Memory IC datasheet and documents for IS43DR16640B-25DBLI-TR

IS43DR16640B-25DBLI-TR

Memory IC Overview

The IS43DR16640B-25DBLI-TR is a 1Gb (64M x 16) DDR2 SDRAM manufactured by ISSI. It features an 84-ball TW-BGA package and supports clock frequencies up to 400MHz with a 1.8V supply voltage. The device includes eight internal banks, a 4-bit prefetch architecture, and programmable CAS latencies ranging from 3 to 7. Key specifications include SSTL_1.8 interface compatibility, On-Die Termination (ODT), and support for Partial Array Self Refresh (PASR).

Memory IC Feature Summary

Supports concurrent operations across eight internal banks.
Features a 4-bit prefetch architecture for high-speed data transfer.
Includes On-Die Termination (ODT) for signal integrity.
Offers Partial Array Self Refresh (PASR) for power management.

Memory IC Applications

General-purpose memory systems requiring DDR2 SDRAM.
Embedded applications utilizing the 84-ball TW-BGA form factor.
Industrial environments supporting specified temperature ranges.

Memory IC Procurement Notes

Verify that the ordering suffix '-TR' corresponds to tape-and-reel packaging as indicated by distributor listings. Confirm the specific speed grade matches system timing requirements. Ensure the component meets RoHS compliance standards required for your assembly process. Cross-reference the manufacturer part number with official datasheets to validate electrical characteristics before finalizing procurement.

Memory IC Selection Notes

Select this component when a 1Gb density with a 16-bit data bus width is required. The 84-ball TW-BGA package is suitable for space-constrained designs. Consider the 400MHz maximum frequency and 1.8V operating voltage for power and performance alignment. Verify that the industrial or automotive temperature grades meet environmental constraints.

Memory IC Part Context

This part belongs to the IS43/46DR16640B series of 1Gb DDR2 SDRAMs. It shares architectural similarities with other members of the family but differs in organization, package type, and specific speed grades. The 'IS43' prefix typically denotes commercial or industrial grade devices, while the 'B' indicates the specific revision or feature set within the DDR2 product line.
