Product Brief
MC68SEC000 Microprocessor
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 0.5µA 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

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.

Figure 2. Functional Signal Groups
Address Bus (A23-A0)
This 24-bit, unidirectional, three-state bus can address 16 Mbytes of data. It provides the address for bus
operation during all cycles except interrupt cycles. During interrupt cycles, A3, A2, and A1 reflect the level
of the interrupt being serviced, while A23-A4 and A0 are set to a logic high.
Data Bus (D15-D0)
This 16-bit, bidirectional, three-state bus is the general-purpose data path. Using the mode pin, you can
statically select either 8- or 16-bit modes for data transfer.
Asynchronous Bus Control
Asynchronous data transfers are handled using the following control signals: address strobe (AS), read/
write (R/W), upper and lower data strobes (UDS, LDS), and data transfer acknowledge (DTACK). The
address strobe signal indicates there is a valid address on the address bus. Read/write defines the data bus
transfer as a read or write cycle. The data strobes control the flow of data on the data bus and the data
transfer acknowledge indicates that the data transfer is complete.
Bus Arbitration Control
In multiple bus master systems, the bus arbitration circuit determines which device will be the bus master.
The bus request (BR) indicates that an external device requires bus mastership. A bus grant (BG) indicates
to all other potential bus master devices that the controller will release bus control at the end of the current
bus cycle.

Interrupt Control
The MC68SEC000 provides seven levels of interrupts. The interrupt priority level (IPL2, IPL1, IPL0) inputs
determine the priority level. Level 7 is nonmaskable and is the highest priority interrupt. Automatic vectoring,
based on IPL inputs, is available with the autovector (AVEC) input.
System Control
The system control inputs include the RESET, HALT, BERR, and MODE signals. These signals can reset
or halt the controller, indicate to the controller that a bus error has occurred, and select from 8- or 16-bit
operating mode.
Processor Status (FC2, FC1, FC0)
These active-high, three-state function code outputs indicate the mode (user or supervisor) and the address
space currently being accessed. The function code outputs are valid whenever AS is active.
