MC68HC001EI8

Microprocessors Overview

The MC68HC001EI8 is a low-power microprocessor belonging to the M68000 family, manufactured by Freescale Semiconductor. It features a statically selectable 8-bit or 16-bit data bus width and operates within a 16-Mbyte direct addressing range. The device integrates sixteen 32-bit data registers and sixteen 32-bit address registers, supporting memory-mapped I/O and fourteen distinct addressing modes. Designed for applications requiring reduced power consumption, it utilizes HCMOS technology and supports six powerful instruction types with operations on five main data types.

Microprocessors Feature Summary

• Statically selectable 8-bit or 16-bit data bus configuration
• Low-power HCMOS architecture optimized for energy efficiency
• Supports sixteen 32-bit data and address registers
• Enables memory-mapped input/output operations

Microprocessors Applications

• Embedded systems requiring low power consumption
• Applications utilizing memory-mapped I/O architectures
• Systems needing statically configurable data bus widths

Microprocessors Procurement Notes

Verify the specific suffix 'EI8' against official NXP/Freescale documentation to confirm package type and temperature rating. Ensure compatibility with existing system buses regarding the static 8/16-bit selection. Confirm availability status as legacy components may have limited supply chains.

Microprocessors Selection Notes

Select this component when a statically fixed data bus width is preferred over dynamic switching. Evaluate the requirement for a 16-Mbyte addressing space and the necessity of thirty-two-bit register architecture. Consider the low-power benefits of the HC variant compared to standard CMOS counterparts in battery-operated designs.

Microprocessors Part Context

This part belongs to the M68000 microprocessor family, specifically the HC (High-performance CMOS) subset. It shares architectural similarities with the MC68HC000 and MC68EC000 but distinguishes itself through its low-power characteristics and the ability to statically select between 8-bit and 16-bit data paths for interface flexibility.

Microprocessors Replacement Considerations

The MC68HC000 serves as a primary alternative within the same family, offering similar capabilities without the low-power optimization. The MC68EC000 provides comparable functionality with potential differences in pinout or power specifications. Verify electrical compatibility before substitution.
