IS25WP040D-JNLE – Serial NOR Flash – ISSI

The ISSI IS25WP040D-JNLE is a 4Mbit (512KB) 1.8V serial NOR Flash memory featuring a 133MHz multi-I/O SPI and Quad-I/O QPI interface in an 8-pin SOIC (150 mil) package, extended temperature grade.

The IS25WP040D-JNLE from ISSI (Integrated Silicon Solution, Inc.) is a 4Mbit (512Kbyte) low-voltage Serial NOR Flash memory from the IS25WP family. It operates on a single 1.65V to 1.95V supply and delivers high-throughput non-volatile storage through a 133MHz Multi-I/O SPI and Quad-I/O QPI interface, making it well suited to space- and power-constrained embedded designs that need fast code-shadow or configuration storage.

This ordering option is supplied in an 8-pin SOIC (150 mil) package with RoHS-compliant (Lead-free, Halogen-free) finish and the Extended temperature grade (-40°C to +105°C). The Rev-D die supports standard SPI, Fast Read, Dual, Dual I/O, Quad, Quad I/O, SPI DTR, Dual/Quad I/O DTR and QPI modes, plus Serial Flash Discoverable Parameters (SFDP).

Key Features

• Density: 4 Mbit (512 Kbyte)
• Interface: 133MHz Multi-I/O SPI and Quad-I/O (QPI); SPI/Dual/Quad DTR up to 66MHz
• Read speed: 50MHz Normal Read, 133MHz Fast Read (equivalent 532MHz / 66 Mbytes/s throughput in QPI)
• Single supply voltage: 1.65V to 1.95V (1.8V class)
• Page program: 256 bytes per programmable page (1 to 256 bytes per command)
• Uniform erase architecture: 4Kbyte sectors, 32Kbyte / 64Kbyte blocks, and full chip erase
• SFDP support

• Retention: more than 20 years
• Low power: 10 mA active read current, 8 µA standby current
• Package: 8-pin SOIC (150 mil), RoHS compliant, Extended temperature -40°C to +105°C

Applications

• Embedded code storage and boot/firmware shadowing for microcontrollers and SoCs
• IoT and wearable devices requiring low-voltage, low-power non-volatile memory
• Networking and industrial control configuration storage
• Consumer electronics, set-top boxes and digital peripherals
• FPGA/CPLD configuration and lookup-table storage

Why Source IS25WP040D-JNLE from Pacific Component Xchange

The IS25WP040D-JNLE is a hard-to-find, low-availability part with limited authorized-distributor stock. As an independent distributor specializing in obsolete and hard-to-find memory, Pacific Component Xchange helps engineers and procurement teams secure end-of-life and allocation-constrained devices without redesigning around a discontinued part. We support quantity requirements through our global sourcing network.

Every order is backed by our authenticity and quality screening to mitigate counterfeit risk, with worldwide shipping for prototype through production volumes. Because pricing on scarce parts moves with the market, this is a Request-For-Quote item. Contact Pacific Component Xchange today to request a quote on IS25WP040D-JNLE and lock in availability for your build.
