آیسی NOR Flash W25Q256FVEM - اورجینال -New and original+گارانتی

GENERAL DESCRIPTIONS:
The W25Q256FV(256M-bit)Serial  Flash  memoryprovidesa  storage  solution for  systems  with  limited space,  pins  and  power.  The  25Qseries  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)andstoring voice, text and data. The device operateson 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.
The W25Q256FVarray  is  organized  into 131,072programmable  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 W25Q256FVhas 8,192erasable  sectors  and 512erasable  blocks  respectively.  The  small  4KB  sectors allow for greater flexibility in applications that require data and parameter storage.
The W25Q256FVsupportthe standard Serial Peripheral Interface (SPI), Dual/Quad I/OSPIaswell as 2-clocks instruction cycle Quad Peripheral Interface (QPI): 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/Oinstructions.These  transfer  rates  can  outperform  standard Asynchronous8  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 (executein place) operation.
A Hold pin, Write Protect pin and programmable write protection, with top or bottom array control,providefurther  control  flexibility. Additionally,  the  device  supports  JEDEC  standard  manufacturer  and  device ID and SFDP Register,a 64-bit Unique Serial Numberand three256-bytes Security Registers.
