TMS45169-70DZ

Overview

The TMS45169-70DZ is a CMOS EDO DRAM memory controller manufactured by Texas Instruments. It features a 256K x 16 bit organization, providing a total capacity of 4 Mbits. The device operates with a 70 ns access time and is housed in a 40-pin PDSO package. This component is designed for high-performance data acquisition and building automation applications, offering efficient memory management capabilities within the specified electrical parameters.

Feature Summary

• EDO DRAM architecture for enhanced data throughput
• CMOS technology for low power consumption
• Integrated memory controller functionality

Applications

• Data acquisition systems
• Building automation controllers
• High-performance analog control interfaces

Procurement Notes

Verify RoHS compliance status as sources indicate non-compliance. Confirm package type is PDSO-40. Ensure the 70 ns speed grade matches system timing requirements. Check for active status availability through authorized distributors.

Selection Notes

Select this part for applications requiring 4 Mbit EDO DRAM integration. Compare against TMS45169-60DZ if faster 60 ns access is needed. Ensure voltage levels and interface compatibility with the host microcontroller or processor are validated before integration.

Part Context

This component belongs to the Texas Instruments TMS45169 series of EDO DRAMs. It shares the 256K x 16 organization with other variants like the TMS45169P-70DZ but differs in specific suffix designations. The series is positioned for industrial and commercial control environments requiring reliable memory storage.

Replacement Considerations

The TMS45169-60DZ is a confirmed substitute with identical organization but 60 ns speed. Verify pinout compatibility when replacing with other TMS45169 series members.
