TS68C000VR10A

Overview

The TS68C000VR10A is a high-reliability, reduced-power HCMOS implementation of the 16/32-bit microprocessor 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 10 MHz with a supply voltage of 5VDC ± 10%. It includes 56 instruction types, 14 addressing modes, and memory-mapped I/O. The unit supports military temperature ranges from -55°C to +125°C and is packaged in a CQFP-68 ceramic quad flat pack.

Feature Summary

• Provides code compatibility with HMOS TS68000, TS68008, and TS68020 processors while significantly reducing power consumption.
• Features a 16-bit bidirectional data bus and a 24-bit unidirectional address bus for system interfacing.
• Supports asynchronous bus control, bus arbitration, and encoded interrupt priority levels.
• Manufactured in hermetically sealed ceramic packages compliant with MIL-STD-883 Class B standards.

Applications

• Military and aerospace embedded systems requiring radiation-hardened or high-reliability processing
• Industrial control applications operating in extreme temperature environments
• Legacy system upgrades requiring architectural compatibility with existing 68000 family software

Procurement Notes

Verify that the specific suffix VR10A corresponds to the requested 10 MHz speed grade and CQFP-68 package configuration. Confirm compliance requirements against MIL-STD-883 Class B and DESC drawing 5962-89462. Ensure handling procedures account for humidity sensitivity and electrostatic discharge protection during installation.

Selection Notes

Select this component when a CMOS-based replacement for legacy HMOS designs is required without modifying existing software. Consider the thermal resistance characteristics of the CQFP-68 package for heat dissipation planning. Verify that the 10 MHz operational speed meets the timing constraints of the target memory and peripheral interfaces.

Part Context

This microprocessor belongs to the TS68C000 series, which offers multiple speed grades including 8 MHz, 10 MHz, and 12.5 MHz variants. The series maintains full architectural compatibility with the original 68000 family while utilizing modern HCMOS technology for lower power dissipation. The VR10A designation specifically identifies the 10 MHz performance tier within this product line.

Replacement Considerations

Direct functional replacements include the TS68C000-8 (8 MHz) and TS68C000-12 (12.5 MHz) variants, provided timing margins allow for speed adjustments. Legacy HMOS TS68000 devices are architecturally compatible but differ in power consumption and manufacturing process.
