Package Options
48-ball FBGA
48-pin TSOP
44-pin SO
Top or bottom boot block configurations
available
Embedded Algorithms
— Embedded Erase algorithm automatically
preprograms and erases the entire chip or any
combination of designated sectors
— Embedded Program algorithm automatically writes
and verifies data at specified addresses
Software Features
Data# Polling and toggle bits
— Provides a software method of detecting program or
erase operation completion
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
— Superior inadvertent write protection
Hardware Features
Ready/Busy# pin (RY/BY#)
— Provides a hardware method of detecting program or
erase cycle completion
Sector Protection features
— A hardware method of locking a sector to prevent any
program or erase operations within that sector
— Sectors can be locked in-system or via programming
equipment
— Temporary Sector Unprotect feature allows code
changes in previously locked sectors
Hardware reset pin (RESET#)
— Hardware method to reset the device to reading array
data
