accomplished by using high voltage which can be sup-
plied on a separate line.
The embedded WORD WRITE and BLOCK ERASE
functions are fully automated by an on-chip write state
machine (WSM), which simplifies these operations and
relieves the system processor of secondary tasks. The
WSM status can be monitored by an on-chip status
register to determine the progress of program/erase tasks.

GENERAL DESCRIPTION
The MT28F160A3 is a nonvolatile, electrically block-
erasable (flash), programmable, read-only memory con-
taining 16,777,216 bits organized as 1,048,576 words
(16 bits).
The MT28F160A3 is manufactured on 0.22碌m process
technology in a 48-ball FBGA package. The device has an
I/O supply of 2.7V (MIN). Programming in production is

DEVICE MARKING
Due to the size of the package, Micron鈥檚 standard part
number is not printed on the top of each device. Instead,
an abbreviated device mark comprised of a five-digit
alphanumeric code is used. The abbreviated device marks
are cross referenced to Micron part numbers in
Table 1.
