Procurement Notes

Verify the specific suffix R-80 against official Texas Instruments documentation to confirm the 80ns speed grade. Ensure compatibility with existing motherboard socket types and voltage requirements before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Confirm that the bulk packaging matches your assembly line handling capabilities.

Selection Notes

Select this module when a wide 36-bit data interface is required alongside fast memory access speeds. Consider the physical dimensions and pin configuration to ensure mechanical fit within the target enclosure. Evaluate power consumption characteristics relative to the system's thermal management capabilities. Compare against alternative modules if different access times or organizations better suit the application constraints.

Part Context

This component belongs to the Texas Instruments DRAM module family, designed for embedded and industrial applications. It represents a consolidated memory solution replacing discrete chip implementations. The module simplifies PCB layout by reducing the number of individual components needed for memory expansion in complex digital systems.

Replacement Considerations

The TM248NBK36R-70 is a documented variant with faster 70ns access time. Verify electrical compatibility and pinout equivalence before substitution. Ensure the replacement meets all timing and voltage specifications of the original design.
