GENERAL DESCRIPTION
The W25Q80BV (8M-bit) Serial Flash memory provides
 a storage solution for systems with limited space,
pins  and  power.  The  25Q  series  offers  flexibilit
y  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 ac
tive and 1μA for power-down.
The W25Q80BV array is organized into 4,096 progra
mmable pages of 256-bytes each. Up to 256 bytes
can be programmed at a time. Pages can be erased in
 groups of 16 (4KB sector erase), groups of 128
(32KB  block  erase),  groups  of  256  (64KB  block  erase)
  or  the  entire  chip  (chip  erase).  The  W25Q80BV  
has  256  erasable  sectors  and  16  erasable  blocks  respecti
vely.  The  small  4KB  sectors  allow  for  greater  
flexibility in applications that require
data and parameter storage. (See figure 2.)   
The  W25Q80BV  supports  the  standard  Serial  Peri
pheral  Interface  (SPI),  and  a  high  performance  
Dual/Quad  output  as  well  as  Dual/Quad  I/O  SPI:  Serial  
Clock,  Chip  Select,  Serial  Data  I/O0  (DI),  I/O1  
(DO),  I/O2  (/WP),  and  I/O3  (/HOLD).  SPI  clock  
frequencies  of  up  to  104MHz  are  supported  allowing  
equivalent  clock  rates  of  208MHz  (104MHz  x  2)  for  Dual  I/O  and  416MHz  (104MHz  x  4)  for  Quad  I/O  
when  using  the  Fast  Read  Dual/Quad  I/O  instructi
ons.  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  instru
ction-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,  bottom  or  complement  array  
control, provide further control
flexibility. Additionally, the device
supports JEDEC standard manufacturer
and device identification with a 64-bit Unique Serial Number.
