W25X32VSSIG is an integrated serial non-volatile Flash memory supporting the standard serial peripheral interface. This memory is often used for a wide variety of applications such as automotive, industrial, medical and embedded systems. W25X32VSSIG is a Flash memory with a two-wire serial interface, allowing access to 1MBytes of storage with only power, ground, and the two serial data signals required.

Application Field

W25X32VSSIG has been used in a wide range of applications which require the storage of large quantities of data to be retained in memory after power is switched off. Common application fields of W25X32VSSIG are Automotive ECU, Industrial Equipment, Home Appliances and System on Modules, etc.

Working Principle

W25X32VSSIG uses a four-wire serial peripheral interface that consists of a data line, a clock line, and Power. The clock signal synchronizes transmission between the Flash memory device and the memory controller. Data can be read from or written to the device in a single operation or multiple operations. Read operations are accomplished by the device sending the requested information serially on the data line. Write operations are performed by writing data onto the data line and then clocking the serial data into the device. Once the data is written to the device, the controller must wait until the write is complete before attempting to access the same data. The device automatically generates the appropriate reset signals when necessary.

W25X32VSSIG also features advanced architecture to provide high performance, a wide operating voltage range, low power consumption. The device supports a symmetric read-write operation, with a read speed up to 102Mhz and a write speed up to 54Mhz, powering down to 0.2μA. W25X32VSSIG’s storage capacity enables large quantities of data to be stored. The device is also protected from static and dynamic power by its integration of ESD protection.
