Another name for Chip, an IC is
a small electronic device made out of a semiconductor material. The first integrated
circuit was developed in the 1950s by Jack Kilby of Texas Instruments and Robert Noyce of
Fairchild Semiconductor.
Integrated circuits are used for a variety of devices, including microprocessor audio and
video equipment, and automobiles. Integrated circuits are often classified by the number
of transistors and other electronic components they contain:
* SSI (small-scale integration): Up to 100 electronic components
per chip
* MSI (medium-scale integration): From 100 to 3,000 electronic
components per chip
* LSI (large-scale integration): From 3,000 to 100,000
electronic components per chip
* VLSI
(very large-scale integration): From 100,000 to 1,000,000 electronic
components per chip
* ULSI
(ultra large-scale integration): More than 1 million electronic components per
chip
There are two major kinds of ICs:
* analog (or linear) which are used as amplifiers, timers and oscillators
* digital (or logic) which are used in microprocessors and memories
Some ICs are combinations of both analog and digital.
All ICs have orientation. |
