Description
The M29F400B is a 4 Mbit (512 Kb x8 or 256 Kb x16) non-volatile memory that can be read,
erased and reprogrammed. These operations can be performed using a single 5V 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 M29F400B is fully backward compatible with the M29F400.
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 be protected independently to
prevent accidental Program or Erase commands from modifying the memory. 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 blocks in the memory are asymmetrically arranged, see
Table 19.
and
Table 20.
, 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 K is
a small Main Block where the application may be stored.
Chip Enable, Output Enable and Write Enable signals control the bus operation of the
memory. They allow simple connection to most microprocessors, often without additional
logic.
The memory is offered in TSOP48 (12 x 20 mm) and SO44 packages and it is supplied with
all the bits erased (set to ’1’).
In order to meet environmental requirements, ST offers the M29F400B 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.
ECOPACK is an ST trademark. ECOPACK specifications are available at:
