INTRODUCTION
The MC68SEC000 is a cost-effective static embedded processor engineered for low-power applications. In
addition to providing the substantial cost and performance benefits of the MC68EC000, the low-power mode of
the MC68SEC000 provides significant advantages in power consumption and power management. The typical
current consumption of the MC68SEC000 is only 0.5
µ
A in static standby mode and 15.0mA in normal 3.3V
operation. The MC68SEC000 operates in either 3.3V or 5.0V systems. The remarkably low power consumption,
small footprint packages, and static implementation are combined in the MC68SEC000 for low-power
applications such as personal digital assistants, portable measuring equipment, electronic games, and battery-
operated hand-held consumer products.
The HCMOS MC68SEC000 static architecture is a direct replacement for the MC68EC000, which offers the
lowest cost entry point to 32-bit processing. The internal 32-bit architecture provides fast and efficient
processing that satisfies the requirements of sophisticated applications based on high-level languages. In
addition to being pin-for-pin compatible with the MC68EC000, the MC68SEC000 is object-code compatible with
any member of the M68000 Family. Complete code compatibility lets system designers reduce time to market
because they can rely on existing M68000 Family code and a broad base of established development tools.
The MC68SEC000 will be available in two small footprint packages: the 64 lead plastic Quad Flat Pack and the
64 lead Thin Quad Flat Pack. The Thin Quad Flat Pack provides a very small package footprint (10.0mm x
10.0mm), making it an ideal choice for portable applications.
The primary features of the MC68SEC000 embedded processor include the following:
Direct Replacement for the MC68EC000
Pin-for-pin compatibility with the MC68EC000 in the plastic QFP package
Vast selection of existing third-party development tools for the MC68EC000 support the
MC68SEC000
Software written for the MC68EC000 will run unchanged on the MC68SEC000

MOTOROLA MC68SEC000 PRODUCT INFORMATION 3
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
