Software Features
Supports Common Flash Memory Interface (CFI)
Erase suspend/Erase resume
Suspends erase operations to read data from, or program data to, a sector that is not being erased, then resumes the erase operation.
Data# polling and toggle bits
Provides a software method of detecting the status of pro-gram or erase operations
Unlock bypass program command Reduces overall programming time when issuing multiple program command sequences Hardware Features
Ready/Busy# output (RY/BY#)
Hardware method for detecting program or erase cycle completion
Hardware reset pin (RESET#)
Hardware method of resetting the internal state machine to the read mode
WP#/ACC input pin
Write protect (WP#) function protects the two outermost boot sectors regardless of sector protect status
Acceleration (ACC) function accelerates program timing
Sector protection
Hardware method to prevent any program or erase operation within a sector
Temporary Sector Unprotect allows changing data in protected sectors in-system
