NDS38PT5-16IT

Memory IC Overview

The NDS38PT5-16IT is a 256 Mbit Synchronous Dynamic Random Access Memory (SDRAM) manufactured by Insignis Technology Corporation. It operates with an LVTTL interface and supports clock frequencies up to 166 MHz. The device is internally organized as 4 banks of 4M words by 8 bits, providing a total capacity of 256 Megabits. It functions within a supply voltage range of 3.0V to 3.6V and is rated for industrial operating temperatures from -40°C to +85°C. The component is housed in a 54-pin Thin Small Outline Package (TSOP II) with a width of 10.16mm.

Memory IC Feature Summary

• High-speed synchronous DRAM technology utilizing CMOS processes for efficient data access.
• Internal organization into four independent banks allows for concurrent operation modes.
• Supports low voltage TTL logic levels for direct interface with standard digital systems.
• Industrial temperature rating ensures reliable performance in demanding environmental conditions.

Memory IC Applications

• Embedded memory systems requiring high-speed data buffering
• Industrial control units operating in wide temperature ranges
• Consumer electronics utilizing LVTTL interfaces

Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging if bulk handling is required. Confirm RoHS3 compliance status for environmental regulations. Ensure the 54-TSOP II footprint matches the target PCB design. Check for any specific moisture sensitivity level requirements during assembly. Validate that the LVTTL interface aligns with the host controller's voltage standards.

Memory IC Selection Notes

Select this part when a 256 Mbit density is required with an 8-bit data bus width. The 166 MHz speed class suits applications needing moderate to high bandwidth. The TSOP II package is suitable for space-constrained surface mount designs. Consider the 4-bank architecture for improved throughput compared to single-bank alternatives. Ensure the system power supply can maintain stability within the 3.0V to 3.6V range.

Memory IC Part Context

This component belongs to the NDS38 series of SDRAM devices from Insignis Technology Corporation. It shares architectural similarities with other parts in the family but differs in organization and pinout configurations. The series is designed for general-purpose memory applications where cost-effective high-speed storage is necessary. It complements other offerings like the NDS36 series which may offer different bit widths or organizations.

Memory IC Replacement Considerations

Direct substitutes include other 256Mb LVTTL SDRAMs in 54-TSOP II packages. Verify compatibility with existing board layouts and signal integrity requirements. Cross-reference electrical specifications such as access times and power consumption. Ensure the replacement maintains the same bank structure and command set compatibility.
