IS25LQ040B-JULE-TR – Serial NOR Flash – ISSI

ISSI IS25LQ040B-JULE-TR is a 4Mbit (512K x 8) 3V Quad SPI Serial NOR Flash memory in a leadless USON-8 (2x3mm) package, rated for the extended -40°C to +105°C temperature range and supplied on tape-and-reel. Available now for RFQ from Pacific Component Xchange.

The IS25LQ040B-JULE-TR from ISSI (Integrated Silicon Solution, Inc.) is a 4Mbit (4,194,304-bit) Serial NOR Flash memory organized as 512K x 8 bits. Part of the popular IS25LQ family of low-pin-count Quad SPI flash, it delivers nonvolatile code and data storage in a space-saving leadless USON-8 (2x3mm) package, making it well suited to compact embedded designs where board area, pin count, and power are constrained. The “-TR” suffix indicates the device is supplied on tape-and-reel for automated assembly.

The IS25LQ040B supports standard Serial, Dual, and Quad Multi-I/O SPI operation at clock rates up to 104 MHz (equivalent to 416 MHz in Quad mode), enabling continuous read throughput of up to 52 MB/s. It operates from a single 2.3V to 3.6V supply and supports SPI Modes 0 and 3. The “JU” package code denotes the 8-contact USON 2x3mm package, and this order code corresponds to the extended industrial temperature range of -40°C to +105°C.
