MC68EC040RC20A

Microprocessors Overview

The MC68EC040RC20A is a 32-bit microprocessor belonging to the M68000 family, manufactured by NXP USA Inc. It operates at a maximum clock frequency of 20 MHz and utilizes a PGA-68 ceramic package. The device features a 32-bit data bus width and an address bus width of 32 bits. It lacks an integrated floating-point unit and memory management unit, distinguishing it from other members of the M68040 series.

Microprocessors Feature Summary

• M68000-compatible high-performance 32-bit architecture
• Integrated instruction and data caches for improved execution speed
• Supports IEEE 1149.1 JTAG boundary scan testing

Microprocessors Applications

• Industrial control systems
• Communication gateways
• Embedded processing applications

Microprocessors Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm that the specific ordering suffix matches the required pinout and electrical specifications. Ensure compliance with relevant environmental regulations such as RoHS standards before integration into final products.

Microprocessors Selection Notes

Select this processor when a cost-effective solution without floating-point or MMU capabilities is required within the M68040 ecosystem. Consider the PGA-68 package constraints and verify system compatibility with its 20 MHz operational limit. Evaluate peripheral requirements against the available signal set defined in the technical documentation.

Microprocessors Part Context

This component is part of the broader M68040 family, which includes variants with floating-point units and memory management capabilities. The MC68EC040 specifically omits these advanced features to reduce complexity and cost while maintaining core 32-bit processing performance compatible with existing M68000 software environments.

Microprocessors Replacement Considerations

Direct substitutes include other members of the M68040 family such as the MC68LC040 or MC68040, provided the application can accommodate their additional functional blocks like FPU or MMU. Verify pin compatibility and thermal characteristics when considering alternative packages or speeds.
