A82078

Overview

The A82078 is a Dynamic RAM (DRAM) memory controller integrated circuit manufactured by Altera. It is designed to manage data flow between system processors and DRAM modules. The device supports a configuration of 2M x 8 bits, providing specific addressing and control capabilities for memory subsystems. It is housed in a 68-contact Ceramic Pin Grid Array (CPGA) package, which facilitates thermal dissipation and reliable connection to printed circuit boards in high-performance computing environments.

Feature Summary

• Provides dedicated hardware logic for controlling dynamic random-access memory operations
• Supports 2 megabit by 8-bit memory organization architecture
• Utilizes a 68-pin ceramic pin grid array package for robust mechanical stability

Applications

• High-performance computer systems requiring dedicated DRAM management
• Embedded applications utilizing Altera programmable logic solutions
• Industrial control systems with specific memory interface requirements

Procurement Notes

Verify the exact package variant and revision level against official Intel/Altera documentation before procurement. Confirm that the 68-CPGA footprint matches the target design constraints. Ensure compliance with RoHS directives as indicated in current manufacturer listings. Cross-reference part numbers with mature device lists to confirm availability status and lifecycle stage.

Selection Notes

Select this component when a dedicated DRAM controller is required for a 2Mx8 memory configuration within an Altera-based system. Evaluate the CPGA package suitability for the intended thermal and mechanical environment. Consider compatibility with existing Altera FPGA or SoC architectures to ensure seamless integration into the memory subsystem design without additional external controller logic.

Part Context

This component belongs to the Altera family of peripheral controllers, often used in conjunction with Altera's programmable logic devices such as FPGAs and CPLDs. As a mature device from the original Altera Corporation, now part of Intel, it serves specialized roles in legacy or specific industrial designs where dedicated memory control hardware is preferred over soft-core implementations.

Replacement Considerations

Consult Intel's official mature device documentation for verified substitute part numbers. No direct cross-references are provided in the available public data; verify compatibility with newer Altera memory controller IP cores if upgrading.
