MC68SEC000FU20

Microprocessors Overview

The MC68SEC000FU20 is a static embedded microprocessor from the M68000 family, manufactured by NXP USA Inc. It features a 32-bit internal architecture with an 8- or 16-bit externally selectable data bus and a 24-bit address bus. The device supports clock frequencies of 10 MHz, 16 MHz, and 20 MHz. It operates on either 3.3V or 5.0V power supplies and includes sixteen 32-bit registers. The component is housed in a 64-lead plastic Quad Flat Pack (QFP) package measuring 14.0 mm x 14.0 mm with a 0.8 mm lead spacing. It functions within a commercial temperature range of 0°C to +70°C.

Microprocessors Feature Summary

• Static low-power HCMOS design allows for processor clock stopping to minimize energy consumption.
• Direct pin-for-pin hardware compatibility with the MC68EC000 in the plastic QFP package.
• Fully upward object-code compatible with all members of the M68000 Family.
• Supports seven interrupt levels with automatic vectoring capabilities.

Microprocessors Applications

• Personal digital assistants
• Portable measuring equipment
• Electronic games
• Battery-operated hand-held consumer products

Microprocessors Procurement Notes

Verify that the FU suffix corresponds to the 64-lead plastic QFP package and the 0°C to +70°C operating temperature range. Confirm the specific speed grade required (10, 16, or 20 MHz) as the base part number covers multiple frequency options. Ensure the system voltage matches the 3.3V or 5.0V operational requirements documented for this series.

Microprocessors Selection Notes

Select this component when a direct replacement for the MC68EC000 is needed with enhanced power management capabilities. It is suitable for applications requiring code migration from existing M68000 software without modification. Consider the 64-lead QFP package size constraints and the requirement for static low-power operation during idle periods.

Microprocessors Part Context

This microprocessor belongs to the M68000 family, which provides a robust foundation for sophisticated applications based on high-level languages. The MC68SEC000 serves as a cost-effective entry point to 32-bit processing, combining small footprint packages with static implementation technology for efficient embedded control.

Microprocessors Replacement Considerations

The MC68SEC000 is a direct replacement for the MC68EC000. Verify that the target application utilizes the plastic QFP package variant to ensure physical compatibility.
