MC68HC000RC8

Microprocessors Overview

The MC68HC000RC8 is a 32-bit microprocessor belonging to the M680x0 family, manufactured by Freescale Semiconductor. It operates at a clock speed of 8MHz and utilizes a 68-pin Plastic Grid Array (PGA) package with dimensions of 26.92mm x 26.92mm. The device features sixteen 32-bit data registers and sixteen 32-bit address registers, providing a 16-Mbyte direct addressing range. It supports memory-mapped I/O and six powerful instruction types operating on five main data types. As an HC variant, it incorporates low-power CMOS technology suitable for embedded applications requiring high performance with reduced power consumption.

Microprocessors Feature Summary

• Provides a 16-Mbyte direct physical address space
• Supports fourteen distinct addressing modes for flexible memory access

Microprocessors Applications

• Industrial control systems requiring deterministic processing
• Embedded instrumentation and measurement devices
• Communication equipment utilizing memory-mapped interfaces
• Consumer electronics based on the M680x0 instruction set

Microprocessors Procurement Notes

Verify the specific suffix RC8 confirms the 8MHz frequency rating and PGA package type against official Freescale documentation. Ensure compatibility with existing system clocks and voltage levels. Confirm RoHS compliance status if required for regulatory adherence. Cross-reference the manufacturer part number with current NXP or Freescale catalogs to verify availability and revision history before procurement.

Microprocessors Selection Notes

Select this component when a 32-bit architecture with a 16-Mbyte address space is required within a low-power constraint. The 8MHz speed suits applications not demanding higher throughput but needing robust instruction set compatibility. Consider the PGA package constraints for PCB layout and thermal management. Evaluate if the M680x0 instruction set aligns with existing software development tools and codebases.

Microprocessors Part Context

This processor is part of the M68000 family, which includes variants like the MC68000, MC68HC001, and MC68EC000. These processors share core architectural similarities but differ in bus widths and specific feature sets. The MC68HC000 series specifically emphasizes low-power operation compared to standard CMOS versions, making it distinct within the broader M680x0 lineage for battery-powered or thermally sensitive designs.

Microprocessors Replacement Considerations

Direct substitutes include other members of the M68000 family such as the MC68HC000 in different packages or speeds, provided pin compatibility is verified. The MC68EC000 offers similar functionality with potential differences in bus width configuration. Check official replacement guides from Freescale/NXP for pin-compatible alternatives that maintain the same instruction set and electrical characteristics.
