OVERVIEW
Figure 1 is a block diagram of the MC68SEC000 embedded processor. This processor provides a 24-bit
address bus and a statically selectable 8- or 16-bit data bus, sixteen 32-bit registers, and seven interrupt
levels.

HARDWARE/SOFTWARE COMPATIBILITY
The MC68SEC000 embedded processor is hardware compatible with the MC68EC000, object-code
compatible with the MC68EC000, and upward compatible with all members of the M68000 Family. Object-
code compatibility with the M68000 enables code written for the MC68SEC000 to be migrated without
modification to any member of the M68000 Family.
LOW-POWER MODE
The MC68SEC000 provides static low-power operation. While in low-power mode, power consumption is
reduced to its quiescent value while maintaining the internal state of the processor. The recommended
method for placing the MC68SEC000 into low-power mode is described in
Addendum to M68000 8-/16-/32-
Bit Microprocessor Users Manual, M68000 UMAD/AD.
