TS68020MR25

Overview

The TS68020MR25 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 housed in a 132-pin Ceramic Quad Flat Pack (CQFP) package.

Feature Summary

• Pipelined architecture with internal parallelism and on-chip instruction cache
• Full 32-bit data paths and address buses with dynamic bus sizing
• Co-processor interface supporting TS68881 and TS68882 floating point units
• Comprehensive virtual memory and virtual machine support

Applications

• High-level language implementation requiring enhanced addressing modes
• Bit-oriented applications such as video graphics processing
• Systems utilizing companion 32-bit peripherals via co-processor interface
• Virtual memory environments requiring multiple vector tables

Procurement Notes

Verify the specific suffix 'M' corresponds to the required military screening standard, such as MIL-STD-883 Class B or DESC 5962. Confirm that the 'R' suffix aligns with the specified 132-pin CQFP ceramic package configuration. Ensure compatibility with the 5.0 VDC ± 10% power supply requirements and -55°C to +125°C operating temperature range before integration.

Selection Notes

Select this component when a full 32-bit implementation of the TS68000 family is required with speeds up to 25 MHz. It is suitable for designs needing object code compatibility with earlier processors while utilizing new bit field data types. Consider the CQFP package constraints and thermal resistance characteristics for proper heat dissipation in the target application environment.

Part Context

This microprocessor represents the evolution of the TS68000 family from 16-bit to full 32-bit architecture. It combines CMOS structures for speed and low power with HMOS structures for silicon area efficiency. The device integrates approximately 190,000 transistors and utilizes a two-level microcode store consisting of microrom and nanorom for execution control.

Replacement Considerations

Compatible variants include the TS68020MF16 and TS68020MF20, which share the same core architecture but differ in maximum clock frequency specifications. Verify pinout compatibility between the PGA and CQFP packages if substituting different package suffixes.
