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.
