— 28 mA typical active read current for
(word mode)
— 30 mA typical program/erase current
— 1 µA typical standby current
s Sector erase 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 via programming equipment
Temporary Sector Unprotect feature allows code
changes in previously locked sectors
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 1,000,000 write/erase cycles guaranteed
s 20-year data retention at 125°C
— Reliable operation for the life of the system
s Package options
— 44-pin SO
— 48-pin TSOP
— Known Good Die (KGD)
(see publication number 21257)
s Compatible with JEDEC standards
— Pinout and software compatible with
single-power-supply flash
— Superior inadvertent write protection
s Data# Polling and Toggle Bit
— Detects program or erase cycle completion
s Ready/Busy# output (RY/BY#)
— Hardware method for detection of program or
erase cycle completion
s Erase Suspend/Erase Resume
— Supports reading data from a sector not
being erased
s Hardware RESET# pin
— Resets internal state machine to the reading
array data
