Serial flash memory is a type of non-volatile memory that is commonly used for storing data in embedded systems, microcontrollers, and other electronic devices. It is called “serial” because data is read from and written to the memory one bit at a time or in a serial fashion, as opposed to parallel flash memory where data is transferred in parallel over multiple data lines.

The 25Q64BV (64M-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 devices operate 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.
