GENERAL DESCRIPTION

The  W25Q64CV  (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 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.
