MC68EC040RC25A

Microprocessors Overview

The MC68EC040RC25A is a member of the M68040 family, a high-performance 32-bit microprocessor. It features a 32-bit integer unit and a 32-bit external data bus. The device operates at a clock frequency of 25 MHz. Unlike the standard MC68040, this derivative excludes the integrated floating-point unit (FPU) and memory management unit (MMU). It supports instruction and data caches for performance optimization.

Microprocessors Feature Summary

• M68000-compatible 32-bit architecture with an advanced integer pipeline
• Integrated instruction and data cache subsystems
• Support for IEEE 1149.1 JTAG boundary scan testing
• Bus arbitration and snooping capabilities for multi-processor systems

Microprocessors Applications

• High-performance embedded control systems
• Industrial automation controllers
• Communication infrastructure equipment
• Network routers and switches

Microprocessors Procurement Notes

Verify component authenticity through authorized NXP distributors or certified secondary market suppliers. Request original manufacturer documentation to confirm revision levels. Inspect packages for physical damage. Ensure compliance with RoHS directives if required by the application environment. Confirm end-of-life status implications for long-term supply continuity.

Microprocessors Selection Notes

Select this component when M68000 software compatibility is mandatory but FPU/MMU hardware overhead is unnecessary. Evaluate system requirements against the 25 MHz operating speed. Consider the absence of on-chip MMU for memory protection strategies. Verify that the package type matches the PCB layout constraints.

Microprocessors Part Context

This part belongs to the Motorola/Freescale/NXP M68040 family, representing third-generation 32-bit microprocessors. The 'EC' designation indicates the elimination of specific high-cost blocks like the FPU and MMU compared to the base MC68040 model. The suffix 'R' typically denotes tape-and-reel packaging, while '25A' specifies the speed grade.
