MC68EC000FU12

Microprocessors Overview

The MC68EC000FU12 is a 32-bit microprocessor featuring a 12 MHz maximum clock frequency. It utilizes a 23-bit address bus and a 16-bit external data bus, operating in fixed-point format without integrated cache. The component is housed in a plastic QFP-68 package with 68 terminals. It supports seven external interrupt devices and lacks boundary scan capabilities. Designed for static operation, it facilitates power savings when the processor clock is stopped.

Microprocessors Feature Summary

• Static core design allowing processor clock stoppage for significant power reduction
• Full compatibility with MC68000 and MC68EC000 instruction sets
• Integrated System Integration Module (SIM) reducing external logic requirements
• Programmable peripheral chip selects with wait state generation

Microprocessors Applications

• Portable consumer electronics requiring low power consumption
• Embedded systems needing cost-effective performance
• Applications utilizing SRAM, EPROM, or FLASH memory interfaces

Microprocessors Procurement Notes

Verify the specific suffix 'FU12' against official Motorola documentation to confirm package type and speed grade. Ensure the source document explicitly lists this part number variant. Confirm RoHS compliance status as older Motorola parts may not meet current standards. Validate pinout compatibility if replacing existing designs.

Microprocessors Selection Notes

Select this component for applications requiring M68000 architecture compatibility with reduced pin count compared to full 68000 variants. Consider the static design benefits for battery-operated devices. Evaluate the integrated SIM features to minimize external glue logic. Verify that the 12 MHz speed meets system timing requirements.

Microprocessors Part Context

This processor belongs to the Motorola DragonBall family of integrated portable system processors. It combines a 68EC000 core with on-chip peripherals to reduce board space and system cost. The family targets the portable consumer market by offering high integration and low power consumption within an efficient package.

Microprocessors Replacement Considerations

The MC68EC000FU12 is functionally identical to the MC68EC000 core. Check for compatible packages such as PQFP68. Verify electrical characteristics match the original design requirements before substitution.
