Description
N25Q256
256-Mbit 3 V, multiple I/O, 4-Kbyte subsector erase, XiP enabled, serial flash memory with 108 MHz SPI bus interface
Features
SPI-compatible serial bus interface 108 MHz (maximum) clock frequency 2.7 V to 3.6 V single supply voltage Supports legacy SPI protocol and new Quad
I/O or Dual I/O SPI protocol Quad/Dual I/O instructions resulting in an
equivalent clock frequency up to 432 MHz: XIP mode for all three protocols
– Configurable via volatile or non-volatile registers (enabling the memory to work in XiP mode directly after power on)
Program/Erase suspend instructions Continuous read of entire memory via single
instruction: – 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 supported in all protocols 64-byte user-lockable, one-time programmable (OTP) area Erase capability – Subsector (4-Kbyte) ...
