The AT24C512 provides 524,288 bits of serial electrically erasable and programmable read only memory (EEPROM) organized as 65,536 words of 8 bits each. The device鈥檚 cascadable feature allows up to four devices to share a common two-wire bus. The device is optimized for use in many industrial and commercial applications where lowpower and low-voltage operation are essential. The devices are available in spacesaving 8-pin PDIP, 8-lead EIAJ SOIC, 8-lead JEDEC SOIC, 8-lead TSSOP, 8-lead Leadless Array (LAP), and 8-lead SAP Packages. In addition, the entire family is available in 2.7V (2.7V to 5.5V) and 1.8V (1.8V to 3.6V) versions.

Java has become a confusing world. Five years ago, there were few decisions to make once you started programming in Java—you used AWT for graphical user interfaces, sockets for network programming, and hacked together everything else you needed. Since then, though, the APIs available for the Java language have grown, and grown. . . and grown. Now you can dabble in Swing, servlets, Enterprise JavaBeans (EJB), JavaMail, and more. Additionally, there are now Packages of APIs, like the Java 2 Micro Edition (J2ME) and Java 2 Enterprise Edition (J2EE). While these Packages seem to be nicely wrapped bundles of useful APIs, they don t help the average developer figure out how to piece together the APIs contained in these Packages. Though it s simple to find documentation on the individual APIs, getting the "big picture" is difficult, at best. One of the most interesting, but difficult, aspects of Java today is building Java enterprise applications using the J2EE package.

High-Speed, Low-Power Dual Operational Amplifier The AD826 features high output current drive capability of 50 mA min per amp, and is able to drive unlimited capacitive loads. With a low power supply current of 15 mA max for both amplifiers, the AD826 is a true general purpose operational amplifier. The AD826 is ideal for power sensitive applications such as video cameras and portable instrumentation. The AD826 can operate from a single +5 V supply, while still achieving 25 MHz of band width. Furthermore the AD826 is fully specified from a single +5 V to ±15 V power supplies. The AD826 excels as an ADC/DAC buffer or active filter in data acquisition systems and achieves a settling time of 70 ns to 0.01%, with a low input offset voltage of 2 mV max. The AD826 is available in small 8-lead plastic mini-DIP and SO Packages.

With the rapid expansion of wireless consumer products,there has been a con- siderable increase in the need for radio-frequency (RF) planning, link plan- ning, and propagation modeling.A network designer with no RF background may find himself/herself designing a wireless network. A wide array of RF planning software Packages can provide some support, but there is no substi- tute for a fundamental understanding of the propagation process and the lim- itations of the models employed. Blind use of computer-aided design (CAD) programs with no understanding of the physical fundamentals underlying the process can be a recipe for disaster. Having witnessed the results of this approach, I hope to spare others this frustration.

Since the first edition of the book was published, the field of modeling and simulation of communication systems has grown and matured in many ways, and the use of simulation as a day-to-day tool is now even more common practice. Many new modeling and simulation approaches have been developed in the recent years, many more commercial simulation Packages are available, and the evolution of powerful general mathematical applications Packages has provided still more options for computer-aided design and analysis. With the current interest in digital mobile communications, a primary area of application of modeling and simulation is now to wireless systems of a different flavor than the traditional ones.

The need to develop reliable microelectronic devices capable of operating at high speeds with complex functionality requires a better understanding of the factors that govern the thermal performance of electronics. With an increased demand on system reliability and performance combined with miniaturization of the devices, thermal consideration has become a crucial factor in the design of elec- tronic Packages, from chip to system levels.
