W25Q32JVSSIQ: 32Mb SPI NOR flash memory, a high-speed data storage solution suitable for embedded systems
Product Overview
W25Q32JVSSIQ is a high-performance serial NOR Flash launched by Winbond Electronics in Taiwan, with a capacity of 32Mb (4MB). It supports multiple communication modes such as SPI (Serial Peripheral Interface), Dual SPI, Quad SPI, etc., with a maximum clock frequency of up to 104MHz. It is particularly suitable for embedded system scenarios such as starting storage, configuring parameters, and data recording. This chip adopts the common SOIC-8 package (SOP-8, wide body), has strong adaptability, and is suitable for use in the main control solutions of microcontrollers (such as STM32, ESP32, NXP Kinetis, etc.).
