Microcontroller families introduced by Motorola Semiconductors (later Freescale Semiconductors, and currently NXP Semiconductors): 68HC05, 68HC08, 9S08, 68HC11, 68HC12, 9S12, and 68HC16. Specify your particular type in question, as the differences between particular chip are big enough to mislead possible answers.
