GENERAL DESCRIPTION
The MT28F004B5 (x8) and MT28F400B5 (x16, x8)
are nonvolatile, electrically block-erasable (Flash),
programmable, read-only memories containing
4,194,304 bits organized as 262,144 words (16 bits) or
524,288 bytes (8 bits). Writing or erasing the device is
done with a 5V V
PP
voltage, while all operations are
performed with a 5V V
CC
. Due to process technology
advances, 5V V
PP
is optimal for application and pro-
duction programming. These devices are fabricated
with Micron’s advanced 0.18µm CMOS floating-gate
process.
The MT28F004B5 and MT28F400B5 are organized
into seven 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.
