IS25WP128-QBLA3-TR – Serial NOR Flash – ISSI

The ISSI IS25WP128-QBLA3-TR is a 128Mbit (16MB) 1.8V Serial NOR Flash memory with a 133MHz multi-I/O SPI / QPI DTR interface, supplied in an 8-pin SOIC (208mil) package on tape and reel. The -QBLA3 suffix denotes the automotive (-40C to +125C) temperature grade.

The IS25WP128-QBLA3-TR from ISSI (Integrated Silicon Solution, Inc.) is a 128Mbit (16Mbyte) 1.8V Serial NOR Flash memory device from the IS25WP128 family. It delivers high-performance non-volatile code and data storage in a low-pin-count package, making it well suited to embedded systems that demand limited board space, low power consumption, and fast random access. The “A3” grade in the part number denotes the automotive (-40C to +125C) temperature range, and the “-TR” suffix indicates tape-and-reel packaging for automated, high-volume SMT assembly.

Built on a 1.65V to 1.95V single supply rail, the IS25WP128 communicates over a 4-wire SPI bus and supports standard SPI, Fast, Dual, Dual I/O, Quad, Quad I/O, and full QPI operating modes, as well as Double Transfer Rate (DTR). With clock frequencies up to 133MHz, the Quad interface yields an equivalent throughput of up to 532MHz (133MHz x 4), providing fast execute-in-place (XIP) code fetch and data streaming.
