Marking : 25Q32BVSIG, Part Number: W25Q32BVSSIG
Function: 3V, 32M bit, Serial Flash Memory
Package: SOP 8 Pin Type
The W25Q32BV (32M-bit) Serial Flash Memory provides a storage solution for systems with limited space, pins and power. The 25Q32BVSIG (32M-bit) Serial Flash memory provides a storage solution for systems with limited space, pins and power. The 25Q series offers flexibility and performance well beyond ordinary Serial Flash devices. They are ideal for code shadowing to RAM, executing code directly from Dual/Quad SPI (XIP) and storing voice, text and data. The device operates on a single 2.7V to 3.6V power supply with current consumption as low as 4mA active and 1μA for power-down. All devices are offered in space-saving packages.
Serial Flash Memory is a type of non-volatile memory that stores data using a serial interface instead of a parallel interface. It is also commonly referred to as Serial NOR Flash. Unlike parallel flash memory, which transfers data in parallel over multiple data lines, serial flash transfers data serially, bit by bit, over a single data line.
Additionally, serial flash memory is also commonly used as a bootable medium for microcontrollers, single-board computers, and other embedded systems, as it provides a convenient and reliable storage solution for system firmware and bootloader images.
