Controllers Procurement Notes

Verify the specific suffix 'DJ' confirms the PDSO20 plastic small outline package and lead-free status. Confirm the '10' designation indicates the 100 ns speed grade. Ensure the component status is listed as Active in current manufacturer catalogs to guarantee long-term availability and supply chain stability for production runs.

Controllers Selection Notes

Select this component when a 256K x 4 bit DRAM configuration is required with 100 ns access times. Consider the PDSO20 package constraints for PCB layout. Evaluate power consumption requirements against standard CMOS DRAM profiles. Compare pin compatibility with existing board designs if replacing legacy components.

Controllers Part Context

This part belongs to the TMS44C256 series of high-speed DRAMs from Texas Instruments. It shares architectural similarities with the TMS44C257 but differs in organization. The series represents a generation of CMOS memories designed to replace older NMOS counterparts, offering lower power consumption while maintaining high performance levels suitable for general-purpose computing tasks.

Controllers Replacement Considerations

Check for direct equivalents such as the TMS44C256-10N or other manufacturers' 256Kx4 DRAMs in SOP20 packages. Verify electrical compatibility regarding access times and voltage levels before substitution.
