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.
Features
• 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
• PROGRAM/ERASE SUSPEND operations
• 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
