The M68300 Family
The high–performance M68300 family is designed for
embedded control applications. Each M68300 MCU
incorporates a 32–bit M68000–based CPU module (CPU32),
a sophisticated integration module, and a number of
dedicated special–purpose modules. In addition to utilizing a
bus protocol similar to that of the M68020, the system
integration module generates external bus–control signals for
M6800 devices, and provides a variety of programmable
chip–select functions. M68300 devices can be placed in
low–power stop mode to minimize power consumption during
periods of inactivity. The M68300 family provides great design
flexibility, performance, and compatibility with exiting
hardware and software.
