NDS76PBA-20ET TR

Memory IC Overview

The NDS76PBA-20ET TR is a Synchronous Dynamic Random Access Memory (SDRAM) integrated circuit manufactured by Insignis Technology Corporation. It provides a storage capacity of 128 Megabits, organized as 8 Megawords by 16 bits. The device operates with an LVTTL interface and supports a clock frequency of 200 MHz, achieving a typical access time of 4.5 nanoseconds. It functions within a supply voltage range of 3V to 3.6V and is housed in a 54-pin Thin-Shrink Small Outline Package (TSOP II).

Memory IC Feature Summary

• Supports high-speed data transfer via a 200 MHz clock frequency.
• Utilizes Low Voltage Transistor-Transistor Logic (LVTTL) for standard digital interfacing.
• Features a compact surface-mount package suitable for space-constrained designs.

Memory IC Applications

• Portable electronic devices requiring volatile memory storage.
• Embedded systems utilizing LVTTL-compatible controllers.
• Consumer electronics with limited board real estate.

Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when sourcing. Confirm that the 'ET' designation corresponds to the required speed grade and temperature range for your application. Ensure compatibility with the 54-pin TSOP II footprint during PCB layout. Cross-reference the manufacturer's latest datasheet for any updates on moisture sensitivity levels or RoHS compliance status before finalizing procurement.

Memory IC Selection Notes

Select this component when a 128Mb density is required with a 16-bit data width. The 4.5 ns access time at 200 MHz suits applications needing moderate latency. The LVTTL interface simplifies integration with legacy or standard logic controllers. Consider the TSOP II package if leadless BGA options are unavailable or if through-hole compatibility is not needed but low profile is desired.

Memory IC Part Context

This part belongs to the NDS76 series of SDRAMs from Insignis Technology Corporation. The series typically offers various densities and speeds. The NDS76PBA-20ET TR specifically denotes the 128Mb variant with the 200 MHz speed bin and tape-and-reel packaging. It serves as a volatile memory solution for general-purpose computing tasks where data retention is not permanent.

Memory IC Replacement Considerations

Check for direct substitutes such as the NDS76PT5-20IT TR, which shares similar electrical characteristics but uses a different package type. Verify pin-to-pin compatibility if replacing within the same family. Ensure any alternative maintains the 16-bit organization and LVTTL interface requirements.
