GENERAL DESCRIPTION
are nonvolatile, electrically block-erasable (flash), pro-
grammable, read-only memories containing 2,097,152
bits organized as 131,072 words (16 bits) or 262,144
bytes (8 bits). Writing or erasing the device is done with
either a 3.3V or 5V V
performed with a 3.3V V

SmartVoltage technology, 12V V
maximum of 100 cycles and may be connected for up
to 100 cumulative hours. These devices are fabricated
with Micron’s advanced CMOS floating-gate process.
into five separately erasable blocks. To ensure that
critical firmware is protected from accidental erasure or
overwrite, the devices feature a hardware-protected
boot block. Writing or erasing the boot block requires
either applying a super-voltage to the RP# pin or driv-
ing WP# HIGH in addition to executing the normal
write or erase sequences. This block may be used to store
code implemented in low-level system recovery. The
remaining blocks vary in density and are written and
erased with no additional security measures.
