TMS626402-12DGE

Overview

The TMS626402-12DGE is a memory controller IC manufactured by Texas Instruments. It is classified as a synchronous DRAM component with a configuration of 4MX4. The device is housed in a PDSO44 package, indicating a plastic dual small-outline package with 44 leads. This integrated circuit serves as a dedicated controller for managing synchronous dynamic random-access memory operations within electronic systems.

Feature Summary

• Functions as a dedicated memory controller IC for system integration
• Designed specifically for synchronous DRAM architectures
• Utilizes a 4MX4 memory organization structure
• Packaged in a standard PDSO44 form factor

Applications

• Synchronous DRAM interface management
• Memory subsystem control in embedded systems
• Digital logic circuits requiring SDRAM coordination

Procurement Notes

Verify the exact manufacturer part number against official Texas Instruments documentation to ensure authenticity. Confirm that the PDSO44 package type matches your board layout requirements. Check for specific suffix variations if available in official catalogs, as these may indicate minor manufacturing revisions without altering core functionality. Ensure compliance with relevant RoHS directives if required for your assembly process.

Selection Notes

Select this component when a dedicated controller for 4MX4 synchronous DRAM is required. The PDSO44 package dictates the physical footprint and pinout compatibility on the printed circuit board. Consider the synchronous nature of the memory interface when designing timing constraints. Verify that the system architecture supports the specific memory organization defined by this controller IC.

Part Context

This component belongs to the broader category of controllers and memory ICs produced by Texas Instruments. It is distinct from general-purpose logic or power management devices, focusing solely on memory interface control. The designation indicates its role in handling synchronous dynamic random-access memory signals within digital systems.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Consult official Texas Instruments cross-reference tools or authorized distributor databases for verified equivalents. Do not assume functional interchangeability with other memory controllers without explicit manufacturer confirmation.
