Software Features
CFI (Common Flash Interface) compliant
– Provides device-specific information to the system, allowing host
software to easily reconfigure for different Flash devices
Erase Suspend/Erase Resume
– Suspends an erase operation 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 program or erase operation
completion
– Unlock Bypass Program Command
Reduces overall programming time when issuing multiple program
command sequences
Hardware Features

Ready/Busy# pin (RY/BY#)
– Provides a hardware method of detecting program or erase cycle
completion
Hardware reset pin (RESET#)
– Hardware method to reset the device to reading array data
WP#/ACC input pin
– Write protect (WP#) function allows protection of two outermost
boot sectors (boot sector models only), regardless of sector protect
status
– Acceleration (ACC) function provides accelerated program times
