be protected independently to prevent accidental
Program or Erase commands from modifying the
memory. Program and Erase commands are writ-
ten to the Command Interface of the memory. An
on-chip Program/Erase Controller simplifies the
process of programming or erasing the memory by
taking care of all of the special operations that are
required to update the memory contents. 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 blocks in the memory are asymmetrically ar-
ranged, see Tables 3A and 3B, Block Addresses.
The first or last 64 Kbytes have been divided into
four additional blocks. The 16 Kbyte Boot Block
can be used for small initialization code to start the
microprocessor, the two 8 Kbyte Parameter
Blocks can be used for parameter storage and the
remaining 32 Kbyte is a small Main Block where
the application may be stored.
Chip Enable, Output Enable and Write Enable sig-
nals control the bus operation of the memory.
They allow simple connection to most micropro-
cessors, often without additional logic.
The memory is offered in a TSOP40 (10 x 20mm)
package and it is supplied with all the bits erased
(set to ’1’).
SUMMARY DESCRIPTION
The M29W002B is a 2 Mbit (256Kb x8) non-vola-
tile memory that can be read, erased and repro-
grammed. These operations can be performed
using a single low voltage (2.7 to 3.6V) supply. On
power-up the memory defaults to its Read mode
where it can be read in the same way as a ROM or
EPROM. The M29W002B is fully backward com-
patible with the M29W002.
The memory is divided into blocks that can be
erased independently so it is possible to preserve
valid data while old data is erased. Each block can
