TS68C000VC12A

Overview

The TS68C000VC12A is a high-reliability, reduced-power microprocessor implementing the 16/32-bit architecture. It features a 16-bit data bus and a 24-bit address bus, providing a 16-Mbyte direct addressing range. The device operates at a maximum clock frequency of 12.5 MHz with a supply voltage of 5VDC ± 10%. It supports 56 instruction types across five main data types using 14 addressing modes. Manufactured in compliance with MIL-STD-883 Class B standards, it ensures robust performance in demanding environments.

Feature Summary

• Implements the 16/32-bit microprocessor architecture with code compatibility to HMOS TS68000 and TS68020 variants.
• Features HCMOS technology for significantly reduced power consumption compared to previous HMOS implementations.
• Includes 16-/32-bit data and address registers supporting memory-mapped input/output operations.
• Complies with MIL-STD-883 Class B quality conformance inspection requirements.

Applications

• Military and aerospace systems requiring high reliability
• Industrial control applications operating in extreme temperatures
• Embedded systems utilizing the 68000 family instruction set

Procurement Notes

Verify that the specific suffix 'VC12A' corresponds to the requested package type and speed grade within the manufacturer's official ordering information. Confirm that the component meets the required MIL-STD-883 Class B screening levels for the intended application environment. Ensure all electrical parameters align with the system design specifications before procurement.

Selection Notes

Select this component when a high-reliability microprocessor with 16-bit data width and 24-bit address capability is required. It is suitable for designs needing operation up to 12.5 MHz with a standard 5V supply. Consider the available ceramic packages such as DIL 64 or CQFP 68 based on board layout constraints and thermal management needs.

Part Context

The TS68C000 series represents a CMOS implementation of the classic 68000 architecture, offering lower power dissipation than its HMOS predecessors. This specific variant is part of a family including 8 MHz, 10 MHz, and 12.5 MHz versions, designed for high-reliability applications where radiation hardness and temperature stability are critical factors.

Replacement Considerations

Direct replacements include other TS68C000 variants with different speed grades (e.g., TS68C000-8 or TS68C000-10) if timing requirements allow. Cross-family migration to the TS68020 may be considered for 32-bit data bus requirements, though pinouts and power characteristics will differ.
