NDS66PT5-16AT TR

Memory IC Overview

The NDS66PT5-16AT TR is a SDRAM memory IC manufactured by Insignis Technology Corporation. It features a storage capacity of 64Mbit organized as 4M x 16 bits. The device operates with an LVTTL interface and supports a clock frequency of 166 MHz, achieving an access time of 5.4 ns. It functions within a supply voltage range of 3V to 3.6V and is designed for surface mount installation in a 54-TSOP II package (10x22mm). The component is rated for an extended industrial operating temperature range from -40°C to 105°C.

Memory IC Feature Summary

• Supports high-speed parallel data transfer at 166 MHz with 5.4 ns access latency
• Operates reliably across the full industrial temperature spectrum (-40°C to 105°C)
• Compatible with standard LVTTL logic levels for system integration

Memory IC Applications

• Industrial control systems requiring robust memory under extreme temperatures
• Embedded computing platforms utilizing LVTTL interfaces
• Consumer electronics demanding compact surface-mount memory solutions

Memory IC Procurement Notes

Verify the specific suffix 'AT' confirms the -40°C to 105°C temperature rating, distinguishing it from commercial variants. Ensure the TSOP II package dimensions match the PCB footprint requirements. Confirm RoHS compliance status for environmental regulations. Validate that the LVTTL interface aligns with the host controller's voltage levels before procurement.

Memory IC Selection Notes

Select this component when an extended industrial temperature range is mandatory for the application environment. The 16-bit data width suits systems requiring efficient bus utilization without excessive pin counts. Consider the 54-TSOP II package for its balance between density and soldering reliability compared to smaller packages. Ensure the host system supports the required 166 MHz clock speed for optimal performance.

Memory IC Part Context

This part belongs to the NDS66P series of synchronous dynamic random-access memory devices. The series offers various configurations including different densities and package types such as FBGA and TSOP. The NDS66PT5-16AT variant specifically targets applications needing wide temperature tolerance alongside standard LVTTL compatibility, serving as a specialized option within the broader memory portfolio.

Memory IC Replacement Considerations

Cross-reference with NDS66PT5-16IT for identical electrical specifications but verify if the lower temperature range (-40°C to 85°C) meets the application needs. Check for functional equivalents from other manufacturers offering 64Mbit 16-bit SDRAM in 54-TSOP II packages with matching timing parameters.
