N82C08-8

Overview

The N82C08-8 is a Dynamic RAM (DRAM) memory controller integrated circuit manufactured by Altera. It is designed to manage DRAM operations and supports the IAPX286 bus architecture. The device operates with a maximum clock frequency of 16 MHz and features five programmable refresh modes for memory management. It is housed in a 68-pin PLCC package and is intended for surface mount applications.

Feature Summary

• Supports IAPX286 bus interface
• Features five programmable refresh modes
• Operates up to 16 MHz clock frequency

Applications

• Dynamic RAM memory control systems
• IAPX286-based computer architectures
• Embedded memory management units

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm package integrity and pin alignment prior to installation. Ensure compatibility with existing system bus protocols and voltage levels. Review datasheet specifications for operating temperature ranges and electrical limits to prevent operational failure.

Selection Notes

Select this controller for designs requiring IAPX286 bus compatibility and specific DRAM refresh configurations. Evaluate the 16 MHz speed limit against system timing requirements. Consider the 68-PLCC package constraints for PCB layout and thermal management during the design phase.

Part Context

This component belongs to the Altera peripheral IC family, specifically within the memory controller category. Altera was acquired by Intel, and these legacy components are often referenced in older industrial or embedded computing systems that utilize the IAPX286 standard.
