IS34MW04G084-TLI-TR

Memory IC Overview

The IS34MW04G084-TLI-TR is a NAND flash memory component manufactured by ISSI. It features a storage capacity of 512 Mbit organized as 64 M x 8 bits. The device utilizes an asynchronous parallel interface with an 8-bit data bus width. It operates within a supply voltage range of 1.7 V to 1.95 V and supports a maximum active read current of 30 mA. The component is rated for an industrial temperature range from -40°C to +85°C. It is housed in a TSOP-I-48 package.

Memory IC Feature Summary

• Supports low-voltage operation at 1.8V for power efficiency
• Provides pin-compatible replacement for legacy Kioxia TSOP NAND products
• Includes integrated error correction code capabilities

Memory IC Applications

• Industrial control systems requiring low-power non-volatile storage
• Replacement for discontinued Toshiba/Kioxia TSOP NAND flash devices
• Embedded applications operating in wide industrial temperature ranges

Memory IC Procurement Notes

Verify that the target system provides a stable 1.8V power supply, as this model differs from standard 3.3V variants. Confirm compatibility with existing PCB layouts designed for Kioxia TSOP packages, noting that ISSI offers direct pin-to-pin substitution. Ensure the design accounts for the specific ECC requirements associated with this memory type.

Memory IC Selection Notes

Select this part when a 512 Mbit capacity is required in a TSOP-48 form factor with low-voltage constraints. It serves as a direct substitute for Kioxia TH58NVG2S3HTA series parts. Choose the TLI suffix for the -40°C to +85°C industrial temperature grade. Verify that the host controller supports asynchronous parallel access timing compatible with this device.

Memory IC Part Context

This component belongs to the IS34ML/MW series of NAND flash memories from ISSI. The 'MW' designation indicates the 1.8V voltage variant, distinguishing it from the 3.3V 'ML' series. These devices are engineered to replace obsolete NAND flash parts from other manufacturers, specifically targeting the TSOP-48 footprint used in legacy industrial designs.

Memory IC Replacement Considerations

Directly replaces Kioxia TH58NVG2S3HTAxxxxxx models. The ISSI IS34MW04G084-TLI maintains identical pin definitions and electrical characteristics for seamless integration into existing hardware without PCB modifications.
