TS68C000VR8A

Overview

The TS68C000VR8A 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 frequencies up to 12.5 MHz, supports a 16-Mbyte direct addressing range, and utilizes a 5VDC power supply. The device features a PGA-68 package, complies with MIL-STD-883 Class B standards, and functions within a military temperature range of -55°C to +125°C.

Feature Summary

• Implements the 16/32-bit microprocessor architecture with code compatibility to HMOS variants.
• Provides reduced power consumption compared to previous generation HMOS devices.
• Supports memory-mapped input/output and multiple interrupt priority levels.

Applications

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

Procurement Notes

Verify that the ordering suffix 'R' corresponds to the Pin Grid Array (PGA) package configuration as specified in the datasheet. Confirm that the voltage suffix 'V' aligns with the required commercial or extended temperature grade if applicable, though the base part specifies military range compliance. Ensure procurement channels provide documentation confirming adherence to DESC drawing 5962-89462 and MIL-STD-883 Class B quality conformance inspection requirements for mission-critical deployments.

Selection Notes

Select this component when a robust 16-bit microprocessor with a 24-bit address bus is required for environments demanding wide thermal tolerance. The device offers significant power reduction over HMOS equivalents while maintaining full instruction set compatibility. Consider the PGA-68 package form factor for board layout constraints and verify that the 5V logic interface matches the system's peripheral voltage levels without additional level shifting.

Part Context

This microprocessor belongs to the TS68000 family, which includes the TS68000, TS68008, and TS68020. It serves as a CMOS implementation designed to replace older HMOS versions with lower power dissipation. The device maintains architectural integrity with the broader 68000 family, ensuring that user-mode programs written for earlier iterations execute unchanged on this platform.

Replacement Considerations

Direct replacements include other variants within the TS68C000 series differentiated by clock speed (8 MHz, 10 MHz). Cross-vendor equivalents may exist but require verification of pinout and electrical characteristics against MIL-STD-883 Class B specifications.
