Overview
The AMD A80386DXL-40 is a high-speed, true static implementation of the Intel i386DX microprocessor. It operates at a clock frequency of 40 MHz with a 32-bit data width. The component utilizes a 132-pin CPGA package and supports an operating temperature range from 0°C to 100°C (TC). It features a 4 GB physical memory limit and 64 TB virtual memory capacity.
Feature Summary
- True static architecture for continuous operation without refresh cycles
- Compatible with standard i386DX software environments
- Integrated support for external math coprocessors
Applications
- Desktop computer systems requiring 32-bit processing
- Industrial control units needing wide temperature tolerance
- Legacy system maintenance and retro computing projects
Procurement Notes
Verify the specific stepping revision (A0, B0, B1, or D1) required for your motherboard compatibility before ordering. Confirm that the 132-pin CPGA footprint matches your existing socket. Ensure thermal management solutions are adequate for the 0°C to 100°C operating range specified in the datasheet.
Selection Notes
Select this model when a direct replacement for the Intel 386DX is needed with higher clock speeds. The DXL variant offers low-power characteristics suitable for systems where thermal dissipation is a constraint. Consider the 40 MHz speed as the maximum operational limit for stable performance.
Part Context
This processor belongs to the Am386 family, designed by Advanced Micro Devices to provide a pin-compatible alternative to Intel's 386 series. The DXL designation indicates a low-power version optimized for reduced energy consumption while maintaining full 32-bit architectural functionality and instruction set compatibility.
Replacement Considerations
Direct substitutes include other Am386DXL variants such as the A80386DXL-33, provided the lower clock speed meets system requirements. Verify that any replacement maintains the same 132-pin CPGA package and voltage specifications to ensure physical and electrical compatibility.
