TMS45169-60DZ

Controllers Overview

The TMS45169-60DZ is a CMOS-based Extended Data Out (EDO) Dynamic Random Access Memory (DRAM) manufactured by Texas Instruments. It provides a memory organization of 256K words by 16 bits, totaling 4 Megabits of storage capacity. The device features a fast access time of 60 nanoseconds, designed for high-speed data retrieval in computing applications. It is housed in a 40-pin Plastic Dual In-line Package (PDIP40), suitable for through-hole mounting on printed circuit boards. The component operates as a standalone memory unit within digital systems.

Controllers Feature Summary

• Extended Data Out (EDO) architecture for improved read cycle efficiency compared to standard DRAM
• CMOS technology ensuring low power consumption and high noise immunity
• Fast 60ns access time supporting high-performance data processing requirements

Controllers Applications

• Computer memory subsystems requiring 16-bit data width
• Embedded systems utilizing EDO DRAM interfaces
• Legacy hardware maintenance and replacement scenarios

Controllers Procurement Notes

Verify RoHS compliance status prior to procurement, as this specific part number may be classified as non-compliant depending on the manufacturing batch and date code. Confirm moisture sensitivity level (MSL 3) handling requirements during storage and assembly. Ensure the supplier provides original manufacturer documentation to validate authenticity, as this is a legacy component with potential availability constraints in the current market.

Controllers Selection Notes

Select this component when a 256Kx16 EDO DRAM configuration is required for system compatibility. The 60ns speed grade must match the host controller's timing specifications. Consider the PDIP40 package constraint for board layout and mechanical integration. Evaluate alternative faster access times if system performance demands exceed 60ns, or verify if lower density options suffice for the application.

Controllers Part Context

This part belongs to the Texas Instruments TMS45169 series of EDO DRAMs. The series offers various speed grades, with the -60 suffix denoting the 60ns access time variant. These components were widely used in personal computers and industrial controllers during the mid-1990s. The TMS45169 series represents a transition period in memory technology, bridging standard DRAM and faster EDO implementations.

Controllers Replacement Considerations

Direct replacements include other TMS45169 variants with different speed grades, such as the TMS45169-70DZ, provided timing margins allow. Cross-brand equivalents from manufacturers like Micron or Samsung offering 256Kx16 EDO DRAMs in compatible packages should be verified for electrical pinout and timing compatibility before substitution.
