N25Q256A11ESF40F Datasheet, PDF (7/87 Pages) Micron Technology – Micron Serial NOR Flash Memory

1.8V, 256Mb: Multiple I/O Serial Flash Memory
Device Description
All protocols support XIP operation. For flexibility, multiple XIP entry and exit methods
are available. For applications that must enter XIP mode immediately after powering
up, XIP mode can be set as the default mode through the nonvolatile configuration reg-
ister bits.
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, DIO-SPI, or QIO-SPI)
• Required XIP mode
• Enabling/disabling HOLD (RESET function)
• Enabling/disabling wrap mode
