Did you know that you could implement I2C function-
ality using the Intel MCS-51 family of microcontrol-
lers? The I2C-bus allows the designer to implement in-
telligent application-oriented control circuits without
encountering numerous interfacing problems. This bus
simplicity is maintained by being structured for eco-
nomical, efficient and versatile serial communication.
Proven I2C applications are currently being implement-
ed in digital control/signal processing circuits for audio
and video systems, DTMF generators for telephones
with tone dialing and ACCESS.bus, a lower-cost alter-
native for the RS-232C interface used for connecting
peripherals to a host computer.
