GENERAL DESCRIPTION
The MT28F002B3 (x8) and MT28F200B3 (x16/x8)
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
PP
voltage, while all operations are
performed with a 3.3V V
CC
. Due to process technology
advances, 5V V
PP
is optimal for application and produc-
tion programming. For backward compatibility with
SmartVoltage technology, 12V V
PP
is supported for a
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.
The MT28F002B3 and MT28F200B3 are organized
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.
