areas of each CL–LDO VRs are the same and equal to 0.00994mm2.

These innovative layout styles are based on pn junctions engineering between the drain/source and channel regions or simply MOSFET gate layout change. These interesting layout structures are capable of incorporating new effects in the MOSFET structures, such as the Longitudinal Corner Effect (LCE), the Parallel connection of MOSFETs with Different Channel Lengths Effect (PAMDLE), the Deactivation of the Parallel MOSFETs in the Bird's Beak Regions (DEPAMBBRE), and the Drain Leakage Current Reduction Effect (DLECRE), which are still seldom explored by the semiconductor and CMOS ICs industries. Several three-dimensional (3D) numerical simulations and experimental works are referenced in this book to show how these layout techniques can help the designers to reach the analog and digital CMOS ICs specifications with no additional cost. Furthermore, the electrical performance and ionizing radiation robustness of the analog and digital CMOS ICs can significantly be increased by using this gate layout approach.
