Description
www.DataSheet4U.com
The M29DW128G is a 128 Mbit (8 Mb x 16) non-volatile memory that can be read, erased
and reprogrammed. These operations can be performed using a single low voltage (2.7 to
3.6 V) supply. At Power-up the memory defaults to its Read mode.
The M29DW128G features an asymmetrical block architecture, with 8 parameter and 62
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 Table 2. Four of the parameter blocks are at the top
of the memory address space, and four 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 M29DW128G has one extra 256 words block (extended block, 128 words factory locked
and 128 words customer lockable) 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 different levels of hardware and software block protection to avoid
unwanted program or erase (modify):
● Hardware protection:
– The VPP/WP provides a hardware protection of the four outermost parameter
blocks (two at the top and two at the bottom of the address space).
● Software protection
– Standard protection
– Password protection
● Additional protection features are available upon customer request.
The memory is offered in TSOP56 (14 x 20 mm) and TBGA64 (10 x 13 mm, 1 mm pitch)
packages.
In order to meet environmental requirements, Numonyx offers the M29DW128G in
ECOPACK® packages. ECOPACK packages are Lead-free. The category of second Level
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. The memory is supplied with all the bits erased (set to ’1’).
