W25Q16JVUXIQ 16Mbit SPI/Dual/Quad SPI NOR Flash Memory IC 133MHz USON-8
W25Q16JVUXIQ Product Overview
The W25Q16JVUXIQ is a 16Mbit (2MB) Serial NOR Flash memory from Winbond's SpiFlash® family, housed in an ultra-compact USON-8 (2×3mm) package. It supports standard SPI, Dual-SPI, and Quad-SPI interfaces with a maximum clock frequency of 133MHz, achieving an equivalent transfer rate of 532MHz (66MB/s) in Quad-SPI mode. Operating from 2.7V to 3.6V with a temperature range of -40℃ to +85℃, the device supports Execute-In-Place (XIP) directly from the SPI interface, making it ideal for space-, pin-, and power-constrained embedded systems. The W25Q16JVUXIQ is widely used in consumer electronics, networking, industrial control, automotive electronics, and IoT devices.
