Controllers Procurement Notes

Verify the specific suffix 'DR' to confirm the tape-and-reel packaging format and ensure compatibility with surface-mount assembly lines. Confirm that the 70ns speed grade meets system timing requirements. Check for RoHS compliance status if environmental regulations apply to your manufacturing process. Ensure proper ESD handling procedures are followed during storage and installation.

Controllers Selection Notes

Select this component when a 1M-bit DRAM solution with fast page mode access is required. The 70ns speed rating suits applications needing moderate-to-high data throughput. Consider the SOIC or similar surface-mount package availability for PCB layout constraints. Evaluate power supply stability needs associated with CMOS DRAM operation.

Controllers Part Context

This part belongs to the TMS44400 series of Fast Page DRAMs from Texas Instruments. These components were designed for use in early personal computers and embedded systems requiring reliable, high-density volatile memory. The series represents a transition period in semiconductor memory technology, offering improved performance over earlier static RAM solutions while maintaining cost-effectiveness.

Controllers Replacement Considerations

Check for direct pin-compatible substitutes within the TMS44400 family, such as the TMS44400-70DJ, verifying identical electrical characteristics and pinout configurations before substitution.
