NDS38PT5-20ET

Memory IC Overview

The NDS38PT5-20ET is a Synchronous Dynamic Random Access Memory (SDRAM) integrated circuit manufactured by Insignis Technology Corporation. It provides a storage capacity of 256 Megabits, organized as 32 Megawords by 8 bits. The device operates with a clock frequency of 200 MHz and utilizes an LVTTL interface. It functions within a supply voltage range of 3V to 3.6V and supports an operating temperature range of 0°C to 70°C. The component is housed in a 54-pin Thin Small Outline Package II (TSOP II) with dimensions of 10mm x 22mm.

Memory IC Feature Summary

• High-speed data access capabilities enabled by a 200 MHz clock frequency
• Compatibility with Low Voltage Transistor-Transistor Logic (LVTTL) interfaces
• Surface-mount construction utilizing a compact 54-pin TSOP II package

Memory IC Applications

• Embedded memory systems requiring high-speed synchronous access
• Consumer electronics devices utilizing LVTTL logic families
• Industrial control units operating within standard commercial temperature ranges

Memory IC Procurement Notes

Verify the specific suffix ET against official manufacturer documentation to confirm the extended temperature rating and testing specifications. Ensure compatibility with LVTTL signal levels and 3V to 3.6V power supplies. Confirm the 54-pin TSOP II footprint matches the target PCB design. Cross-reference the 200 MHz speed grade with system timing requirements to ensure proper operation.

Memory IC Selection Notes

Select this component when a 256Mb density is required alongside a 200 MHz operational speed. The LVTTL interface dictates compatibility with specific logic families. The 0°C to 70°C operating range defines the environmental constraints for deployment. The 54-pin TSOP II package determines the physical layout and soldering process requirements for surface mount assembly.

Memory IC Part Context

This part belongs to the NDS38P series from Insignis Technology Corporation, a manufacturer specializing in DRAM solutions. The series includes variants with different bit organizations and speed grades. The NDS38PT5-20ET specifically denotes the 8-bit organization variant with the extended test specification, distinguishing it from other members like the NDS36PT5-16IT which features a 16-bit organization and lower clock speed.

Memory IC Replacement Considerations

Direct substitutes must match the 256Mb capacity, 200 MHz speed, LVTTL interface, and 54-TSOP II package. Verify that alternative sources provide the same ET designation for extended testing and temperature compliance. Check for pin-to-pin compatibility and identical electrical characteristics before integration.
