NDS73PT9-20AT TR

Memory IC Overview

The NDS73PT9-20AT TR is a high-speed CMOS synchronous dynamic random-access memory (SDRAM) manufactured by Insignis Technology Corporation. It provides a total storage capacity of 128 Mbits, internally organized as four independent banks of 1 Megabit by 32 bits. The device operates with an LVTTL interface and supports clock frequencies up to 200 MHz. It is housed in an 86-pin TSOP II package with dimensions of 10x22 mm. The component functions within a supply voltage range of 3V to 3.6V and is rated for industrial operating temperatures between -40°C and 105°C.

Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when sourcing. Confirm the manufacturer is Insignis Technology Corporation, as part numbers may appear across multiple distributor databases. Ensure the order matches the exact 86-TSOP II package type. Check current availability status as supply constraints may affect fulfillment timelines for this specific variant.

Memory IC Selection Notes

Select this component when a 128Mb density with a 32-bit data width is required. The 200 MHz speed class distinguishes it from slower variants like the 166 MHz models. The LVTTL interface dictates compatibility with specific logic families. Consider the 86-pin TSOP II footprint for PCB layout constraints. Verify that the -40°C to 105°C temperature range meets the target application's thermal requirements.

Memory IC Part Context

This part belongs to the NDS73 series of SDRAMs from Insignis Technology Corporation. The series includes various speed grades and package options, such as the NDS73PT9-16IT TR which operates at 166 MHz. The NDS73PT9-20AT TR represents the higher performance tier within this family, offering increased clock frequency while maintaining the same memory organization and interface standards.

Memory IC Replacement Considerations

Direct substitutes include other NDS73PT9-20AT TR units from the same manufacturer. Cross-referencing with similar 128Mb 32-bit SDRAMs requires verifying pinout compatibility and timing parameters. Alternative packages like FBGA variants exist within the broader NDS73 family but require adapter solutions.
