IS43DR16128C-3DBLI-TR

Memory IC Overview

The IS43DR16128C-3DBLI-TR is a 2 Gbit DDR2 SDRAM manufactured by ISSI. It features a 16-bit data bus width and an organization of 128M x 16. The component supports a maximum clock frequency of 333 MHz with a typical access time of 450 ps. It operates within a voltage range of 1.7 V to 1.9 V. The device is housed in an 84-ball BGA package measuring 8 mm x 12.5 mm. It is designed for industrial temperature ranges, functioning between 0°C and +85°C.

Memory IC Feature Summary

• Supports high-speed parallel data transfer via a 16-bit interface at frequencies up to 333 MHz.
• Provides 2 Gbit storage capacity organized as 128 megawords by 16 bits.
• Operates on a standard 1.8V power supply with specified tolerance limits.

Memory IC Applications

• Industrial embedded systems requiring non-volatile-like persistence or large buffer memory.
• Automotive infotainment and control units operating within industrial temperature grades.
• Telecommunications equipment utilizing DDR2 interfaces for data processing.

Memory IC Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging when ordering. Confirm the exact temperature grade (IT) matches the application's thermal requirements. Ensure the 84-ball BGA footprint aligns with the PCB design. Check for RoHS compliance documentation if required by regional regulations. Validate that the 1.8V supply rail stability meets the component's electrical specifications.

Memory IC Selection Notes

Select this part when a 2 Gbit density is required with a 16-bit interface width. Consider the 333 MHz speed grade for applications needing moderate bandwidth. The industrial temperature range makes it suitable for harsh environments compared to commercial variants. The BGA-84 package offers a compact form factor for space-constrained designs. Verify compatibility with existing DDR2 controllers supporting CL5 timing parameters.

Memory IC Part Context

This component belongs to the IS43DR16128C series of DDR2 SDRAMs from ISSI. It shares architectural similarities with other members of the family but differs in capacity and speed grades. The series is designed for general-purpose memory applications requiring reliable performance. It complements ISSI's broader portfolio of static and dynamic random-access memories.

Memory IC Replacement Considerations

Check for direct substitutes within the IS43DR16128C series with different speed or temperature ratings. Verify pin-to-pin compatibility with other 84-ball BGA DDR2 devices from ISSI. Cross-reference with other manufacturers offering 2Gbit 16-bit DDR2 parts in similar packages. Ensure electrical characteristics match before substituting.
