TS68020MF25

Overview

The TS68020MF25 is a high-performance 32-bit microprocessor from the TS68000 family, manufactured using HCMOS technology. It features a 16.67 MHz to 25 MHz clock speed and operates on a 5.0 VDC ± 10% power supply. The device includes a 4-Gbyte direct addressing range, sixteen 32-bit general-purpose registers, and an on-chip instruction cache. It is housed in a hermetically sealed 132-pin Ceramic Quad Flat Pack (CQFP) package.

Feature Summary

• Object code compatible with earlier TS68000 microprocessors while providing enhanced support for high-level languages through new addressing modes.
• Features a fast on-chip instruction cache that accelerates instructions and improves bus bandwidth.
• Includes a co-processor interface designed for companion 32-bit peripherals such as floating-point units.
• Supports virtual memory and virtual machines with full dynamic bus sizing for 8-, 16-, and 32-bit memories.

Applications

• Video graphics applications utilizing bit field data types
• Systems requiring co-processor interfaces for floating-point operations
• Virtual machine environments

Procurement Notes

Verify compliance with MIL-STD-883 Class B or DESC 5962 standards during acquisition. Confirm the specific suffix indicates the CQFP 132 ceramic package. Ensure the operating temperature range matches the military grade requirements of -55°C to +125°C. Check for RoHS non-compliance status as indicated by manufacturer specifications.

Selection Notes

Select this component when a full 32-bit implementation of the 68000 architecture is required with integrated caching. Consider the 132-pin CQFP package for space-constrained designs needing hermetic sealing. Evaluate thermal resistance characteristics for heat dissipation planning within the specified case temperature limits.

Part Context

This microprocessor represents the first full 32-bit evolution of the TS68000 family, combining 32-bit internal structures with 32-bit address and data buses. It utilizes a pipelined architecture allowing concurrent instruction execution. The device integrates approximately 190,000 transistors to deliver high performance while maintaining low power consumption relative to its processing capabilities.

Replacement Considerations

Compatible variants include the TS68020MF20 and TS68020MF16, which share the same CQFP 132 package but operate at lower maximum clock frequencies of 20 MHz and 16.67 MHz respectively. Substitution requires verification of timing constraints against the system clock requirements.
