In consumer electronics, telecommunications and
industrial electronics, there are often many similarities
between seemingly unrelated designs. For example,
nearly every system includes:
· Some intelligent control, usually a single-chip
microcontroller
· General-purpose circuits like LCD drivers, remote I/O
ports, RAM, EEPROM, or data converters
· Application-oriented circuits such as digital tuning and
signal processing circuits for radio and video systems, or
DTMF generators for telephones with tone dialling.
To exploit these similarities to the benefit of both systems
designers and equipment manufacturers, as well as to
maximize hardware efficiency and circuit simplicity, Philips
developed a simple bi-directional 2-wire bus for efficient
inter-IC control. This bus is called the Inter IC or I2C-bus.(In consumer electronics, telecommunications and industrial electronics, there are often many similarities between seemingly unrelated designs. For example,
