This manual introduces Motorola's most comprehensive single-chip controller series, including industry-standard 8-bit controllers, the state-of-the-art 16-bit and 32-bit modular controllers. In each series of price and performance categories, there are a variety of on-chip capabilities to meet specific applications. Motorola's device families are structured so that upward migration does not require complete code development. The M68HC11 series is upward code compatible with M6800 and M6801 software, while the M68HC16 series is source-code compatible with the M68HC11 series. Motorola's newest 8-bit MCU product line M68HC08 series is fully interoperable.
This document serves as a master selection guide for Motorola's Single-Chip Microcontrollers (AMCU). It provides an overview of the company's comprehensive range of high-performance control systems, which span from industry-standard 8-bit controllers to state-of-the-art 16- and 32-bit modular controllers. The guide highlights that these devices are structured to allow upward migration without requiring complete code development.
