NDS73PT9-20IT TR

Memory IC Overview

The NDS73PT9-20IT TR is a Synchronous Dynamic Random Access Memory (SDRAM) integrated circuit manufactured by Insignis Technology Corporation. It provides a storage capacity of 128 Megabits, organized as 4M words by 32 bits. The device operates with an LVTTL interface and supports clock frequencies up to 166 MHz. It is housed in an 86-pin Thin Small Outline Package (TSOP II) with a width of 10.16 mm. The component functions within a supply voltage range of 3V to 3.6V and is rated for an operating temperature range from -40°C to +85°C.

Memory IC Feature Summary

• High-density memory organization providing 128Mb capacity via a 4M x 32 bit structure
• LVTTL interface compatibility for standard logic level integration
• Surface-mount TSOP II packaging designed for automated assembly processes

Memory IC Applications

• Embedded systems requiring volatile data storage
• Industrial control units operating in extended temperature ranges
• Consumer electronics utilizing LVTTL memory interfaces

Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when sourcing. Confirm the manufacturer designation remains Insignis Technology Corporation, noting historical corporate transitions involving Integrated Silicon Solution Inc. Ensure the part number matches the 86-pin TSOP II form factor rather than other variants in the NDS73 series.

Memory IC Selection Notes

Select this component when a 128Mb density with a 32-bit data bus width is required. The 166 MHz speed grade suits applications needing moderate bandwidth. Verify that the system design accommodates the 86-pin footprint and the specific voltage requirements of the LVTTL interface.

Memory IC Part Context

This part belongs to the NDS73P family of SDRAM devices. It shares the 128Mb capacity and 32-bit architecture with other members like the NDS73PT9-16IT TR, differing primarily in speed grades and package availability. The NDS73 series represents a line of low-voltage synchronous DRAMs intended for general-purpose memory applications.

Memory IC Replacement Considerations

NDS73PT9-16IT TR offers identical pinout and capacity but operates at a lower frequency.
