TS68020VR16

Overview

The TS68020VR16 is a high-performance 32-bit microprocessor from the TS68000 family, manufactured using HCMOS technology. It features a pipelined architecture with an on-chip instruction cache and supports dynamic bus sizing for 8-, 16-, and 32-bit peripherals. The device operates at a maximum clock frequency of 16.67 MHz and requires a 5.0 VDC power supply. It includes sixteen 32-bit general-purpose registers, two supervisor stack pointers, and full support for virtual memory and co-processors like the TS68881.

Feature Summary

• Pipelined architecture with on-chip instruction cache to improve bus bandwidth
• Dynamic bus sizing supporting 8-, 16-, and 32-bit memories
• Full support for virtual memory and virtual machine environments
• Co-processor interface compatible with TS68881 and TS68882

Applications

• High-level language implementation requiring addressing mode extensions
• Bit-oriented applications such as video graphics processing
• Systems utilizing companion floating-point co-processors
• Virtual memory and virtual machine architectures

Procurement Notes

Verify that the 'V' suffix corresponds to the specified commercial temperature range (-40°C to +85°C) rather than the military grade ('M' suffix). Confirm package type matches requirements, as this model typically utilizes the CQFP 132 ceramic quad flat pack. Ensure compliance with MIL-STD-883 Class B screening if required by the specific application environment.

Selection Notes

Select this component when a full 32-bit data path and address bus are necessary for complex computing tasks. It is suitable for designs requiring compatibility with earlier TS68000 object code while needing enhanced performance through caching. Consider thermal management strategies, as power dissipation increases with clock speed and load conditions.

Part Context

This processor represents the evolution of the 16-bit TS68000 into a complete 32-bit implementation. It maintains software compatibility with the family while introducing new instructions and addressing modes. The device integrates approximately 190,000 transistors within a hermetically sealed ceramic package, designed for high reliability in demanding electronic systems.

Replacement Considerations

Compatible variants include the TS68020MF16 (Military grade, same speed) and TS68020MR20 (Military grade, higher speed). Verify pinout and voltage specifications before substitution.
