MC68SEC000FU16

Microprocessors Overview

The MC68SEC000FU16 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 statically selectable data bus and a 24-bit address bus. The component supports clock speeds 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 (eight address and eight data) along with seven interrupt levels. The device is housed in a 64-pin plastic Quad Flat Pack (QFP) package measuring 14.0 mm x 14.0 mm with a lead spacing of 0.8 mm. It functions within a commercial temperature range of 0°C to +70°C.

Microprocessors Feature Summary

• Direct hardware and object-code replacement for the MC68EC000 with pin-for-pin compatibility.
• Static low-power HCMOS design allowing processor clock stoppage while maintaining internal state.
• Full upward object-code compatibility with all members of the M68000 Family.
• Supports both 3.3V and 5.0V system operations.

Microprocessors Applications

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

Microprocessors Procurement Notes

Verify that the specific suffix FU corresponds to the 64-lead plastic QFP package variant. Confirm the operating temperature range matches the required commercial specification of 0°C to +70°C. Ensure the selected speed grade aligns with the system timing requirements for 10, 16, or 20 MHz operation. Cross-reference the manufacturer documentation to validate current production status and availability constraints.

Microprocessors Selection Notes

Select this component when a direct upgrade path from the MC68EC000 is required without altering board layout or software code. Choose the 64-lead QFP package if larger footprint dimensions are acceptable compared to the TQFP option. Verify that the target application environment remains within the specified commercial temperature limits. Ensure the design utilizes existing M68000 development tools compatible with the EC000 series.

Microprocessors Part Context

This microprocessor belongs to the M68000 family, providing a cost-effective entry point into 32-bit processing. It is engineered specifically for low-power applications where static standby current consumption is critical. The device maintains complete software compatibility with established M68000 ecosystem tools and codebases, facilitating rapid deployment in portable electronic systems.

Microprocessors Replacement Considerations

The MC68SEC000 serves as a direct replacement for the MC68EC000. It offers identical pinout and object-code compatibility, allowing for seamless migration without hardware redesign or software modification. Existing third-party developer tools designed for the MC68EC000 directly support this component.
