TM4100GAD8-80

Overview

The TM4100GAD8-80 is a dynamic RAM module manufactured by Texas Instruments. It provides a total memory capacity of 4,194,304 bytes organized as a 524,288-word by 8-bit configuration. The component features an access time of 80 nanoseconds, indicated by the suffix -80 in its part number. This module utilizes standard DRAM technology suitable for general-purpose data storage applications requiring high-density memory solutions.

Feature Summary

• Provides high-density data storage with a 4 Mbyte capacity
• Features 8-bit data width for parallel data processing
• Designed as a dynamic random-access memory module

Applications

• General-purpose data storage systems
• Embedded computing environments
• Industrial control memory modules

Procurement Notes

Verify the specific access speed and package type against the manufacturer's official datasheet before procurement. Ensure compatibility with system voltage requirements and interface specifications. Confirm that the -80 speed grade meets the timing constraints of the target application design.

Selection Notes

Select this component when a 4 Mbyte DRAM module with 8-bit width is required. The 80 ns access time defines the performance ceiling for read/write operations. Compare against other speed grades if higher throughput is necessary, or verify pinout compatibility with existing board layouts.

Part Context

Texas Instruments produces various memory modules under the TM4100 series. These components are designed to offer reliable data retention and access for embedded systems. The series includes variations in bit-width and access speeds to suit different architectural needs within the TI product portfolio.

Replacement Considerations

Check for equivalent DRAM modules from Texas Instruments or other manufacturers offering identical 4 Mbyte capacity and 8-bit width. Verify that alternative parts match the 80 ns access time requirement and physical package dimensions for direct substitution.
