W25Q128JVSIQ WINBOND

The W25Q128JVSIQ from Winbond Electronics is a high-performance 128-Mbit Serial NOR Flash memory device, belonging to the W25Q128JV series under the SpiFlash trademark. Organized as 16M x 8, it features a standard SPI interface supporting clock frequencies up to 133 MHz for fast data transfer. Operating from a single 2.7V to 3.6V power supply and consuming a maximum of 25 mA during active read, it is designed for low-power, high-reliability applications. With an operating temperature range of -40°C to +85°C, this SMD/SMT component in an SOIC-8 package is ideal for code storage and execution in a wide array of consumer electronics, networking equipment, and industrial systems requiring robust, non-volatile memory solutions.
