TS68020VF25

Overview

The TS68020VF25 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 processor speeds up to 25 MHz. The device includes sixteen 32-bit general-purpose registers, a 4-Gbyte direct addressing range, and full support for virtual memory. It operates on a 5.0 VDC power supply and is available in a 132-pin Ceramic Quad Flat Pack (CQFP) package.

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

• Video graphics applications utilizing bit field data types
• Systems requiring virtual memory and virtual machine support
• High-level language implementations with extended addressing modes
• Applications necessitating co-processor integration for floating-point operations

Procurement Notes

Verify that the 'V' suffix confirms the -40°C to +85°C operating temperature range. Confirm the 'F' suffix indicates the 132-pin CQFP ceramic package. Ensure compliance with MIL-STD-883 Class B or DESC 5962 standards if required by the specific application environment.

Selection Notes

Select this component when a full 32-bit implementation of the 68000 family is required with speeds up to 25 MHz. Consider the integrated cache for performance gains and the co-processor interface for specialized arithmetic needs. Verify package availability and thermal management requirements for the CQFP form factor.

Part Context

The TS68020 represents the first full 32-bit evolution of the TS68000 family, maintaining object code compatibility while introducing 32-bit data paths and addressing. It utilizes approximately 190,000 transistors in a low-power HCMOS process. The device integrates a bus controller and micromachine section to manage asynchronous bus cycles and instruction decoding efficiently.

Replacement Considerations

TS68020MF25: Identical functional specifications but rated for military temperature range (-55°C to +125°C). TS68020MF20: Lower clock speed variant (20 MHz) with military temperature rating.
