GENERAL DESCRIPTION 

    The ZB25V of non-volatile flash memory device supports the standard Serial Peripheral  Interface (SPI). Traditional SPI single bit serial input and output (Single I/O or SIO) is supported as well as  optional two bit (Dual I/O or DIO) and four bit (quad I/O or QIO) serial protocols. This multiple width interface is  called SPI Multi-I/O or MIO. 

    The SPI protocols use only 4 to 6 signals: ◆ Chip Select (CS#) ◆ Serial Clock (CLK) ◆ Serial Data - IO0 (DI) - IO1 (DO) - IO2 (WP#) - IO3 (HOLD# / RESET#) 

    The ZB25V support the standard Serial Peripheral Interface (SPI), Dual/Quad I/O SPI as well  as 2-clocks instruction cycle Quad Peripheral Interface (QPI) as well as Double Transfer Rate (DTR): Serial  Clock, Chip Select, Serial Data I/O0 (DI), I/O1 (DO), I/O2 (WP#), and I/O3 (HOLD# / RESET#). SPI clock  fre of up to 133MHz are supported allowing e clock rates of 266MHz (133MHz x 2) for Dual  I/O and 532MHz (133MHz x 4) for Quad I/O when using the Fast Read Dual/Quad I/O and QPI instructions.  These transfer rates can outperform standard Asynchronous 8 and 16-bit Parallel Flash memories. The  Continuous Read Mode allows for efficient memory access with as few as 8-clocks of instruction-overhead to  read a 24-bit address, allowing true XIP (execute in place) operation. 

    A Hold pin, Write Protect pin and programmable write protection, with top or bottom array control, provide  further control flexibility. Additionally, the device supports JEDEC standard manufacturer and device ID and  SFDP Register, a 128-bit Unique Serial Number and three 1024-Byte Security Registers. 

    The ZB25V provides an ideal storage solution for systems with limited space, signal  connections, and power. These memories' flexibility and performance is better than ordinary serial flash  devices. They are ideal for code shadowing to RAM, executing code directly (XIP), and storing  reprogrammable data
