Device Description
Device Configurability
The N25Q family offers additional features that are configured through the nonvolatile
configuration register for default and/or nonvolatile settings. Volatile settings can be
configured through the volatile and volatile-enhanced configuration registers. These
configurable features include the following:
• Number of dummy cycles for the fast READ commands
• Output buffer impedance
• SPI protocol types (extended SPI, dual-SPI, or quad-SPI)
• Required XIP mode
• Enabling/disabling HOLD (RESET function)
• Enabling/disabling wrap mode
