A80386DXL-33

Overview

The A80386DXL-33 is a 32-bit microprocessor manufactured by Advanced Micro Devices, based on the Am386DXL core architecture. It operates at a clock speed of 33 MHz with a 1x multiplier and supports a maximum frequency of 66.67 MHz. The device features a 32-bit external data bus and a 30-bit address bus width. It is housed in a 132-pin Plastic Quad Flat Package (PQFP) or CPGA package, measuring approximately 37.59 x 37.59 mm. The processor utilizes CMOS technology and includes low-power mode capabilities.

Feature Summary

• Supports 32-bit processing architecture for enhanced computational throughput
• Integrates low-power operational modes to manage energy consumption
• Utilizes CMOS fabrication technology for stable performance

Applications

• Desktop computer systems requiring 386-class processing
• Industrial control applications utilizing embedded processors
• Legacy hardware restoration and retro computing projects

Procurement Notes

Verify the specific package variant (PQFP vs. CPGA) against project requirements, as datasheets may list multiple physical forms. Confirm the stepping revision (A0, B0, B1, or D1) if compatibility with existing system boards is critical. Ensure the component meets the required operating temperature range of -40°C to +100°C for industrial environments. Cross-reference the ECCN code 3A001.A.3 for export compliance regulations before procurement.

Selection Notes

Select this component when a 33 MHz 32-bit processor is required for legacy system maintenance. Compare the 132-pin footprint against available motherboard sockets to ensure mechanical fit. Evaluate power dissipation characteristics relative to the cooling solution provided in the target enclosure. Consider the availability of compatible chipsets that support the Am386DXL memory controller interface.

Part Context

This part belongs to the AMD Am386 family, serving as a successor to the Intel 80386 line. It was designed to provide competitive performance in the mid-1990s PC market. The DXL designation typically indicates enhanced features or manufacturing process improvements over standard DX variants within the same generation of microprocessors.

Replacement Considerations

Compatible substitutes include the NG80386DXL-33S and other Am386DXL variants with matching pinouts. Verify electrical compatibility with the host system's chipset before substitution.
