MC*-8L family
consisting of proprietary 8-bit, single-chip microcontrollers.
In addition to a compact instruction set, the microcontrollers contain a great variety of peripheral functions such
as timers, a serial interface, a DTMF generator, and external interrupts, making it suitable for circuit control
such as required in telephones.
