IS25WQ040-JNLE(R) – Serial NOR Flash – ISSI
The ISSI IS25WQ040-JNLE(R) is a 4Mbit (512K x 8) 1.8V Quad Serial (SPI/QPI) NOR Flash memory in an 8-pin SOIC/SOP package, rated for the industrial -40C to +105C temperature range. Available now for RFQ at Pacific Component Xchange.
The ISSI IS25WQ040-JNLE(R) is a 4-megabit (512K x 8-bit) low-voltage serial NOR Flash memory device from the IS25WQ family. It features a Multi-I/O SPI interface supporting Standard, Dual, and Quad SPI (QPI) modes, making it well suited for code storage and execute-in-place (XIP) applications in space-constrained, battery-powered designs. The “(R)” suffix denotes reel (tape-and-reel) packaging, corresponding to the IS25WQ040-JNLE-TR ordering option.
Operating from a 1.65V to 1.95V supply with clock frequencies up to 104 MHz, the IS25WQ040 delivers high read throughput in Quad I/O mode while keeping active current low (8 mA typical active read current, 15 uA typical standby), ideal for power-sensitive embedded systems. The device is offered in a standard 8-pin SOIC/SOP package and is rated for the extended/industrial temperature range of -40C to +105C. ISSI is now part of Infineon Technologies.
