TS68020VF1-20

Overview

The TS68020VF1-20 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 virtual memory. The device operates at a maximum clock frequency of 20 MHz with a 5.0 VDC power supply (±10%). It utilizes a 132-pin Ceramic Quad Flat Pack (CQFP) package and provides a 4-Gbyte direct addressing range via its 32-bit address bus.

Feature Summary

• Pipelined architecture with internal parallelism for concurrent instruction execution
• On-chip instruction cache to improve bus bandwidth and speed
• Co-processor interface supporting TS68881 and TS68882 floating-point units
• Dynamic bus sizing for efficient support of 8-, 16-, and 32-bit memories

Applications

• High-level language implementation requiring enhanced addressing modes
• Bit-oriented applications such as video graphics processing
• Systems utilizing virtual memory or virtual machine environments
• Applications requiring co-processing with 32-bit peripherals

Procurement Notes

Verify that the suffix 'V' corresponds to the specified commercial temperature range (-40°C to +85°C) rather than the military grade (-55°C to +125°C). Confirm the 'F' suffix indicates the CQFP package type. Ensure compliance with MIL-STD-883 Class B requirements if applicable to the specific lot. Check for RoHS status as the datasheet notes non-compliance for standard variants.

Selection Notes

Select this component when a full 32-bit data path and address bus are required alongside backward compatibility with earlier TS68000 object code. Consider the on-chip cache for performance-critical tasks. Verify that the 5V logic levels match the system design. Evaluate thermal resistance characteristics for the CQFP package in the intended enclosure environment.

Part Context

This part belongs to the TS68000 family of microprocessors, representing the first full 32-bit evolution from the 16-bit TS68000. It maintains software compatibility while introducing new instructions and addressing modes. The device integrates approximately 190,000 transistors and is designed for high-speed asynchronous bus operations.

Replacement Considerations
