Summary description
The M29DW128F is a 128 Mbit (16Mb x8 or 8Mb x16) non-volatile memory that can be read,
erased and reprogrammed. These operations can be performed using a single low voltage (2.7
to 3.6V) supply. V
1.65V. At Power-up the memory defaults to its Read mode.
The M29DW128F features an asymmetrical block architecture, with 16 parameter and 254
main blocks, divided into four Banks, A, B, C and D, providing multiple Bank operations. While
programming or erasing in one bank, read operations are possible in any other bank. The bank
architecture is summarized in
memory address space, and eight are at the bottom.
Program and Erase commands are written 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
Chip Enable, Output Enable and Write Enable signals control the bus operations of the
memory. They allow simple connection to most microprocessors, often without additional logic.
The device supports Asynchronous Random Read and Page Read from all blocks of the
memory array.
The M29DW128F has one extra 256 Byte block (Extended Block) that can be accessed using a
dedicated command. The Extended Block can be protected and so is useful for storing security
information. However the protection is irreversible, once protected the protection cannot be
undone.
Each block can be erased independently, so it is possible to preserve valid data while old data
is erased.
The device features four different levels of hardware and software block protection to avoid
unwanted program or erase (modify). The software block protection features are available in 16
bit memory organization only:

The memory is offered in TSOP56 (14 x 20mm) and TBGA64 (10 x 13mm, 1mm pitch)
packages. The 8-bit Bus mode is only available when the M29DW128F is delivered in TSOP56
package. In order to meet environmental requirements, ST offers the M29DW128F in
ECOPACK
Interconnect is marked on the package and on the inner box label, in compliance with JEDEC
Standard JESD97. The maximum ratings related to soldering conditions are also marked on
the inner box label. ECOPACK is an ST trademark. ECOPACK specifications are available at:
www.st.com. The memory is supplied with all the bits erased (set to ’1’).
