NDS73PT9-20IT

Memory IC Overview

The NDS73PT9-20IT 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 4 Megawords by 32 bits. The device operates with an LVTTL interface and supports a clock frequency of 200 MHz. It is housed in an 86-pin TSOP II package with dimensions of 0.400 inches (10.16 mm) width. The component functions within a supply voltage range of 3V to 3.6V and is rated for an operating temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports high-speed data transfer via a 200 MHz clock frequency
• Utilizes Low Voltage Transistor-Transistor Logic (LVTTL) interface standards
• Designed for surface mount installation in compact electronic assemblies

Memory IC Applications

• Embedded systems requiring volatile memory storage
• Industrial control equipment operating in wide temperature ranges
• Internet of Things (IoT) devices needing reliable data retention during operation

Memory IC Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm pinout compatibility and electrical characteristics. Ensure that the procurement channel provides original components with traceable manufacturing dates. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into production workflows.

Memory IC Selection Notes

Select this component when a 128Mb density with a 32-bit word width is required for synchronous memory applications. The 200 MHz speed rating suits designs demanding higher bandwidth than standard lower-frequency alternatives. The industrial temperature range makes it suitable for environments where standard commercial grade parts may fail due to thermal stress.

Memory IC Part Context

This part belongs to the NDS73 series of SDRAM products from Insignis Technology Corporation. The series includes variants with different speed grades and package options, such as the NDS73PT9-16IT which operates at 166 MHz. The manufacturer specializes in DRAM design and fabrication, offering memory solutions tailored for specific embedded and industrial market needs.

Memory IC Replacement Considerations

The NDS73PT9-16IT serves as a compatible alternative within the same product family, offering identical memory organization and package type but with a reduced clock frequency of 166 MHz. Verify that the system timing constraints can accommodate the slower speed before substituting.
