P82C08-16

Overview

The Altera P82C08-16 is a Dynamic RAM (DRAM) memory controller IC designed for legacy microprocessor systems. It supports up to 1 MB of DRAM storage using 64k and 256k DRAM integrated circuits. The component is compatible with the iAPX 286, iAPX 186/188, and iAPX 86/88 processor families. It is housed in a 48-pin Dual In-line Package (DIP).

Feature Summary

• Supports up to 1 MB of DRAM capacity using 64k and 256k DRAM ICs.
• Compatible with iAPX 286, iAPX 186/188, and iAPX 86/88 processors.

Applications

• Memory management for iAPX 286 based systems.
• Memory expansion for iAPX 186/188 architectures.
• Storage control for iAPX 86/88 platforms.

Procurement Notes

Verify the manufacturer designation carefully, as this component was originally an Intel product later associated with Altera. Confirm the package type is 48-DIP and the speed grade is -16. Ensure compatibility with legacy iAPX processor families before procurement.

Selection Notes

Select this controller for retro computing or legacy system maintenance involving iAPX processors. It is suitable for designs requiring 1 MB DRAM support via 64k or 256k chips. Verify pinout and voltage requirements against the specific iAPX variant in use.

Part Context

This component belongs to the family of dynamic RAM controllers used in early x86-based computer architectures. Originally developed by Intel, it was later distributed under the Altera brand following corporate acquisitions. It serves as a critical interface between legacy processors and DRAM modules.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to its legacy status and specific compatibility with iAPX processors, direct functional equivalents may be limited to other vintage DRAM controllers with matching pinouts and timing specifications.
