NDS38PT5-16ET

Memory IC Overview

The NDS38PT5-16ET is a 256Mbit Synchronous Dynamic Random Access Memory (SDRAM) manufactured by Insignis Technology Corporation. It features an LVTTL memory interface and operates at a clock frequency of 166 MHz. The device is organized as 32M x 8 bits and supports surface mount installation in a 54-TSOP II package. It functions within a supply voltage range of 3V to 3.6V and is rated for commercial operating temperatures from 0°C to 70°C.

Memory IC Feature Summary

• Supports burst read/write access with programmable burst lengths
• Includes automatic refresh functionality for data retention
• Utilizes high-speed CMOS technology for efficient operation

Memory IC Applications

• Embedded systems requiring synchronous DRAM
• Consumer electronics with limited power budgets
• Industrial control units needing reliable volatile storage

Memory IC Procurement Notes

Verify the specific suffix 'ET' indicates the extended temperature or testing variant compared to standard industrial versions. Confirm package availability in Tape & Reel format if automated assembly is required. Ensure compatibility with LVTTL logic levels in the target design. Check RoHS compliance status for environmental regulations. Validate lead times due to potential supply constraints mentioned for similar components.

Memory IC Selection Notes

Select this component when a 256Mbit capacity with 8-bit width is required. Choose based on the 166 MHz speed grade for higher bandwidth needs. Consider the 54-TSOP II package for space-constrained PCB layouts. Verify that the 0°C to 70°C operating range meets the application's thermal requirements. Compare against the NDS36PT5 series if 16-bit width is preferred instead.

Memory IC Part Context

This part belongs to the NDS36/NDS38 family of SDRAMs from Insignis Technology Corporation. The NDS38 designation typically denotes an 8-bit organization, whereas the NDS36 series offers 16-bit organization. Both share similar core technologies but differ in data bus width and internal bank configuration. This family targets cost-sensitive embedded applications requiring moderate performance.

Memory IC Replacement Considerations

The NDS38PT5-16IT is a verified substitute with identical electrical specifications but an extended industrial temperature range (-40°C to 85°C). Ensure pin compatibility remains unchanged during substitution. Verify that the temperature rating of the replacement matches the system's operational environment.
