— Access times as fast as 90 ns
sector
■ Ultra low power consumption (typical values at
■ 20-year data retention at 125°C
5 MHz)
■ Package option
— 0.2 µA Automatic Sleep Mode current
— 0.2 µA standby mode current
— 5 mA read current
— 48-ball FBGA
■ Compatibility with JEDEC standards

single-power supply Flash
— 15 mA program/erase current
■ Flexible sector architecture
— Superior inadvertent write protection
— One 16 Kbyte, two 8 Kbyte, one 32 Kbyte, and
seven 64 Kbyte sectors (byte mode)
■ Data# Polling and toggle bits
— Provides a software method of detecting
program or erase operation completion
— One 8 Kword, two 4 Kword, one 16 Kword, and
seven 32 Kword sectors (word mode)
— Supports full chip erase
■ 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
■ 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
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
