No Preview Available ! Single–Chip Microcontrollers (AMCU) In Brief . . . Motorola offers the most comprehensive selection of high–performance single–chip control systems available from a single source. Microcontroller device families range from industry–standard 8–bit controllers to state–of–the–art 16– and 32–bit modular controllers. Within the price and performance categories of each family, there are a variety of on–chip capabilities to match specific applications. Motorola device families are structured so that upward migration need not involve complete code development. The M68HC11 Family is upward code compatible with M6800 and M6801 software, while the M68HC16 family is source–code compatible with the M68HC11 family. Motorola’s newest 8–bit MCU product line, the M68HC08 family, is fully upward object code compatible with the M68HC05 and M6805 families. In addition, M68300 and M68HC16 devices share standard internal modules and bus configurations.
