1.4 MC68HC000
The primary benefit of the MC68HC000 is reduced power consumption. The device
dissipates an order of magnitude less power than the HMOS MC68000.
The MC68HC000 is an implementation of the M68000 16/-32 bit microprocessor
architecture. The MC68HC000 has a 16-bit data bus implementation of the MC68000 and
is upward code-compatible with the MC68010 virtual extensions and the MC68020 32-bit
implementation of the architecture.
1.5 MC68HC001
The MC68HC001 provides a functional extension to the MC68HC000 HCMOS 16-/32-bit
microprocessor with the addition of statically selectable 8- or 16-bit data bus operation.
The MC68HC001 is object-code compatible with the MC68HC000, and code written for
the MC68HC001 can be migrated without modification to any member of the M68000
Family.
1.6 MC68EC000
The MC68EC000 is an economical high-performance embedded controller designed to
suit the needs of the cost-sensitive embedded controller market. The HCMOS
MC68EC000 has an internal 32-bit architecture that is supported by a statically selectable
8- or 16-bit data bus. This architecture provides a fast and efficient processing device that
can satisfy the requirements of sophisticated applications based on high-level languages.
The MC68EC000 is object-code compatible with the MC68000, and code written for the
MC68EC000 can be migrated without modification to any member of the M68000 Family.
The MC68EC000 brings the performance level of the M68000 Family to cost levels
previously associated with 8-bit microprocessors. The MC68EC000 benefits from the rich
M68000 instruction set and its related high code density with low memory bandwidth
requirements.
