NDS66PBA-16AT TR

Memory IC Overview

The NDS66PBA-16AT TR is a 64 Mbit SDRAM memory IC manufactured by Insignis Technology Corporation. It features an LVTTL interface and operates at a clock frequency of 166 MHz with a 5.4 ns access time. The device is organized as 4M x 16 bits and is housed in a 54-FBGA (8x8) surface-mount package. It supports a supply voltage range of 3V to 3.6V and functions within an ambient temperature range of -40°C to 105°C.

Memory IC Feature Summary

• Supports PC166 speed grade for high-frequency data transfer
• Automotive-grade thermal stability up to 105°C
• LVTTL compatible interface for standard logic integration

Memory IC Applications

• Automotive electronic systems requiring extended temperature operation
• Embedded memory solutions for industrial control units
• Consumer electronics utilizing LVTTL-based architectures

Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates Tape & Reel packaging, distinct from tray variants. Confirm the 'AT' designation aligns with the required -40°C to 105°C automotive temperature range. Ensure compatibility with existing PCB footprints for the 54-FBGA package before finalizing orders.

Memory IC Selection Notes

Select this component when an automotive-rated SDRAM solution is required for space-constrained designs. The 54-FBGA package offers a compact footprint suitable for dense layouts. Verify that the system design supports LVTTL signaling levels and the specified 3V to 3.6V power supply constraints.

Memory IC Part Context

This part belongs to the NDS66 series of SDRAM devices from Insignis Technology Corporation. The series includes various speed grades and temperature ranges, with the 'AT' variant specifically engineered for automotive applications requiring robust thermal performance alongside standard SDR memory functionality.

Memory IC Replacement Considerations

Direct substitutes include other NDS66PBA-16AT variants from the same manufacturer. Cross-referencing with equivalent PC166 SDRAM parts from other vendors requires careful verification of pinout compatibility and electrical specifications.
