Overview

The W25Q128JVPIQ is a 128M-bit (16M-byte) serial flash memory device from Winbond’s SpiFlash® family, designed for systems with limited space, pins, and power. It operates on a single 2.7V to 3.6V power supply and supports Standard SPI, Dual SPI, and Quad SPI interfaces, enabling high-performance data transfer up to 532MHz equivalent clock speed (66MB/s continuous transfer rate) -10. The device features a clock frequency of 133MHz for single/dual/quad SPI modes, providing flexibility for code shadowing, Execute-in-Place (XIP) operation, and data storage -10. Housed in a compact 8-pad WSON package (6mm × 5mm), the W25Q128JVPIQ offers a flexible architecture with uniform 4KB sectors, 32KB/64KB blocks, and page program capability (1 to 256 bytes per page) -10. It supports industry-standard erase/program suspend and resume functions, allowing code execution from other memory arrays during erase cycles -10. Advanced security features include software and hardware write protection, a 64-bit unique ID for each device, 3×256-byte security registers with OTP locks, and volatile/non-volatile status register bits -10. The device provides a minimum of 100,000 program-erase cycles per sector and more than 20 years of data retention -1-10. With power-down current as low as 1µA (typical) and an operating temperature range of -40°C to +85°C, the W25Q128JVPIQ is well-suited for industrial control systems, automotive systems, consumer electronics, networking devices, IoT applications, and telecommunications equipment -7-10.
