1.3
Operating Protocols
*Advanced information. Subject to change without notice.
The memory can be operated with three different protocols:
• Extended SPI (standard SPI protocol upgraded with dual and quad operations)
• Dual I/O SPI
• Quad I/O SPI
The standard SPI protocol is extended and enhanced by dual and quad operations. In addition, the dual SPI
and quad SPI protocols improve the data access time and throughput of a single I/O device by transmitting
commands, addresses, and data across two or four data lines.
Each protocol contains unique commands to perform READ operations in DTR mode. This enables high data
throughput while running at lower clock frequencies.
1.4
XIP Mode
Execute-in-place (XIP) mode allows the memory to be read by sending an address to the device and then
receiving the data on one, two, or four pins in parallel, depending on the customer requirements. XIP mode
offers maximum flexibility to the application, saves instruction overhead, and reduces random access time.
XIP mode requires only an address (no instruction) to output data, improving random access time and
eliminating the need to shadow code onto RAM for fast execution.
Nonvolatile configuration register bits can set XIP mode as the default mode for applications that must enter XIP
mode immediately after powering up.
All protocols support XIP operation. For flexibility, multiple XIP entry and exit methods are available.
1.5
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
• Enabling/disabling wrap mode
