TS68C000VR12A

Overview

The TS68C000VR12A is a high-reliability microprocessor implementing the 16/32-bit architecture with a 16-bit data bus and 24-bit address bus. It operates at a maximum clock frequency of 12.5 MHz within a military temperature range of -55°C to +125°C. The device utilizes a 5VDC power supply and features 56 instruction types supporting five main data types. It includes 14 addressing modes, memory-mapped I/O, and is completely code-compatible with HMOS TS68000 and TS68020 implementations.

Feature Summary

• Implements 16/32-bit microprocessor architecture with 16-bit data bus and 24-bit address bus for 16-Mbyte direct addressing.
• Features low-power HCMOS technology dissipating significantly less power than HMOS equivalents.
• Provides complete code compatibility with TS68000, TS68008, and TS68020 processors.
• Complies with MIL-STD-883 Class B standards for high-reliability applications.

Applications

• Military and aerospace systems requiring high reliability
• Industrial control environments operating in extreme temperatures
• Embedded systems utilizing legacy 68000 family codebases

Procurement Notes

Verify that the specific suffix VR12A corresponds to the requested package type and speed grade, as the datasheet lists multiple package options including CQFP, DIL, LCCC, and PGA. Confirm compliance requirements against MIL-STD-883 Class B and DESC drawing 5962-89462. Ensure the supplier provides traceability documentation consistent with Atmel or Microchip Technology quality standards for hermetically sealed ceramic packages.

Selection Notes

Select this component when a robust, code-compatible replacement for HMOS 68000 processors is required in harsh environments. The device supports up to 12.5 MHz operation and functions across the full military temperature spectrum. Consider thermal resistance characteristics based on the chosen package variant to ensure junction temperatures remain within safe limits during continuous operation.

Part Context

The TS68C000 series represents a reduced-power CMOS implementation of the classic 68000 architecture. Manufactured by Atmel (now part of Microchip Technology), these devices are designed for high-reliability sectors. The VR12A designation indicates a specific configuration within the 12.5 MHz speed bin, adhering to strict military screening protocols.

Replacement Considerations

Direct pin-to-pin replacements include other variants within the TS68C000 family such as the 8 MHz or 10 MHz versions, provided timing constraints allow. Legacy HMOS TS68000 devices are functionally compatible but consume more power. Verify that any substitute maintains the same ceramic package style and military qualification level.
