NDS73PT9-16AT

Memory IC Overview

The NDS73PT9-16AT is a SDRAM memory IC manufactured by Insignis Technology Corporation. It features a storage capacity of 128Mb organized as 4M x 32. The device utilizes an LVTTL interface and operates at a clock frequency of 166 MHz. It is supplied in an 86-TSOP II package with dimensions of 0.400 inches (10.16mm) width. The component supports a supply voltage range of 3V to 3.6V and functions within an ambient temperature range of -40°C to 85°C.

Memory IC Feature Summary

• Provides high-density volatile memory storage using SDRAM technology for data retention during power.
• Supports parallel data access via a wide 32-bit LVTTL interface for system compatibility.
• Operates at a clock frequency of 166 MHz to facilitate rapid data transfer rates.
• Designed for surface mount installation in compact electronic assemblies.

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific suffix 'AT' against official manufacturer documentation to confirm exact speed grade and temperature rating variations. Ensure the 86-TSOP II footprint matches the target PCB design. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration into the manufacturing process.

Memory IC Selection Notes

Select this component when a 128Mb density with a 32-bit data bus width is required. The LVTTL interface dictates compatibility with legacy or specific logic families. The 166 MHz speed rating suits applications needing moderate bandwidth without higher-speed DDR alternatives. Verify that the 3V to 3.6V supply range aligns with the system power architecture.

Memory IC Part Context

This part belongs to the NDS73 series of SDRAM devices from Insignis Technology Corporation. The series includes variants with different pin counts, such as the 54-pin TSOP II options found in the NDS36P family. The NDS73 series specifically targets applications requiring wider data buses compared to narrower 16-bit configurations.

Memory IC Replacement Considerations

Direct substitutes include the NDS73PT9-16ET variant, which shares the same package and organization but may differ in electrical testing parameters. Cross-reference the NDS73PT9-16IT TR for identical functional specifications if available. Verify pin-to-pin compatibility before substitution.
