A80C188XL25

Overview

The A80C188XL25 is a 16-bit RISC microprocessor based on the i186 architecture, manufactured by Intel and later associated with Altera. It operates at a clock speed of 25 MHz using CMOS technology. The device is housed in a 68-pin Ceramic Pin Grid Array (CPGA) package. It requires a nominal 5 V power supply and functions within a commercial temperature range of -40 °C to 70 °C. The component features 68 terminals with tin/lead surface finish.

Feature Summary

• Implements 16-bit RISC instruction set architecture derived from the i186 core.

Applications

• Embedded control systems requiring 16-bit processing.

Procurement Notes

Verify component authenticity through authorized distributors or certified secondary market suppliers. Confirm the specific suffix '25' corresponds to the 25 MHz speed grade. Check for RoHS compliance status as original versions may not meet current environmental standards. Ensure the CPGA68 package condition matches system requirements.

Selection Notes

Select this component only if legacy i186 compatibility and 25 MHz performance are required. Evaluate the availability of 68-pin CPGA footprints in the target design. Consider that the device is obsolete; verify long-term supply chain stability before finalizing the design.

Part Context

This processor belongs to the Intel 80C186 family, which was subsequently integrated into Altera's portfolio following industry acquisitions. It serves as a bridge between older 8-bit architectures and modern 32-bit processors, offering a cost-effective solution for embedded applications needing 16-bit data paths.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As an obsolete component, direct pin-compatible replacements are not listed. Designers should consult official obsolescence notices for recommended migration paths.
