Did you know that you could implement I 2 C functionality using the Intel MCS-51 family of microcontrollers? The I 2 C-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 economical, efficient and versatile serial communication. Proven I 2 C applications are currently being implemented 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.
