NDS66PT5-20AT TR

Memory IC Overview

The NDS66PT5-20AT TR is a SDRAM memory IC manufactured by Insignis Technology Corporation. It features a storage capacity of 64Mbit organized as 4M x 16. The device utilizes an LVTTL parallel interface and operates at a clock frequency of 200 MHz with a 4.5 ns access time. It is housed in a 54-TSOP II package, measuring 10x22 mm with a height of 1.2 mm. The component supports a supply voltage range of 3V to 3.6V and functions within a temperature range of -40°C to 105°C.

Memory IC Feature Summary

• Supports high-speed data transfer via a 200 MHz LVTTL parallel interface
• Designed for robust operation across extended industrial temperature ranges
• Provides compact surface-mount integration using the 54-TSOP II package

Memory IC Applications

• Computer systems requiring volatile memory expansion
• Server infrastructure components
• Networking equipment utilizing high-speed data processing

Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm the operating temperature grade matches the application requirements, as variants exist for different thermal environments. Ensure the LVTTL interface compatibility aligns with the host controller logic levels. Validate the 54-TSOP II footprint dimensions against the PCB layout specifications prior to procurement.

Memory IC Selection Notes

Select this component for designs requiring 64Mbit density with LVTTL compatibility. Consider the 200 MHz speed rating for bandwidth-intensive tasks. Evaluate the 54-TSOP II package for space-constrained layouts. Compare against other NDS66P series variants if different speed grades or package types are needed. Ensure the 3V to 3.6V supply voltage fits the system power architecture.

Memory IC Part Context

This part belongs to the NDS66P series of SDRAM devices from Insignis Technology Corporation. The series offers various speed grades and package options, including FBGA and TSOP II configurations. The NDS66PT5-20AT TR specifically targets applications needing reliable volatile memory with standard LVTTL signaling. It complements other parts like the NDS66PT5-16IT which offers lower speed ratings.

Memory IC Replacement Considerations

Direct substitutes include other NDS66PT5-20AT units from the same manufacturer. Verify pinout and electrical characteristics match exactly before swapping. Cross-reference with NDS66PBA-20IT if FBGA packaging is acceptable instead of TSOP II.
