TS68C000VC8A

Overview

The TS68C000VC8A is a high-reliability, reduced-power microprocessor implementing the TS68000 architecture. It features a 16-bit data bus and a 24-bit address bus, providing a 16-Mbyte direct addressing range. The device operates on a 5VDC power supply with a tolerance of ±10%. It supports three clock frequency versions: 8 MHz, 10 MHz, and 12.5 MHz. The component is designed for military temperature ranges from -55°C to +125°C and complies with MIL-STD-883 Class B standards.

Feature Summary

• Implements the TS68000 16/32-bit microprocessor architecture with complete code compatibility to HMOS TS68000 and TS68020 implementations.
• Features HCMOS technology that reduces power consumption by an order of magnitude compared to previous HMOS generations.
• Includes 56 powerful instruction types supporting operations on five main data types and memory-mapped input/output.
• Provides 14 addressing modes and utilizes a 16-bit ALU within both the Address and Data Execution Units.

Applications

• Military and aerospace systems requiring compliance with MIL-STD-883 Class B standards.
• High-reliability embedded control applications utilizing the 68000 family instruction set.
• Systems interfacing with synchronous EF 6800 peripheral devices via standard enable signals.

Procurement Notes

Verify the specific suffix 'VC8A' against manufacturer documentation to confirm package type and screening level. Ensure procurement channels provide traceability to DESC drawing 5962-89462. Confirm that the delivered units meet the required MIL-STD-883 Class B inspection criteria for the intended operating environment.

Selection Notes

Select this component when a robust 16-bit microprocessor is required for harsh environments. It is suitable for designs needing code compatibility with existing 68000 software while demanding lower power dissipation than HMOS alternatives. Consider thermal management requirements based on the specific ceramic package selected, as junction-to-ambient resistance varies by form factor.

Part Context

The TS68C000 series represents a CMOS implementation of the classic 68000 architecture, manufactured under high-reliability specifications. Originally associated with Atmel and Thomson-CSF, these components are maintained for legacy and defense applications. The VC8A designation typically indicates a specific ceramic quad flat pack configuration optimized for surface mount assembly in ruggedized electronics.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided source material. Direct replacement requires verifying pinout compatibility and ensuring the alternative component meets the same MIL-STD-883 Class B qualification standards.
