MC68SEC000PB20

Microprocessors Overview

The MC68SEC000PB20 is a 32-bit microprocessor from the Motorola M68000 family, manufactured by Motorola (NXP). It operates at a maximum clock frequency of 20 MHz and utilizes a plastic quad flat package with 68 pins. The device features a 16-mbyte direct addressing range and sixteen 32-bit data and address registers. It supports static design allowing for processor clock stopping and offers low-power HCMOS technology. The component is compatible with 3.3V or 5V operation and provides pin-for-pin compatibility with the MC68EC000 in plastic QFP packages.

Microprocessors Feature Summary

• Direct replacement for the MC68EC000 with pin-for-pin compatibility
• Low-power HCMOS technology enabling static clock stopping
• Supports both 3.3V and 5V operation modes
• Compatible with existing third-party development tools for the MC68EC000

Microprocessors Applications

• Embedded systems requiring low power consumption
• Applications utilizing existing MC68EC000 software codebases
• Designs needing 3.3V or 5V voltage operation flexibility

Microprocessors Procurement Notes

Verify the specific package type and voltage requirements against your system design before procurement. Confirm that the supplier provides genuine Motorola or NXP components. Ensure compatibility with your existing development tools intended for the MC68EC000 family. Check for any specific ordering suffixes that might affect performance or packaging details.

Microprocessors Selection Notes

Select this component when a direct upgrade to the MC68EC000 is required without hardware redesign. It is suitable for applications where low power consumption is critical, specifically those benefiting from static clock stopping capabilities. Consider its compatibility with 3.3V and 5V systems for flexible power supply integration. Ensure your development environment supports the M68000 instruction set architecture.

Microprocessors Part Context

The MC68SEC000PB20 belongs to the M68000 microprocessor family, which includes variants like the MC68HC000 and MC68EC000. These processors share common features such as a 16-mbyte addressing range and memory-mapped I/O. The SEC variant specifically emphasizes low-power characteristics while maintaining software compatibility with previous generations, facilitating easier migration for embedded designers.

Microprocessors Replacement Considerations

The MC68SEC000PB20 serves as a direct replacement for the MC68EC000 in plastic QFP and TQFP packages. Software written for the MC68EC000 runs unchanged on this component. Verify package compatibility if substituting into designs originally using other M68000 variants.
