W25Q16FWSNIG – Serial NOR Flash – Winbond

The Winbond W25Q16FWSNIG is a 16M-bit (2M x 8) 1.8V Serial NOR Flash memory with Standard/Dual/Quad SPI and QPI, supplied in an industrial-grade 8-pin SOIC-8 (150-mil) package. This W25Q16FW family device is end-of-life/obsolete and available through independent distribution.

Overview

The Winbond W25Q16FWSNIG is a 16M-bit (16,777,216-bit) Serial NOR Flash memory from Winbond’s W25Q SpiFlash family, organized as 2M x 8 bits. Designed for low-power, space-constrained embedded systems, it operates from a single 1.8V supply and communicates over a Standard, Dual, or Quad Serial Peripheral Interface (SPI) as well as QPI mode, making it well suited for code storage (execute-in-place) and data storage in applications where pins, board space, and power are limited.

This specific orderable variant is supplied in an 8-pin SOIC-8 (150-mil) package, qualified for the industrial temperature range and RoHS/green-compliant. The W25Q16FW (1.8V) family has reached end-of-life status, which makes independent distribution an important source for service, repair, and legacy production builds.
