W25X05CLSNIG – Serial NOR Flash – Winbond

The Winbond W25X05CLSNIG is a 512Kbit (64K x 8) Serial NOR Flash memory with an SPI interface supporting Single/Dual Output and Dual I/O, up to 104 MHz clock and 2.3-3.6V supply, in an industrial-grade 8-pin SOIC (150-mil) package. Available for quote.

The Winbond W25X05CLSNIG is a 512K-bit (64K x 8) Serial NOR Flash memory from Winbond’s W25X SpiFlash family, designed for code storage and data storage in space-, pin- and power-constrained embedded systems. It communicates over a standard Serial Peripheral Interface (SPI) bus and additionally supports high-performance Dual Output and Dual I/O read modes, delivering high read throughput while using only a minimal pin count. The “I” suffix denotes the industrial operating temperature grade and the “G” denotes green / RoHS-compliant packaging.

With its small 8-pin SOIC (150-mil) footprint (package code “SN”), uniform 4KB sector architecture, and low operating current, the W25X05CLSNIG is well suited to boot code storage, firmware/parameter storage, and configuration memory applications. As a low-density legacy device, it can be difficult to source in production quantities, making it a candidate for after-market and allocation-constrained procurement.
