AM2976JC

Overview

The AM2976JC is a Dynamic RAM (DRAM) Memory Controller IC manufactured by Advanced Micro Devices. It operates within a supply voltage range of 4.5V to 5.5V and supports an operating temperature range of 0°C to 70°C (TA). The device is housed in a 28-PLCC package, specifically a 28-LCC with J-leads, measuring approximately 11.51x11.51 mm. It is designed for surface mount installation and remains an active product in the manufacturer's portfolio.

Feature Summary

• Functions as a dedicated controller for dynamic random-access memory systems
• Utilizes a 28-pin plastic leaded chip carrier package for surface mounting
• Operates on standard single-supply voltage levels compatible with 5V logic families

Applications

• Dynamic RAM memory subsystem control
• Computer system memory architecture integration
• Industrial control systems requiring DRAM interfacing

Procurement Notes

Verify the specific manufacturer source, as the component history involves Advanced Micro Devices and subsequent Xilinx branding. Confirm the exact package variant matches the 28-PLCC specification. Ensure the operating temperature grade aligns with commercial requirements. Check for RoHS compliance status if required by current manufacturing standards. Validate part authenticity through authorized distribution channels.

Selection Notes

Select this component when a dedicated hardware solution for DRAM management is required within the specified voltage and thermal constraints. The 28-PLCC package suits applications where surface mount technology is preferred over through-hole. Consider the active status of the part for long-term production viability. Evaluate interface compatibility with the target memory devices before finalizing the design.

Part Context

This integrated circuit belongs to the family of memory controllers produced by Advanced Micro Devices. It serves as a bridge between the system processor and DRAM modules. The designation reflects its role in managing data flow and timing signals for volatile memory storage components in computing environments.

Replacement Considerations

The AM29C668-1JC is identified as a related dynamic memory controller/driver from the same manufacturer lineage. Verify pinout and functional compatibility before substitution.
