s
Flexible sector architecture
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
three 64 Kbyte sectors (byte mode)
— One 8 Kword, two 4 Kword, one 16 Kword, and
three 32 Kword sectors (word mode)
— Supports full chip erase
— 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
s
Unlock Bypass Program Command
— Reduces overall programming time when issuing
multiple program command sequences
s
Top or bottom boot block configurations
available
s
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
s
Minimum 1 million erase cycle guarantee per
sector
s
20-year data retention at 125°C
— Reliable operation for the life of the system
s
Package option
— 48-pin TSOP
— 44-pin SO
— 48-ball FBGA
s
Compatibility with JEDEC standards
— Pinout and software compatible with single-
power supply Flash
— Superior inadvertent write protection
s
Data# Polling and toggle bits
— Provides a software method of detecting program
or erase operation completion
s
Ready/Busy# pin (RY/BY#)
— Provides a hardware method of detecting
program or erase cycle completion
s
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
s
Hardware reset pin (RESET#)
— Hardware method to reset the device to reading
array data
