Software Features
Embedded Algorithms
Data# Polling and toggle bits
—
Embedded Erase algorithm automatically
preprograms and erases the entire chip or any
combination of designated sectors
—
Provides a software method of detecting program or
erase operation completion
—
Embedded Program algorithm automatically writes
and verifies data at specified addresses
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
Compatibility with JEDEC standards
—
Pinout and software compatible with single-power
supply Flash
Hardware Features
—
Superior inadvertent write protection
Ready/Busy# pin (RY/BY#)
Sector Protection features
—
Provides a hardware method of detecting program or
erase cycle completion
—
—
—
A hardware method of locking a sector to prevent any
program or erase operations within that sector
Hardware reset pin (RESET#)
Sectors can be locked in-system or via programming
equipment
—
Hardware method to reset the device to reading array
data
Temporary Sector Unprotect feature allows code
changes in previously locked sectors
