N25Q256A13EF840F Product Details

The N25Q is the first high-performance multiple input/output serial Flash memory device manufactured on 65nm NOR technology. It features execute-in-place (XIP) functionality, advanced write protection mechanisms, and a high-speed SPI-compatible bus interface. The innovative, high-performance, dual and quad input/output instructions enable double or quadruple the transfer bandwidth for READ and PROGRAM operations.


• SPI-compatible serial bus interface 

• Double transfer rate (DTR) mode 

• 2.7–3.6V single supply voltage 

• 108 MHz (MAX) clock frequency supported for all protocols in single transfer rate (STR) mode 

• 54 MHz (MAX) clock frequency supported for all protocols in DTR mode 

• Dual/quad I/O instruction provides increased throughput up to 54  MB/s

• Supported protocols
 – Extended SPI, dual I/O, and quad I/O
 – DTR mode supported on all 

• Execute-in-place (XIP) mode for all three protocols
 – Configurable via volatile or nonvolatile registers
 – Enables memory to work in XIP mode directly after power-on 


• Continuous read of entire memory via a single command
 – Fast read
 – Quad or dual output fast read
 – Quad or dual I/O fast read 

• Flexible to fit application 

 – Configurable number of dummy cycles
 – Output buffer configurable 

• Software reset 

• 3-byte and 4-byte addressability mode supported 

• 64-byte, user-lockable, one-time programmable (OTP) dedicated area 

• An additional reset pin is available on the following devices
  – N25Q256A83ESF40x,N25Q256A83E1240x 

• Erase capability
  – Subsector erase 4KB uniform granularity blocks
  – Sector erase 64KB uniform granularity blocks
  – Full-chip erase 

• Write protection
  – Software write protection applicable to every 64KB sector via volatile lock bit
  – Hardware write protection: protected area size defined by five nonvolatile bits (BP0, BP1, BP2, BP3, and TB)
  – Additional smart protections, available upon request 

• Electronic signature
  – JEDEC-standard 2-byte signature (BA19h)
  – Unique ID of 17 read-only bytes including: additional extended device ID (EDID) to identify device factory options; customized factory data 

• Minimum 100,000 ERASE cycles per sector 

• More than 20 years data retention 

• Packages JEDEC standard, all RoHS compliant
  – V-PDFN-8/8mm x 6mm (also known as SON, DFPN, MLP, MLF)
  – SOP2-16/300mils (also known as SO16W, SO16- Wide, SOIC-16)
  – T-PBGA-24b05/6mm x 8mm (also known as TBGA24)
