IS25LP064D-JWLE – Serial NOR Flash – ISSI

The ISSI IS25LP064D-JWLE is a 64Mbit (8M x 8) serial NOR Flash memory with SPI, Dual, Quad and QPI interface and a 2.30V–3.60V supply, supplied as Known Good Die (KGD) per the ISSI "W" package code. Available now for RFQ from Pacific Component Xchange.

The ISSI IS25LP064D-JWLE is a 64-megabit (8M x 8) Serial NOR Flash memory from the IS25LP064D family by Integrated Silicon Solution Inc. (ISSI). It delivers a versatile, high-performance code- and data-storage solution for systems that demand low power consumption and a flexible serial interface. The device is accessed through a standard 4-wire SPI interface (SI, SO, SCK, CE#) that can be extended to Dual I/O, Quad I/O, and QPI operation, with fast read clock frequencies up to 166MHz (STR) and Double Transfer Rate (DTR) support up to 80MHz, enabling effective throughput well beyond a basic single-line SPI design.

The IS25LP064D operates from a 2.30V to 3.60V supply and supports Standard SPI, Fast Read, Dual Output/Dual I/O, Quad Output/Quad I/O, SPI DTR, and QPI modes. The memory array supports uniform 4 Kbyte sector, 32 Kbyte block, and 64 Kbyte block erase, plus full chip erase, with page programming of 1 to 256 bytes. Advanced sector/block protection, software and hardware reset, program/erase suspend & resume, and Serial Flash Discoverable Parameters (SFDP) support round out a robust feature set for embedded designs.

Per the ISSI part-number scheme (Rev. A5 datasheet), the -JWLE suffix decodes as: J = Standard option, W = KGD (Known Good Die, Call Factory), L = RoHS compliant, and E = Extended temperature grade (−40°C to +105°C). This is a bare-die (KGD) offering intended for module makers, multi-chip packages, and specialized assemblies rather than a conventional packaged SOIC or WSON part.

Why Source IS25LP064D-JWLE from Pacific Component Xchange

The IS25LP064D-JWLE is a scarce, factory-order (KGD) variant with little to no authorized-distributor stock, making it difficult to source through conventional channels. Pacific Component Xchange is an independent distributor specializing in hard-to-find, allocated, and obsolete memory. We help engineering, procurement, and EOL teams secure the exact ISSI Serial NOR Flash they need to keep production lines running and legacy systems supported.

Every order is backed by rigorous quality and counterfeit-avoidance processes, inspection, and authenticity verification, with global shipping to keep your build schedule on track.
