MC68SEC000FU20R2

Microprocessors Overview

The MC68SEC000FU20R2 is a microprocessor unit (MPU) belonging to the M680x0 family, manufactured by NXP USA Inc. It features an EC000 core with a single 32-bit architecture and operates at a clock speed of 20 MHz. The device is housed in a 64-pin Quad Flat Package (QFP) with surface mount installation. It supports I/O voltages of 3.3V and 5.0V and functions within an ambient temperature range of 0°C to 70°C. The component is supplied in tape and reel packaging.

Microprocessors Feature Summary

• Direct pin-for-pin replacement for the MC68EC000 in plastic QFP packages
• Low-power HCMOS technology with static design allowing processor clock stop
• Supports both 3.3V and 5.0V operation modes
• Compatible with existing third-party development tools for the MC68EC000

Microprocessors Applications

• Embedded systems requiring direct upgrade from MC68EC000
• Industrial control applications utilizing M680x0 architecture
• Communication controllers designed for passive ISDN or similar protocol engines

Microprocessors Procurement Notes

Verify the specific suffix 'FU20R2' against official NXP documentation to confirm package type, speed grade, and environmental rating. Confirm RoHS compliance status and REACH registration details prior to procurement. Check current product lifecycle status as older M680x0 components may be discontinued or subject to long-lead times.

Microprocessors Selection Notes

Select this component when a drop-in replacement for the MC68EC000 is required without PCB layout changes. Ensure the system design supports the specified 3.3V or 5.0V I/O levels. Verify that the operating temperature range meets the application's environmental requirements. Confirm compatibility with existing software written for the MC68EC000 core.

Microprocessors Part Context

This part is part of the M680x0 series of 32-bit microprocessors originally developed by Motorola and now managed by NXP. The M680x0 family is known for its RISC-like instruction set and widespread use in embedded applications. The SEC variant specifically addresses power management and low-power requirements while maintaining binary compatibility with earlier EC models.

Microprocessors Replacement Considerations

The MC68SEC000 is officially documented as a direct replacement for the MC68EC000. Ensure that any substitute parts maintain pin-for-pin compatibility in the 64-QFP package. Verify that the replacement supports the same 3.3V/5.0V I/O voltage options.
