IS25LQ040B-JNLA3-TR – Serial NOR Flash – ISSI

The ISSI IS25LQ040B-JNLA3-TR is a 4Mbit (512K x 8) automotive-grade Quad SPI Serial NOR Flash memory in an 8-pin SOIC package, rated -40°C to +125°C. Available now for RFQ from Pacific Component Xchange.

The IS25LQ040B-JNLA3-TR from ISSI (Integrated Silicon Solution Inc.) is a 4Mbit (512 Kbyte) Quad Serial Flash memory device built on a multi-I/O SPI architecture. Organized as 512K x 8 bits, it delivers high-speed, low-pin-count nonvolatile storage for space-constrained embedded designs. The “A3” suffix designates the automotive temperature grade (-40°C to +125°C), while the “JN” package code identifies the industry-standard 8-pin SOIC (150 mil) body. This is supplied on tape-and-reel (-TR).

The device supports Standard SPI, Dual I/O and Quad I/O SPI operation at clock speeds up to 104 MHz, providing up to 52 MB/s continuous data throughput (416 MHz equivalent Quad SPI). It operates from a single 2.3V to 3.6V supply, making it well suited for 3V automotive and industrial systems.
