SUMMARY DESCRIPTION
The M28W320B is a 32 Mbit (2 Mbit x 16) non-vol-
atile Flash memory that can be erased electrically
at the block level and programmed in-system on a
Word-by-Word basis. These operations can be
performed using a single low voltage (2.7 to 3.6V)
supply. V
DDQ
allows to drive the I/O pin down to
1.65V. An optional 12V V
PP
power supply is pro-
vided to speed up customer programming.
The device features an asymmetrical blocked ar-
chitecture. The M28W320B has an array of 71
blocks: 8 Parameter Blocks of 4 KWord and 63
Main Blocks of 32 KWord. M28W320BT has the
Parameter Blocks at the top of the memory ad-
dress space while the M28W320BB locates the
Parameter Blocks starting from the bottom. The
memory maps are shown in Figure 5, Block Ad-
dresses.
Parameter blocks 0 and 1 can be protected from
accidental programming or erasure. Each block
can be erased separately. Erase can be suspend-
ed in order to perform either read or program in
any other block and then resumed. Program can
be suspended to read data in any other block and
then resumed. Each block can be programmed
and erased over 100,000 cycles.
Program and Erase commands are written to the
Command Interface of the memory. An on-chip
Program/Erase Controller takes care of the tim-
ings necessary for program and erase operations.
The end of a program or erase operation can be
detected and any error conditions identified. The
command set required to control the memory is
consistent with JEDEC standards.
The memory is offered in TSOP48 (10 X 20mm),
and TFBGA47 (0.75mm pitch) packages and is
supplied with all the bits erased (set to ’1’).
